Germanium (Ge) lens
Transmission rate of around 46% without anti-reflective coating in the wavelength range of 1.8 to 23 μm.
- Approximately 46% transmittance without a coat. - Over 90% transmittance due to anti-reflective (AR) coating. - Usable outdoors with DLC coating. - Flat spectral transmittance characteristics with no deep absorption bands in the 8-14μm range. - High refractive index allows for the creation of lenses with short focal lengths and gentle curvature. - Transmittance decreases with heating, so cooling is recommended when used in high-temperature environments.
