CHESHAM, England, Dec. 1, 2010 — The Model 305 fixed-focus nonbrowning lens from Resolve Optics Ltd. has been designed to provide high performance with large image format cameras and sensors used in environments subject to radiation. Measuring only 30 mm in diameter, the compact f/2 lens delivers high image resolution and minimum geometric distortion from 400 to 750 nm. Manufactured from cerium-doped glass or synthetic silica, the lens can withstand radiation exposure of up to 53 kGy (108 rads) and temperatures up to 55 °C without discoloration. Designed to yield a 40° field of view in both the vertical and horizontal planes and to deliver 25 cycles per millimeter, it provides good optical performance for images up to 18 mm in diameter. Available with a manual or motorized iris, the lens offers a focus from 35 mm in front of the lens to infinity. It meets the requirement of nuclear vision and space research applications for cameras to be radiation-hard and to cover a large image format.
