Photonic Science - Cooled VGA SWIR InGaAs Camera
The Cooled VGA SWIR InGaAs Camera uses selected InGaAs focal plane arrays with low dark current and low defective pixel count. Thanks to efficient cooling and stable offset, the InGaAs camera allows reproducible acquisition for precise metrology measurements in the SWIR spectrum. Camera Link and Gigabit Ethernet Vision compliant interface enables easy integration into existing systems. OEM versions with special form factors / cooling options are available for integration into specific instruments / systems.
14-bit digitization / 16-bit image processing
Read out noise down to typically <30 electrons
>200 fps with region of interest ROI
Excellent linearity response to varying intensities and / or exposures
Gigabit Ethernet & Camera Link interface
