This is a photodetector capable of measuring 3.34 µm, 4.26 µm, 4.47 µm, and 4.71 µm.
Manufacturer: VIGO Photonics (Poland) The "4EF-5" is a multi-band, 4-channel infrared detector module. The Peltier-cooled optoelectronic multi-junction 2x2 array detector features an InAsSb (Indium Antimonide) heterostructure, with an integrated 4-channel TIA and TEC controller. This device includes four bandpass filters [Center wavelengths 3.34 µm (CH1), 4.26 µm (CH2), 4.47 µm (CH3), 4.71 µm (CH4)], making it an ideal module for gas detection. ● Detected gases: CH4 (Methane), C2H6 (Ethane), CO2 (Carbon Dioxide), N2O (Nitrous Oxide), CO (Carbon Monoxide) ● Built-in TEC controller ● Easy to integrate ● Many accessories available ● Other wavelength filter options
