Used for fire and flame prevention detection.
The principle is flame light detection: based on the flame optical radiation generated by material combustion, mainly infrared radiation, the fire phenomenon is detected through corresponding infrared photosensitive components and electronic systems.
The figure below shows a typical spectral curve. Specific parameters are as follows:
Substrate: Ge, Monocrystalline Silicon, ZnSe, ZnS, etc.
Size: Customized as per customer requirements
Specifications: 1.5–2.8 μm, transmittance <1%; 3–5 μm, average transmittance >92%
