PRINCETON, N.J., May 4, 2010 — Sensors Unlimited, part of Goodrich ISR Systems, has released the SU1024LDH2, a high-speed, digital line-scan SWIR (short wavelength infrared) indium gallium arsenide camera. The second-generation 1024-pixel camera features an increased line rate of >91,900 lines/s, making it suitable for spectral-domain optical coherence tomography (SD-OCT) imaging applications. In the 1.05-µm wavelength band, the imager can capture detailed 3-D SD-OCT volumes of the retina, choroidal vasculature and nerve head, offering important detail beyond the depth capability of current 0.84-µm systems.
The compact camera housing features both metric and SAE mounting holes on multiple sides for easy integration into existing systems or for other positioning purposes. Measuring 76.2 × 76.2 × 61.0 mm, the cost-effective 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.
Wavelength response range is from 0.8 to 1.7 µm, with a 25-µm pixel pitch and aperture heights of 25 or 500 µm. The camera features integrate-while-read snapshot acquisition, and the operator-selectable trigger modes include free run, single line per trigger, programmable exposure and gated burst.
Applications include 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-to 1700-nm range. Other uses 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.
