Low-SWaP SWIR/NIR zoom lens for 5µm, 10µm SXGA detectors

The Ophir SWIR & NIR 25-250mm f/5.5 (NFOV) f/4.0 (WFOV) continuous zoom lens is a first to market low-Size, Weight, and Power (SWaP), compact lens, for the newly introduced 5μm SXGA, as well as for 10μm SXGA, and 15μm VGA SWIR detectors. The SWIR & NIR zoom lens employs a unique mechanical and optical design, resulting in an all-around smaller and lighter unit with only 860gr in weight, and 214mm in length, making it approximately 60% lighter than similar existing SWIR lenses. The SWIR lens is also chromatically corrected to support a broader short-wave IR wavelength regime from 0.7-1.7μm and operates with minimal distortion. The SWIR & NIR 25-250mm f/5.5 (NFOV) f/4.0 (WFOV) continuous zoom lens presents an unrivaled combination of SWaP capabilities, detection range exceeding 26km, rugged design, and a unique coating able to withstand harsh, humid, and salty environments.

SWIR & NIR 25-250mm f/5.5 (NFOV) f/4.0 (WFOV) Detection, Recognition & Identification (DRI) Range

DRI ranges enable one to easily estimate the maximum range that an object can be either detected, recognized or identified. It is important to note that these estimates are based solely on geometrical parameters – the target size, distance, lens focal length and camera detector pixel size. Signal level, detector sensitivity, atmospheric conditions and other factors are not considered!

The calculations used here are based on the “Johnson Criteria”. According to the Johnson Criteria, the minimum resolution, pixels on target, required to achieve a 50% probability for an observer to discriminate an object are:

Detection: An object is present – 2 pixels on target (Lower Bar)
Recognition: discern the type of object, a human vs. a vehicle – 8 pixels on target (Middle Bar)
Identification: discern specific objects, a man vs. a woman, a car model – 12.8 pixels on target (Upper Bar)
