Model KV104 MCT Photodiode Series
Model KV104 series is wide electrical bandwidth infrared detector sensor with cutoff wavelength greater than 11 um. The MCT photovoltaic detector covers the spectral range from 2um to 11.5 um. There are several external transimpedance amplifiers (DC or AC coupled) with matched bias circuits. The maximum detector size is 1 mm x 1 mm. The D*(peak,10kHz) is greater than 3 x 1010 Jones. The side looking LN2 pour filled dewar has a 10 hour hold time. The KV104 can also be packaged with Stirling cycle coolers or Joule Thompson coolers.
Options include AR coated windows for 2 to 12 um or 10.6 um, as well as element sizes down to 0.05 mm. Other cutoff wavelengths ( 8 um and 4.5 um ) are also available.
The KV104 is designed for applications where photoconductive MCT detector capabilities are not enough. These are applications which require bandwidth greater than 1 MHz or greater linear dynamic range with photon flux.
The KV104 is designed to be used in systems and instruments which require a very sensitive, linear, high speed detector:
