PRINCETON, N.J., 2 April 2009. Sensors Unlimited Inc. in Princeton, N.J., is introducing the high performance SWIR optimized 50-millimeter lens for shortwave infrared cameras used in advanced military infrared imaging and other shortwave infrared viewer applications in the 0.7 to 1.7 micron spectral range.

The SWIR camera lens is ruggedly designed for military infrared imaging applications, as well as other industrial and commercial infrared camera applications.

High performance imaging applications include 24-hour, day and night surveillance (with human recognition at 250-meter range), unmanned aerial vehicles (UAVs), imaging lasers, and driver vision enhancement.

The 50-millimeter focal length lens has a manual locking focus for steady performance with reliable operation and advanced optics that deliver greater than 90 percent throughput from 0.9 to 1.7 microns. It has a fixed aperture at f/1.4 that provides sharp imagery, with low distortion. SWIR stands for shortwave infrared.

The SWIR SOLO 50 performs with Sensors Unlimited's high sensitivity, InGaAs-SWIR, KT and SD camera families. Designed for large focal plane arrays (up to
640-by-512 with a 25-micron pixel pitch), the camera optics are for demanding, low-light-level imaging tasks.
