Sensors Unlimited, Goodrich ISR Systems has released the SU1024LDH2, a high-speed, digital line scan SWIR-indium gallium arsenide (InGaAs) camera. The second generation 1,024-pixel camera features a line rate of more than 91,900 lines per second, making it ideal for spectral-domain optical coherence tomography (SD-OCT) imaging applications. In the 1.05 microns wavelength band, the imager can capture detailed 3D SD-OCT volumes of the retina, choroidal vasculature and nerve head, offering important detail beyond the depth capability of current 0.84 micron systems.
The compact camera housing features both metric and SAE mounting holes on multiple sides for easy configuration into existing systems or for other positioning purposes. Small (3 x 3 x 2.4 inches) and cost-effective, the LDH2 SWIR camera can be easily mounted to spectrometers. Optional adapters are also available for C-mount, F-mount or FD mount lenses for use with machine vision applications.
Goodrich's high-speed camera has a wavelength response range from over 0.8 microns to 1.7 microns with a 25 micron pixel pitch and aperture heights of 25 microns or 500 microns. The SU1024LDH2 provides an integrate-while-read snapshot acquisition and the operator-selectable trigger modes include free run, single line per trigger, programmable exposure, or gated burst.
The LDH2 is ideal for SWIR imaging applications, such as high-speed absorption or emission spectroscopy for use in combustion research or for agricultural/food product inspection. These applications are based on detecting the moisture, lipids, proteins, or other molecular vibration absorbance bands in the 800-1,700nm range. Other applications include high-speed inspection of silicon boules or wafers for photovoltaics, solar cell/panel inspection, integrated circuits, and many machine vision tasks for sorting and monitoring continuous processes.
