The Spectro XR<sup>TM</sup> is an advanced color/NIR/SWIR/MWIR 16’’ payload recently developed by Elbit Systems / ELOP.
The payload’s primary sensor is a spotter camera with common 7’’ aperture. The sensor suite includes also MWIR
zoom, EO zoom, laser designator or rangefinder, laser pointer / illuminator and laser spot tracker. Rigid structure,
vibration damping and 4-axes gimbals enable high level of line-of-sight stabilization. The payload’s list of features
include multi-target video tracker, precise boresight, strap-on IMU, embedded moving map, geodetic calculations suite,
and image fusion.
The paper describes main technical characteristics of the spotter camera. Visible-quality, all-metal front catadioptric
telescope maintains optical performance in wide range of environmental conditions. High-efficiency coatings separate
the incoming light into EO, SWIR and MWIR band channels. Both EO and SWIR bands have dual FOV and 3 spectral
filters each. Several variants of focal plane array formats are supported.<p> </p>
The common aperture design facilitates superior DRI performance in EO and SWIR, in comparison to the
conventionally configured payloads. Special spectral calibration and color correction extend the effective range of color
imaging. An advanced CMOS FPA and low F-number of the optics facilitate low light performance. SWIR band
provides further atmospheric penetration, as well as see-spot capability at especially long ranges, due to asynchronous
pulse detection. MWIR band has good sharpness in the entire field-of-view and (with full HD FPA) delivers amount of
detail far exceeding one of VGA-equipped FLIRs.<p> </p>
The Spectro XR offers level of performance typically associated with larger and heavier payloads.
