IR photovoltaic detector PVI series

HgCdTefor gas analysisuncooled

PVI-4-1x1-TO39-NW-36 is an uncooled photovoltaic IR detector based on HgCdTe heterostructure for optimal performance and stability, optically immersed to enhance the parameters. Its specific wavelength (λspec) is 4.0 µm and its optical area (Ao) is 1 mm × 1 mm. The cut‑on wavelength (λcut-on) can be optimized upon request. Applying a reverse bias (Vb) may significantly increase response speed and dynamic range. While this improves performance at high frequencies, be aware that the 1/f noise appearing in biased detectors may reduce performance at low frequencies. The detector is available in the TO39 package without a window. Features Spectral range: 2.3 to 4.4 µm Back-side illuminated Room temperature operation Unique immersion lens technology applied No bias required No 1/f noise No minimum order quantity required Applications Gas detection, monitoring and analysis: CH4, C2H2, CH2O, HCl, NH3, SO2, C2H6, CO2 Breath analysis: C2H6, CH2O, NH3 Explosion prevention Exhaust gas denitrification Emission control (exhaust fumes, greenhouse gases) Contactless temperature measurements (metal industry)
