PI/Acton has introduced the 2D-OMA V: 320, a 2-DInGaAs focal plane (FPA) camera with sensitivity up to 1.7 µm. The detector uses a 320 x 256 format array with 30 by 30-µm pixels and is cooled to -100°C using liquid nitrogen. The camera produces greater than >50 full frames per second by the use of 5 megapixel/second readout. Other features include software-controlled high- and low-gain modes for low-light or high-dynamic range operation and online flat field (nonuniformity) and background correction. The detector employs a single sapphire window in the optical path for high throughput. Fluorescence imaging in the infrared region offers several advantages over the traditional techniques including reduced auto-fluorescence (visible background) and higher contrast. Deep cooling reduces the dark current, a significant noise source in IR detectors, and allows long integration times required to detect the low-light features. The camera is also capable of very short exposures (~20usec) for time-resolved imaging applications.
