OWL 640 SWIR Digital

Stabilised VGA Surveillance Digital InGaAs

The OWL SW1.7 CL-640 is a rugged, high sensitivity digital 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 highest resolution VIS-SWIR image and with less than 50 electrons readout noise the OWL 640 enables the highest VIS-SWIR detection limit.

Available with a CameraLink output, the OWL 640 will run at up to 120Hz, enabling high speed digital video with intelligent auto AGC. This new feature On-board Automated Gain Control (AGC) will enable clear video in all light conditions.

It is available in both C-mount and M42-mount.
