Analysis of Core Principles and Applications of Laser Lens System (Part 3)
Key Technical Features and Challenges
- High Precision Requirement: The processing precision of optical mirrors is usually at the nanoscale; any defect will affect the spot quality and system performance.
- Thermal Management: 尤其在高功率激光应用中,会产生大量热量。需要优秀的散热设计(例如使用低热膨胀系数的材料,如熔融石英)以防止镜头的热变形。
- Laser-Induced Damage Threshold (LIDT): Les revêtements et matériaux sur la lentille doivent être capables de résister à l'irradiation de lasers haute puissance sans être endommagés.

msgid "Special Coatings: It is necessary to design anti-reflection coatings (to reduce reflection loss) and high-reflection coatings for specific laser wavelengths."
msgstr "特殊涂层:有必要为特定激光波长设计抗反射涂层(以减少反射损失)和高反射涂层。"

- Cost: 特别是对于涉及复杂光学组件的镜头,如衍射光学元件(DOE)和非球面镜,设计和制造成本非常高。
