Edmund Optics 的該零件號剩餘庫存有限，一旦耗盡，由於沒有原材料，將無法供應。請聯絡我們的產品支援工程師，協助您找到滿足您需求的替代解決方案。客戶服務部門可為您提供最新的價格和供應情況"。

TECHSPEC®鍺紅外線非球面透鏡能針對中波與長波紅外區域內的廣泛光譜範圍，提供繞射極限的聚焦效能。這些透鏡特別適用於單色光源 (例如量子串級雷射)，可作為標準平凸透鏡的高效能替代方案。

每個非球面透鏡都提供無鍍膜或 BBAR 鍍膜選項。無鍍膜鍺的光線穿透率不足 50%，因此若指定使用無鍍膜透鏡，應考慮採用自訂抗反射 (AR) 鍍膜。每個 BBAR 鍍膜透鏡都能提供超過 95% 的穿透率，特別適合整合到多種 OEM 應用中。如需自訂設計或鍍膜選項，請聯絡我們的銷售部門。

Germanium Optics Handling and Cleaning Guidelines

Germanium optics require special handling and cleaning procedures. Always wear gloves during handling to prevent contamination, and wash hands afterward. Avoid contact between Germanium dust and the eyes, skin, or clothing. When not in use, store optics sealed and covered at temperatures between 20°C and 25°C. Do not expose them to temperatures exceeding 100°C when in use.

Handling Guidelines

Always wear gloves to prevent damage from skin oils.
If Germanium dust is present, take the following precautions:
- Wear safety glasses to protect eyes.
- Use a dust mask or face mask to avoid inhalation.
- Wear gloves to prevent skin contact.
Maintain storage temperature between 20°C and 25°C with humidity below 30%.
Wrap Germanium optics in a lens cloth or pouch and seal in a container when not in use.
Germanium is brittle and heavy — always place it on soft surfaces and avoid dropping it.
