Sensors Unlimited has released the SU1024LDH2 line-scan SWIR-indium gallium arsenide (InGaAs) camera, which is suitable for spectral domain optical coherence tomography (SD-OCT) imaging applications.
The 1024-pixel high-speed camera features an increased line rate to more than 91,900 lines per second.
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 detail beyond the depth capability of current 0.84 micron systems, according to Sensors Unlimited.
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.
The LDH2 SWIR camera measures 3in (W) x 3in (H) x 2.4in (L) and can be mounted to spectrometers.
Optional adapters are also available for C-mount, F-mount or FD-mount lenses for use with machine-vision applications.
The high-speed camera has a wavelength response range from more than 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 also suitable for SWIR imaging applications such as high-speed absorption or emission spectroscopy 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, as well as machine-vision tasks for sorting and monitoring continuous processes.
Sensors Unlimited will be showing the 92kHz shortwave infrared line-scan LDH2 camera at the Association of Research in Vision and Ophthalmology/International Society for Imaging in the Eye (ARVO/ISIE) Meeting on 1 May 2010 on booth six, at the Greater Fort Lauderdale/Broward County Convention Center, Fort Lauderdale, Florida.
