Radiation-tolerant, fixed-focus lenses

Resolve Optics, a specialist in OEM lens design and manufacture, has introduced a selection of high performance fixed-focus radiation-tolerant lenses, ranging from 6 to 25mm focal length with fields of view up to 108°.

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, with minimum geometric distortion at wavelengths between 400 and 750nm. The range of lenses has been designed for use with 1/2-inch, 2/3-inch and 1-inch CCTV cameras, as well as with Newvicon and Chalnicon tubes in a variety of nuclear monitoring applications.

All optical elements within the lenses 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.
