The Topaz Series offers lightweight, high-performance LWIR imaging solutions optimized for 640 × 480 × 17 µm uncooled detectors in the 8–12 µm spectral range. Available in 18–60 mm F/1.4 continuous zoom and 22/66 mm F/1.25 dual field-of-view configurations, Topaz lenses deliver exceptional thermal sensitivity and minimal boresight error in compact, motorized designs. Engineered for 4″ gimbal payloads and space-constrained platforms, the series provides stable focus, fast zoom response, and rugged reliability under harsh environmental conditions. With low F-numbers, AR-coated optics, and IP66/67 sealing, Topaz lenses are ideal for UAV, handheld, and mobile thermal imaging systems that require precision, sensitivity, and compact form factor.
