Radiation-Hard Lenses

The new Model 346 non-browning lens from Resolve Optics Ltd. (Chesham, UK) operates with color sensors in areas subject to radiation. The lens uses special glass that withstands long-term exposure to radiation up to a dose of 100 million radians and temperatures to 55°C without discoloration. Able to operate at f/2, the device provides minimum geometric distortion from 400 to 750 nm. Objects can be imaged from 50 mm to infinity without using add-on adapters. The Model 346 lens is designed for optimized use with 15-mm diagonal color CMOS sensors.
