CHESHAM, England, March 12, 2012 — Resolve Optics Ltd. has announced a longer focal length version (24 to 144 mm) of its Model 290 motorized radiation-resistant zoom lens.
Presenting the same compact footprint as the standard Model 290, the new range-extended 6× zoom lens allows users to get closer to the subject and renders images easier to read, without any loss of performance.
The lens enables users to image objects from 800 mm to infinity without the need for add-on adapters. When focused at infinity the lens achieves high image resolution on-axis at full aperture throughout the zoom range without refocusing (image tracking). Operating at f/1.8, the extended-range Model 290 provides high image resolution and minimum geometric distortion from 400 to 750 nm.
All optical elements in the nonbrowning zoom lenses are made using cerium oxide-doped glass or synthetic silica, enabling them to withstand radiation exposure of up to 53 million rads and temperatures up to 55 °C without discoloration.
