Pyroelectric detectors - InSb series

Indium Antimode (InSb) Series Detectors

Liquid Nitrogen cooling IR detectors used to detect over a spectral range of 1.0 to 5.5μm.

There are two types of InSb detectors: the DInSb5-De(x) and DInSb5-HS.

  • DInSb5-De(x) is the liquid nitrogen cooling detector. x-01/02/04/07, there are four kinds of active sizes for this type of detector, which is suitable for general measurement which must work with the preamplifier.
  • DInSb5-HS is the liquid nitrogen cooling and high-speed response detector, integrated preamplifier, and response time less <25 ns.
  • Detector devices are packaged in the DEC-(x) series detectors housing connected to the spectrograph slits.

InSb detectors application advice

  • DInSb5-De(x) and DInSb5-HS detectors are the liquid nitrogen cooling Near-IR, Mid-IR detectors. In order to facilitate connection with Gilden Photonics spectrograph, the liquid nitrogen Dewar built-in the DEC-(x) detectors housing, x corresponds to different types of Dewar.
  • DInSb5-De(x) deries are not intregrated to a preamplifier, so must be connected to one other preamplifier, ZAMP or ZPA-7 are recommended. Or using the DCS300PA Data acquire system and the lock-in amplifier as the data acquisition equipment.
  • DInSb5-HS is the high speed response detector that can be used for the IR time resolved measurement, can be directly connected with Oscilloscopes
  • Providing liquid nitrogen for customers themselves. When the Dewar is almost filled with liquid nitrogen, it can maintain for 8 hours.
