Used for human body detection.
Reflective and scattering losses are required to be as low as possible, with the average transmittance generally required to be above 98%.
The figure below shows a typical spectral curve. Specific parameters are as follows:
Substrate: Ge, monocrystalline silicon, etc.
Size: Customized as per customer requirements
Specifications: 8–12 μm, average transmittance >98%
