KOLMAR TECHNOLOGIES

Series KV104

MCT Photodiodes

Features

 

  • High D* at high frequencies
  • Sizes 2.0 mm to 0.05 mm
  • Wavelength cutoff: 11.5, 8, 4.5 m m
  • Linear
  • Custom configurations available

 

 

Applications

 

The KV104 is designed to be used in systems and instruments which require a very sensitive, high speed detector:

 

  • Laser radar
  • Range finders
  • Trace gas spectroscopy
  • IR DIAL
  • Chemical aerosols detection
  • Heterodyne detection

 

 

Spectral Response

 

Description

 

Series KV104 MCT photodiodes are designed for wide electrical bandwidth applications. The maximum bandwidth is limited only by detector size, which determines RC time constant. A 100 m m pixel size detector is capable of 100MHz bandwidth operation or greater.

 

The spectral response characteristics are determined by the MCT bandgap selected. Standard ranges are 2-12 m m, 2 - 8 m m and 2 - 4.5 m m.

 

The responsivity at 11m m is greater than 4 Amp/Watt and D* (peak, 10kHz, 60FOV) is greater than 3 x 1010 Jones.

 

The standard package is a side-looking LN2 pour-filled Dewar with an AR coated ZnSe window and 8 hour hold time.
