Fixed Focal Length Lenses for SWIR Cameras

Navitar introduces four new fixed focal length imaging optics specifically designed for SWIR (short wave infrared) cameras and applications and capable of offering high resolution images in conditions ranging from bright day light, fog/haze, twilight and dusk. Lens focal lengths include two 25 mm designs, a 35 mm and a 50 mm design. The new SWIR lenses are constructed for rugged environments and come standard with thumb screws for locking the focus and iris functions. Designed to cover 1 (16 mm diagonal) sensors, the lenses offer high resolution images and transmission in the 7001,900nm wavelength of 75% or better. These lenses are ideal for a variety of imaging applications where SWIR cameras are employed, such as perimeter surveillance, food sorting, toll-way monitoring, border and port security, quality control or aerial imaging.
