Dual-wavelength, large format sensor features an unprecedented high sensitivity that captures images from both the visible and short wave infra red wavelengths
Sensors Unlimited (SUI) announces its 640x512 pixel, dual-wavelength SU640SDVVis-1.7RT visible-InGaAs area camera, which it describes as a breakthrough.
The new dual-wavelength, large format sensor features an unprecedented high sensitivity that captures images from both the visible and the short wave infra red (SWIR) wavelengths, from 400nm to 1700nm.
The focal plane array (FPA) simultaneously images in both wavelengths, providing a readily recognisable, combined image with unparalleled high resolution.
Compact and versatile, the new Visible-InGaAs FPA dramatically increases responsivity with quantum efficiency of 45% at 800nm, an "unprecedented" 80% at 1310nm, and 75% at 1550nm on a small 25 micron pitch.
The visible-InGaAs area camera operates with increased sensitivity across the visible and SWIR spectral range with a 100% pixel fill factor.
The SWIR video camera has both EIA-170 analogue and simultaneous 14-bit digital video CameraLink compatible outputs.
Operating at room temperature, the solid-state, compact camera features factory set non-uniformity corrections at eight operational settings.
Other features include individual pixel correction, external triggering and windowing.
Applications for the high resolution, visible-SWIR detector include hyperspectral imaging and imaging both eye-safe and visible lasers simultaneously, which is particularly useful for seeing laser designators.
Industrial uses span commercial markets such as astronomy, wafer inspection, wavefront sensing, thermography and spectroscopy.
The Visible-InGaAs dual-wavelength focal plane array is available in several popular geometries, including the 320x240 pixel resolution on a 40 micron pitch.
The 320x256 and 640x512 pixel element arrays are both available on a 25 micron pixel pitch.
