产品系列说明

可选未镀膜版和镀增透膜版，适用于各种红外应用
低色散使色像差相对变得极低
非常适合用于需要坚固光学窗口片的红外应用
此外还提供DLC 镀膜锗窗口片
由于锗的原材料供应链中断，我们的锗材料产品交付周期可能会延长，价格也可能会发生变化。如需了解更多信息，请向我们的客服团队进行咨询。

TECHSPEC® 锗 (Ge) 窗口片有现货，可选三种增透膜: 3 - 5μm波段的增透膜适用于中红外应用，3 - 12μm波段的增透膜适用于宽带多光谱应用, 8 - 12μm波段的增透膜适用于热成像应用。锗光学材料也比较适合做设计波长在8-12μm内的增透膜（AR）镀膜的膜层材料。锗受温度影响严重，透过率随温度的升高而降低，因此，它们只能在100®C以下应用。在设计对重量有严格要求的系统的时候要考虑锗的密度(5.33 g/cm³)。锗主要应用在热成像系统和前视红外（FLIR）领域里面。锗的努氏硬度是780，大概是氟化镁硬度的两倍，这使它比较适合变化光学的IR领域的应用。
