Product Overview

1280×1024, 10μm HgCdTe (MCT) cooled MWIR infrared module, F4.0 aperture, NETD ≤40mK, 25Hz frame rate, default F4 30~150mm continuous-zoom lens; provides SDI / CameraLink / MIPI interface configurations and RS422 control.

Product Features

High-Resolution Cooled Imaging

  • 1280×1024 / 10μm HgCdTe (MCT) cooled MWIR detector with a 3.7~4.8μm spectral response, NETD ≤40mK@25℃ and MRTD ≤350mK (12cy/mrad, minimum FOV); the 25Hz frame rate delivers fine, detailed imaging
  • Cool-down time ≤6min at room temperature (≤8min at high temperature); the start-up screen displays the cool-down time, current cooler temperature and a progress bar

F4 30~150mm continuous zoom

  • Default F4.0 30~150mm continuous-zoom lens (FOV 24.1°×19.4° ~ 4.9°×3.9°, estimated values); supports step/continuous zoom, step/continuous focus, follow focus and one-touch focus
  • Fixed-focus athermalized or fixed-focus motorized-focus lens configurations are also available; optical axis stability ≤2 pixels, parfocality with best-focus point deviation < 10% of total travel over the full temperature range

Three interface configurations

  • Any one of three interface configurations — SDI (DC 22~30.3V) / CameraLink (DC 18~32V) / MIPI (DC 12~24V) — with RS422 serial control; external sync input/output/adaptive supported
  • Complete image processing capabilities including solar protection, blind pixel replacement, 0~7 levels of image enhancement, 48 false color palettes, crosshair reticle and test pattern output

Rugged Environmental Performance

  • Operating temperature -40~+60℃, storage temperature -45~+65℃, vibration ≥2g (15~500Hz), shock 15g half-sine
  • Complete unit ≤234×118×116mm, weight ≤2.5kg (±50g), 100% domestically sourced
