The Diamond family spans from the compact 18–430 mm F/5.5 base lens to the Diamond+ Beam Extender variants—30–600 mm, 40–860 mm, and 45–1075 mm (all F/5.5)—which extend focal length for true ultra-long-range MWIR imaging without sacrificing focus or alignment through the zoom. Designed for 640×512×15 µm cooled detectors in the 3–5 µm band, Diamond lenses deliver very high optical zoom ratios, fast motorized zoom/focus response, and rugged reliability with IP66/67 sealing and tight boresight retention—ideal for long-range surveillance, targeting, and border protection where distance and detail are critical.
