Sensors Unlimited (Princeton, NJ), part of Goodrich Corporation, has announced the new SU1024LDH2, a high speed, digital line scan SWIR-indium gallium arsenide (InGaAs) camera. The second generation 1024-pixel, high speed camera features an increased line rate to over 91,900 lines per second, making it suitable for spectral-domain optical coherence tomography (SD-OCT) imaging applications. In the 1.05 microns wavelength band, the new 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. Small (3 inches W × 3 inches H × 2.4 inches L) and cost-effective, the LDH2 SWIR camera can be easily mounted to spectrometers.
