Resolve Optics reports on growing demand for radiation resistant fixed focus and zoom lenses for CCTV cameras used for visual inspection in nuclear power stations.
Following on from the widely reported accidents at Chernobyl, and more recently the Fukushima Daiichi nuclear power plants, the need for CCTV camera systems that can operate even when subject to high radiation was clear. Bringing its expertise in radiation resistant lenses, Resolve Optics is a world leader in the supply of key camera lenses used in applications including the inspection of fuel elements, pressure vessels and nuclear cores, as well as the inspection of loading and offloading of nuclear materials.
All optical elements in Resolve Optics radiation-resistant lens designs for CCTV cameras are made using cerium oxide-doped glass or synthetic silica. This allows the fixed focus and zoom camera lenses to withstand radiation doses up to 1 billion rads and temperatures up to 100°C without significant discoloration or performance degradation. These specialist lenses also provide high image resolution and minimum geometric distortion from 400 to 750 nm.
