G7754-01_ETC_KIRD1024E09 Datasheet, PDF (1/3 Pages) Hamamatsu Corporation – Metal dewar type

Infrared detector modules with preamps
Metal dewar type
High sensitivity modules of easy-to-use
These devices combine a dewar type detector with a compatible preamplifier, and easily operate to detect infrared radiation just by
connecting to a DC power supply. InGaAs and InSb detectors are provided as standard devices (liquid nitrogen cooling). Custom-
designed devices with different active areas, FOV or amplifier gain, etc. are also available to meet your specific needs.
Features
Compact integral detector unit
Optimum connections between the detector element and pre-
amplifier allow amplified signals to be easily obtained.

*1: Use only an analog power supply.
Note: Nitrogen hold time: 12 hours or more (at the time of shipment)
Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the
product within the absolute maximum ratings.
