Applications

 

The KMPV is designed to be used in systems and instruments which require a very sensitive, linear, high speed detector/amplifier:

 

  • Step-scan FTIR
  • Time resolved spectroscopy
  • Range finders
  • Trace gas spectroscopy
  • Chemical aerosols detection
 

Description

 

The KMPV series is an integrated high frequency infrared detector/amplifier sensor with wavelengths of 2m m to 12m m. The MCT photodiode is coupled to an internal DC to 20 MHz (50 MHZ or 100 MHz) bandwidth transimpedance amplifier. The output can be ordered as DC, AC or both AC and DC. The broadband D* is greater than 1 x 1010 Jones. The standard Dewar is side-looking with a 10 hour hold time. The standard IR window is ZnSe anti-reflection coated for 2m m to 13m m.

 

The KMPV is designed for applications in which photoconductive MCT detectors are beyond their capabilities: applications which require bandwidth greater than 1MHz or greater linear dynamic range with photon flux.
