The Nocpix RICO LRF 640×512 75 mm is a long-range LWIR thermal weapon sight built around a high-resolution 640×512 thermal sensor paired with a large 75 mm germanium objective for extended detection and identification ranges. It typically combines a bright microdisplay, onboard laser rangefinder, multiple ballistic reticles/profiles, digital zoom, and video recording/output for situational awareness and documentation. The 75 mm objective tightens the field of view relative to 50 mm variants, improving long-range target contrast and effective ID ranges at the expense of a narrower FOV and larger overall size/weight. With LWIR spectral sensitivity (7.5–13.5 µm) and a NETD in the low-tens of millikelvin, this class of sight is optimized for dawn/dusk, through-light-obscurants, and low-visibility detection tasks. Because I don’t have the official spec sheet open here, please confirm exact display resolution, FOV, NETD, dimensions and mass with Nocpix or your dealer before final purchase or system integration.
