Cooled VGA SWIR InGaAs Camera: PSEL VGA 15 μm

The Cooled VGA SWIR InGaAs Camera from Photonic Science utilizes specific InGaAs focal plane arrays with low defective pixel count and low dark current.

The InGaAs camera has efficient cooling and stable offset, thus enabling reproducible acquisition for accurate metrology measurements in the SWIR spectrum.

Gigabit Ethernet Vision- and Camera Link-compliant interface facilitates simple integration into present systems.

OEM versions with unique form factors or cooling options are available for integration into particular systems or instruments.

Key Features

  • 16-bit image processing or 14-bit digitization
  • Readout noise down to generally <30 electrons
  • Over 200 fps with a region of interest (ROI)
  • Outstanding linearity response to varying intensities and or exposures
  • Camera Link interface and Gigabit Ethernet
  • Software option: Labview VIs and SDK kit
