HgCdTe room temperature photovoltaic infrared detectorPV-5-0.1x0.1-TO39-NW-90

PV-5-0.1x0.1-TO39-NW-90 in an uncooled photovoltaic IR detector based on HgCdTe heterostructure for optimal performance and stability. Its specific wavelength (λspec) is 5.0 µm and its active area (A) is 0.1 mm × 0.1 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.
