The OWL SW1.7 CL-640 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 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 an analog output, the OWL 640 will run at 25Hz in CCIR and 30Hz in EIA, 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.
The OWL 640 also features an on-board intelligent 3 point NUC which will provide the highest quality images
