產品概覽

提供未鍍膜或鍍抗反射鍍膜選項,適用於各種红外應用
低色散帶來最小的色像差
非常適用於需要堅固光學裝置的紅外應用
也供應 DLC 鍍膜鍺窗鏡
由於鍺的材料供應鏈中斷，我們的鍺產品的交貨時間可能會增加，價格也會有所變動。欲了解更多訊息，請聯繫我們的客戶服務團隊。
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(Ge) 窗鏡現貨供應，可選三種抗反射鍍膜: 3 - 5μm波段適用於中紅外應用，3 - 12μm波段適用於寬帶多光譜應用, 8 - 12μm波段適用於熱成像應用。由於鍺窗口片的折射率很高 (對於2 - 14μm的光大約為4.0)，因此建議在這些鍺窗口片上使用抗反射鍍膜，以便在所需範圍內實現充足的穿透。鍺受温度影響嚴重，穿透率隨温度的升高而降低，因此，只能適用於100°C以下溫度的應用。在設計對重量有嚴格要求的系统時要考慮鍺的高密度(5.33 g/cm³)。鍺的努氏硬度是780，大約是氟化鎂硬度的兩倍，非常適用於需要堅固光學特性的紅外應用。

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.
