Resolve Optics Ltd. recently began offering high performance fixed focus radiation tolerant lenses that range from 6mm to 25mm focal length with fields of view up to 108 degrees.
Fixed focus can be a lower cost and more compact alternative to zoom lens. Since a fixed-focus lens requires no input from the operator, it is suitable for use in cameras and sensors designed to be less expensive, or to operate in environments where space is at a premium.
All Resolve Optics fixed focus radiation tolerant lenses provide high image resolution and minimum geometric distortion from 400 to 750nm. Resolve Optics range of high-performance fixed focus radiation tolerant lenses have been designed for use with 1/2", 2/3" and 1" CCTV cameras as well as Newvicon and Chalnicon tubes in a variety of nuclear monitoring applications.
All optical elements within Resolve Optics radiation tolerant fixed focus designs are made using cerium oxide doped glass or synthetic silica enabling them to withstand radiation doses of up to 100,000,000 rads without degradation of performance.
