Two-stage, cooled mid-IR detector peaks between 4.3 and 4.5µm

OPTO DIODE BXT2S-28T high-performance, two-stage, cooled, lead selenide (PbSe) detector operates in the mid-infrared (IR) spectral region with peak sensitivity between 4.3 and 4.5µm. The cooler on the device allows the detector element to operate as low as -45 °C to maximize detectivity (D*). Device features improved responsivity of 7.5 x 104 V/W (typical). The reliable device provides high sensitivity when monitoring small changes in gas mixtures. Product is packaged in a TO8 can with a 4 mm² active area, and a flat sapphire window. Absolute ratings for storage and operating temperatures range from -40 °C to +85 °C.
