OWL 640 VIS-SWIR Analogue

Cooled VGA Surveillance Analogue InGaAs

The OWL 640 Analogue is a rugged, high sensitivity digital VIS-SWIR camera. Using a 640 x 512 InGaAs sensor from SCD, the OWL enables high sensitivity imaging from 0.4µm to 1.7µm. The 15µm x 15µm pixel pitch enables high resolution VIS-SWIR imaging and with less than 50 electrons readout noise, the camera enables the highest VIS-SWIR detection limit.
The OWL 640 analogue will run at 25Hz in CCIR and 30Hz in EIA, enabling high speed digital video with intelligent Automated Gain Control (AGC) . This new on-board AGC will enable clear video in all light conditions.
The camera also features an on-board intelligent 3 point NUC which will provide the highest quality images.
