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.
