Description

The KMPV series is an integrated high frequency infrared detector/amplifier sensor covering wavelengths of 2um to 12um. The HgCdTe photodiode is coupled to an internal DC to 10 MHz (20 MHZ, 30 MHz, or 50 MHz) bandwidth transimpedance amplifier. The output can be ordered as DC, AC or both AC and DC. The broadband D* is greater than 2 x 10¹⁰ Jones. The standard Dewar is side-looking with a 12 hour hold time. The standard IR window is ZnSe anti-reflection coated for 2um to 13um wavelength band. The KMPV are designed for applications for which photoconductive MCT detectors are beyond their capabilities: applications which require bandwidth greater than 1MHz, greater linear dynamic range with photon flux and responsivity independent of detector bias .
