Uma utshala imali ohlelweni lwe-CO2 laser, kungakhathaliseki ukuthi ukusika i-acrylic, ukubaza ukhuni, noma ukumaka insimbi, ikhwalithi yama-optics akho inquma ngqo ukunemba nokusebenza kahle komsebenzi ngamunye. Abasebenzisi abaningi bagxila kuphela emandleni ethiyubhu noma kuzilungiselelo zesoftware, kodwa-ke ilensi ye-laser iyisici esihlakaza futhi sigxile ububanzi ebuhlotsheni bakho bokusebenza. Ilensi esezingeni eliphezulu inciphisa ukulahleka kwamandla, ikhiqiza imiphetho ehlanzekile, futhi inciphisa isikhathi sokulungisa, kanti ilensi embi ingasakaza ukukhanya, ishise kakhulu, futhi ikhiqize imiphumela engaguquki. Ezinkampanini ezithembele ezinhlelweni ze-laser ukuze zikhiqize, ukuqonda ukuthi ungakhetha kanjani ilensi ye-laser engcono akuyona nje imininingwane yobuchwepheshe — kuyisinqumo samasu esithinta ukukhiqiza, izindleko ngezingxenye, kanye nekhwalithi yomkhiqizo wokugcina. Lo mhlahlandlela uzokuhambisa ngemininingwane ebalulekile, izinkambiso zokukhetha, izincomo zamabhrendi, nemikhuba yokugcina ukuze ukwazi ukwenza ukuthenga okunolwazi oluzosebenzela umsebenzi wakho iminyaka ezayo. Kungakhathaliseki ukuthi ubuyekeza umshini okhona noma wakha uhlelo olusha kusukela ekuqaleni, ulwazi olungezansi luzokusiza ugweme izinkinga ezijwayelekile futhi uzuze ukusebenza okuhle kakhulu kobubanzi.

I-CO2 laser lens iyisici esiqondile sezinto zokubuka ezakhiwe cishe ngokuphelele kusuka ku-zinc selenide (ZnSe) ngenxa yokudlulisela kwayo okuhle kakhulu ku-wavelength eyi-10.6-micrometer lapho ama-CO2 laser akhipha khona. Le nto ivumela ngaphezu kuka-99% wamandla e-infrared ukuthi adlule ngenkathi ibekezelela ukushaqeka okushisayo kusuka kumafutha anamandla aphezulu. Ilensi ngokwayo igaywa ibe yisimo esithile esiyindilinga — ngokuvamile isimo se-meniscus — esigxilisa ifutha elihambisanayo elivela ku-laser tube endaweni encane kakhulu ebusweni bezinto. Ububanzi baleyo ndawo egxilisiwe, enqunywa ubude bokugxila kwelensi, bunquma ububanzi be-kerf ezinhlelweni zokusika kanye nesinqumo emisebenzini yokubaza. Ngokwesibonelo, ilensi enobude bokugxila obuyi-2.0-inch ikhiqiza indawo encane kakhulu efanele ukubaza kahle, ngenkathi ilensi eyi-4.0-inch ihlinzeka ngobude obukhulu bokugxila obufaneleka kakhulu ekusikeni izinto ezijiyile. Ilensi ngayinye iphinde ibe nokugqoka okungabonakali ezindaweni zombili, ngokuvamile ukugqoka okuningi kwe-dielectric okuthuthukisa kakhulu ukudlulisela futhi kuvikela ilensi ye-zinc selenide ekugugulekeni nasekulimaleni ngokomzimba. Ukuqonda lezi zinto eziyisisekelo — into, ubude bokugxila, nokugqoka — kuyisinyathelo sokuqala sokufanisa ilensi nomshini wakho othize nezidingo zakho.

Ngaphandle kwempahla eluhlaza, imininingwane eyinhloko yelensi ye-CO2 laser ihlanganisa ubude bokugxila, ububanzi obucacile, nobunzima bomphetho. Ubude bokugxila buqondisa kakhulu ibanga lokusebenza phakathi kwelensi nempahla, ngakho-ke ilensi enobude bokugxila obufushane kufanele igcinwe iseduze kakhulu nomsebenzi ngenkathi ubude bokugxila obude buvumela ibanga elikhulu lokuma. Ububanzi obucacile ububanzi obusebenzisekayo belensi; ububanzi obukhulu bubamba okwengeziwe komgqomo futhi bungakwazi ukubhekana namazinga amandla aphezulu, kodwa futhi budinga indawo enkulu yokugxila. Ubunzima bomphetho bubalulekile ukuze kube nokuqinisa ukufakwa, ikakhulukazi ezindaweni ezinokudlidliza okuphezulu njengezinsika zesitayela samalaser cutters. Amanye amalensi amaningi anamuhla futhi ahlanganisa umklamo we-aspheric noma we-meniscus ukunciphisa ukuhlukana kwe-spherical, okwenza ichashaza lokugxila libe libukhali kakhulu futhi kuthuthukise ukuminyana kwamandla emgqeni wokunquma. Yonke le mininingwane yobunjiniyela iholela kulokho okubizwa ngokuthi i-laser light lens assembly, lapho ilensi ifakwe khona ebhodweni noma ebambeni elivikela isakhi futhi livumela ukuhlanza nokulungisa kalula. Lapho uhlola ukuthenga okungaba khona, hlola njalo ukuthi ilensi yakhelwe i-wavelength, izinga lamandla, kanye nefomethi yokufakwa kwe-laser yakho - ngaphandle kwalokho ngisho ne-optic ebiza kakhulu izosebenza kabi.

Isiciqalo futhi esibaluleke kakhulu lapho ukhetha ilensi entsha ukuhambisana nomfutho wamandla we-laser tube yakho. Ilensi elinganiselwe ku-80 watts ingase yonakale ngaphakathi noma i-coating ingahluleka uma isetshenziswa ne-tube engu-150 watts, kanti ilensi elinganiselwe ku-200 watts iphephile ngokuphelele kumshini onamandla aphansi kodwa ingase ibize kakhulu kunokudingeka. Ngokwesibonelo, izitolo eziningi ezisebenzisa i-CO2 laser engu-150 watts zidinga ilensi enesisekelo esijiyile se-ZnSe kanye ne-coating eqinile engamelana nomthwalo wokushisa wemijikelezo yokusika ende. Ubude bokugxila (focal length) kufanele futhi buhambisane nebanga lokusebenza le-Z-axis yomshini wakho: uma ilensi igxila kude kakhulu noma kuseduze kakhulu, uhlelo alukwazi ukuthola indawo efanele ye-beam ebusweni bezinto. Ngaphezu kwamandla, uhlelo oluhlosiwe lunomthelela omkhulu ekukhetheni. Ukusika kudinga ilensi egcina i-kerf engaguquki ezintweni ezijiyile, ngakho-ke ubude bokugxila obude (njengama-intshi angu-4.0 noma 5.0) kuvame ukuncanyelwa ngoba bunikeza ukujula okukhulu kokugxila futhi kunciphisa ingozi yokuthi umbhobho ukhahlele into ngesikhathi sokusika umugqa. Ukubaza, ngakolunye uhlangothi, kuzuza ubude bokugxila obufushane (ama-intshi angu-1.5 kuya ku-2.5) akhiqiza indawo encane nesinqumo esiphezulu sezithombe ezinemininingwane nombhalo.

Esinye isici esibalulekile ukucabangela ukulinganisela phakathi kwekhwalithi nezindleko okufanele ibhizinisi ngalinye likwazi ukukubhekana nakho. Amalensi ashibhile avela kubakhiqizi abangaziwa ayathandeka ngoba angabiza ingxenye encane yezinto ezisezingeni eliphezulu, kodwa avame ukusebenzisa i-zinc selenide esezingeni eliphansi, izendlalelo ezincane, namalungiselelo avulelekileyo aphumela ekuhlakazekeni okukhulu kwe-beam nokubola okusheshayo. Ilensi yelaser light yebhajethi ingasebenza emahoreni ambalwa okuqala, kodwa izokwenza amandla amaningi esikhundleni sokuwudlulisa, okuholela ekubeni kube nomlilo lapho ilensi ngokwayo iba umthombo wokushisa okubola isendlalelo nakakhulu. Ngokuhamba kwesikhathi, lokhu kwandisa izindleko zokugcinwa, kunciphisa isivinini sokusika, futhi kukhiqize imiphetho eluhlaza edinga ukuqedwa okwesibili. Ngokuphambene, ilensi ye-ZnSe eyenziwe kahle evela kumphakeli omethembayo igcina ukusebenza okuzinzile emahoreni ayizinkulungwane, ihlinzeka ngezindleko zokuba nazo ezansi ngisho noma intengo yokuqala iphakeme. Lapho uhlola izindleko, khumbula ukuthi ilensi iyisilinganiso esincane senani eliphelele lesistimu; ukutshala imali eyengeziwe engu-$50 noma $100 entweni esezingeni eliphezulu kungonga izikhathi eziningi kulokho ngokunciphisa isikhathi sokungasebenzi, izingxenye ezimbalwa ezinganqatshelwe, kanye nesikhathi eside sokuphila. Njalo cela igrafu yokudlulisela eqinisekisiwe bese uhlola ukuthi isendlalelo senzelwe i-wavelength namandla akho athile.

Phakathi kwamagama ahlonishwa kakhulu ku-CO2 laser optics yi-II-VI Infrared, umkhiqizi waseMelika ohlinzeka ngamalensi amaningi e-OEM asetshenziswa abakhi bemishini enkulu ye-laser. Amalensi e-II-VI enziwa nge-high-purity chemical vapor deposition (CVD) ZnSe futhi ahlanganiswe nezendlalelo zokuvimbela ukubonisa ezinelungelo lobunikazi ezihlinzeka ngemingcele yomonakalo ehlukile namazinga okudlulisa angaphezu kuka-99.5%. Abakhiqizi abaningi bemishini, okubandakanya i-Trotec, i-Epilog, ne-Universal, bathumela izinhlelo zabo nge-optics ye-II-VI njengemishini ejwayelekile, okuyinkomba eqinile yokwethembeka kohlobo. Ngoba amalensi e-II-VI asetshenziswa njengesilinganiso embonini, atholakala kabanzi kubathengisi abagunyaziwe nabathengisi be-aftermarket. Uma umshini wakho wawuqale uza nelensi ye-II-VI, ukuyishintsha ngomkhiqizo wangempela we-II-VI kuqinisekisa ukuthi ugcina ikhwalithi efanayo ye-beam nesivinini sokucubungula. Kubasebenzisi abafuna ukusebenza kwezinga le-OEM ngaphandle kokubiza okwengeziwe kwemishini yoqobo, umugqa we-aftermarket we-II-VI uhlinzeka ngezendlalelo nezinto ezifanayo ngamanani ancintisanayo. Uma uthenga ilensi yangempela ye-II-VI, uthola nemibhalo yokudluliswa okulinganisiwe nobude obugxilile, okuvumela ukuthi uqinisekise ingxenye ngokumelene nokucaciswa kwesistimu yakho.

Enye inketho enhle kakhulu yi-Cloudray’s CVD ZnSe Meniscus Focus Lens, esizuze idumela eliqinile emphakathini we-laser we-aftermarket ngokuletha ikhwalithi eseduze ne-OEM ngentengo efinyelelekayo. I-Cloudray yenza amalensi ayo kusetshenziswa inqubo efanayo ye-chemical vapor deposition njenge-II-VI, futhi umklamo wayo we-meniscus unciphisa kahle i-spherical aberration ukuze kukhiqizwe indawo yokugxila eqinile. Lolu hlobo ludume kakhulu phakathi kwamabhizinisi amancane naphakathi asebenzisa imishini eminingi futhi adinga ukushintsha amalensi njalo ngaphandle kokudlula isabelomali. I-Cloudray inikeza uhla olubanzi lwezindebe zokugxila nosayizi bokufaka ukuze balingane neziningi izinjini ze-CO2 ezenziwe eShayina kanye nemishini eminingi yaseYurophu neyaseMelika. Amalensi abo futhi anesici sokugqoka okuhlala njalo okungavimbeli ukubonakaliswa okubhekana namandla angama-100–150 watts wamandla aqhubekayo ngokwehla okuncane lapho kunakekelwa kahle. Kumakhasimende weHonray Optic, umngane omethembayo umkhiqizi wama-lens opticalnomphakeli, ama-lens e-Cloudray ayisilinganiso esiphakathi esinconywayo esilinganisa ukusebenza, ukwethembeka, kanye nezindleko. Ithimba le-Honray Optic lingakusiza ukuthi ufanise i-lens ye-Cloudray efanele namandla ethiyubhu yakho nesicelo sakho, uqinisekise ukuthi uthola imiphumela engcono kakhulu ohlelweni lwakho lwe-laser.

Ngakolunye uhlangothi, kubalulekile ukuqonda ukuthi kungani izibuko ezishibhile kakhulu ezivela ezimakethe eziku-inthanethi kufanele zigwenywe. Isibuko esibiza amadola ayishumi singenziwa nge-ZnSe esigaywe kabusha noma esingahlanzekile, esithatha amandla amaningi kakhulu e-infrared futhi singaqhekeka noma sihlukanise ngaphansi kwezimo ezijwayelekile zokusebenza. Ubuso obungaphezulu besibuko esinjalo ngokuvamile bungasendlalelo esisodwa noma i-dielectric eboshwe kabi esonakala ngokushesha, okwenza isibuko sibe mnyama futhi singasebenzi ngempela phakathi nezinsuku ezimbalwa zokusebenzisa kakhulu. Okubi nakakhulu, isibuko esishibhile esiyingozi singangcolisa enye indlela yokukhanya ngokukhipha imfucumfucu embobeni yokukhanya, emakhazeni, nasefeni kawoyela wokuvikela wombhobho we-laser uqobo. Ukufaka umbhobho noma ikhaza elonakele kungabiza amakhulu amadola, okwenza isibuko esishibhile sibe ukukhetha okubizayo esikhathini eside. Ezinkampanini ezincikene ekukhiqizeni okungaguquki, ukonga okuncane esibukweni esishibhile akukwazi ukulungisisa ubungozi. Indlela ephephe kakhulu ukuthenga kumikhiqizo esungulwe njenge-II-VI noma i-Cloudray ngokusebenzisa abathengisi abathembekile, noma ngqo kumphakeli owaziyo njenge-Honray Optic, ongakwazi ukuqinisekisa ubuqiniso nemininingwane yesibuko ngasinye abasithengisayo.

Ukuthenga kumphakeli ohlonishwayo kuyindlela ephumelela kakhulu yokuqinisekisa ukuthi uthola ilensi ye-laser eyiqiniso, enokusebenza okuphezulu. Abasabalalisi abagunyaziwe bagcina izinto ezibandayo zamalensi e-ZnSe ukuze kuvinjelwe ukulimala komswakama, banikeze idatha yokuhlola eqinisekisiwe, futhi banikeze nezinqubomgomo zokubuyisa uma ilensi ingafani nezidingo zokufakwa komshini wakho. Izinkampani ezifana ne-Honray Optic, ezikhethekile ku-izingxenye ze-optical nezixazululo ezenziwe ngendlela , amalensi esitoko avela ku-II-VI kanye ne-Cloudray futhi angakwazi ukunikeza iseluleko mayelana nenombolo yengxenye efanele ngokusekelwe kumodeli yakho ye-laser, amandla ethubhu, kanye nesicelo. Uma uthola ilensi, hlola ukupakisha ukuze uthole izitika ze-holographic, izinombolo zamalungu, kanye nemibhalo yesitifiketi abakhiqizi bangempela abayifaka. Amakhowa amaningi abukeka efana ezithombeni kodwa awanawo ama-bevels emiphetho anembayo, umbala wokubuyisa ukukhanya ongaphansi, kanye nekhwalithi yendawo yemikhiqizo eyiqiniso. Uma unokufinyelela ku-Fourier transform infrared spectrometer noma i-simple transmission test rig, ungakala ukudluliswa kwangempela ku-10.6 micrometers bese uyikuqhathanisa nedatha eshicilelwe umkhiqizi; ilensi eyiqiniso ye-II-VI kufanele idlulise ngaphezu kwe-99% ngokumunca okuphansi kakhulu.

Ukuqaphela imikhiqizo yangempela ye-II-VI ikakhulukazi kufanele unake imininingwane embalwa eyisibonakaliso. Amalensi e-II-VI avame ukugxivizwa inombolo yengxenye egxivizwe nge-laser kanye nekhodi yokulandelela i-lot emaphethelweni; lokhu kugxivizwa kuhlala njalo futhi akulula ukukukopisha. Ukugqoka amalensi angempela kunokubukeka okukhethekile okuluhlaza okwesibhakabhaka okumnyama noma okunsomi ngama-engeli athile, kanti izimvunulo ezishibhile zivame ukubonisa umbala oluhlaza okotshani noma obomvu. Ngaphezu kwalokho, amalensi angempela e-II-VI afakwa emaphaketheni avaliwe, angenisa umoya nge-nitrogen, anezikhwama zokomisa ezigcina i-ZnSe yomile ngesikhathi sokuthunyelwa nokugcinwa. Uma ukupakisha kubonakala kulimele, kungavuliwe, noma kungafaki isikhwama sokomisa, ilensi ingase ibe yachayeke emswakeni ongadala ukuthi ukugqoka konakale ngaphambi kokuba uyifake. Ukuze uthole ukuthula okwengeziwe kwengqondo, ungabheka inombolo yengxenye kuwebhusayithi ye-II-VI noma uxhumane nokwesekwa kwamakhasimende abo ukuze uqinisekise ukuthi umthengisi ungumthengisi ogunyaziwe. Uma ungabaza, ukusebenza nomlingani ozinikele njengoHonray Optic — osebenza ngendawo engu-3,000 square meterifekthri kanye neworkshopigxile kuma-optics anembayo — ikunikeza ukufinyelela kumakhono ezobuchwepheshe neziteshi zokuthola izinto eziqeda ukuqagela.

Uma usutshale imali elengqophamlando lensi ye-laser, ukuyihlanza nokuyiphatha kahle kubalulekile ukugcina ukusebenza kwayo nokwandisa impilo yayo. I-ZnSe substrate iyathinteka kakhulu kunengilazi futhi ingakrweshwa kalula yizinto ezirhabaxa, ngakho-ke hlala uphupha uthuli oluxegayo ngomoya ocindezelweyo ngaphambi kokuthinta indawo. Ukuhlanza okujwayelekile, sebenzisa indwangu yelensi noma indwangu ye-microfiber eyenzelwe ngokukhethekile izibuko ze-infrared, bese uyinake ngama-acetone e-spectroscopic-grade noma i-isopropyl alcohol. Sula ngomunye umunwe owodwa kancane ukusuka maphakathi kuya emaphethelweni, ungaze wenze umbuthano, bese uvumela isixazululi ukuba sishaye ngokuphelele ngaphambi kokufaka kabusha ilensi. Gwema ukusebenzisa izihlanzi zasendlini, amanzi ompompi, noma amathawula ephepha, njengoba lezi zishiya izinsalela nemikrweshana emincane eyonakalisa ukudluliswa ngokuhamba kwesikhathi. Ukuze uthole izinsalela eziqinile njengezinto zokubhema ezivela ekusileni i-acrylic noma i-plywood, kungasetshenziswa amaconsi ambalwa okokuhlanza okwe-optical-grade kulandelwe ukugeza kahle ngotshwala. Abasebenzi abaningi bamukela umgomo wokuhlanza ilensi ekuqaleni kweshifti ngayinye bese beyibheka futhi ngemuva kwanoma yiluphi ushintsho lwezinto, ikakhulukazi lapho ushintsha phakathi kwezinto ezibhema kancane njengephepha nezinto ezibhema kakhulu njenge-polycarbonate.

Ukazi ukuthi nini okufanele ubuyekeze ilensi kubaluleke njengokwazi ukuthi uyihlanza kanjani. Ukuhlola ngamehlo ngaphansi kokukhanya okukhanyayo kuzodalula ukulimala kwe-coating, ukubola, noma ukuba mnyama okunciphisa ikhwalithi yomgqomo. Ukuhlolwa okumelwe kokusebenza - sebenzisa ukusika entweni engaguquki bese ukala ububanzi be-kerf noma i-engela esiphethweni - kungabonisa ukuthi ilensi isasebenza kahle yini. Uma ubona ukwehla kwejubane lokusika, ukwanda kobunzima besiphetho, noma isidingo sokukhuphula izilungiselelo zamandla ukuze uthole imiphumela efanayo, ilensi ingase ifinyelele ekupheleni kwempilo yayo ewusizo. Izilensi eziningi ze-ZnSe ezisezingeni eliphezulu ohlelweni olugcinwe kahle zihlala phakathi kwezinyanga eziyisithupha neminyaka emibili kuye ngamahora okusetshenziswa kanye nokuhlanzeka kwendawo. Ukubuyekeza ilensi ngaphambi kokuba yeqe ngokuphelele kuvikela okunye uchungechunge lwe-optical futhi kuvimbele ukuphazamiseka okubizayo ekukhiqizeni. Honray Optic’sizindaba nezibuyekezo zemboniikhasi njalo wabelana ngezindlela ezingcono kakhulu zokunakekelwa kwama-lens nokukhishwa kwemikhiqizo emisha, kusiza amakhasimende ukuthi ahlale enolwazi mayelana namasu amanje okunakekelwa nokuthuthukiswa okutholakalayo.

Ukukhetha ilensi ye-laser engcono kakhulu ye-CO2 laser yakho kuyisinqumo esithinta ngqo ikhwalithi yakho yokukhiqiza, izindleko zokusebenza, nokwethembeka komshini. Ngokuqonda indima yezinto ze-zinc selenide, ubude bokugxila, kanye nezingubo zokuvimbela ukubonakaliswa, ungakwazi ukufanisa ilensi namandla akho omshini akhethekile kanye nesicelo sakho — kungakhathaliseki ukuthi ukusika okusheshayo, ukugawula okuhle, noma inhlanganisela yazo zombili. Ukubeka phambili izibuko zekhwalithi ezivela kumikhiqizo eqinisekisiwe njenge-II-VI noma i-Cloudray, nokuzithola ngabathengisi abathembekile njenge-Honray Optic, kuqinisekisa ukuthi uthola ukusebenza okufakazelwe kanye nempilo ende yesevisi. Gwema isilingo samalensi angabizi kakhulu angalimaza uhlelo lwakho futhi andise izindleko zakho zokuba nomnikazi. Okubaluleke ngokulinganayo, sebenzisa uhlelo oluqeqeshiwe lokuhlanza futhi wazi izimpawu ezikhombisa ukuthi sekuyisikhathi sokushintsha. Ezinkampanini ezithembele ezinhlelweni ze-laser njengengxenye eyinhloko yemisebenzi yazo, ukutshala imali elensini ye-laser light efanele nokuyinakekela kahle kungenye yezithuthukisi ezingabizi kakhulu ongazenza. Ukuze uthole izincomo eziqondene nawe kanye nokukhethwa okuphelele kwamalensi e-laser afakazelwe, thinta ochwepheshe e-Honray Optic — uchwepheshe.umkhiqizi we-optical lens enolwazi kanye nohlu lwemikhiqizo ukuze kusekelwe impumelelo yakho.
