CHESHAM, UK, Feb. 26, 2010 – The Model 290 motorized non-browning zoom lens from Resolve Optics Ltd. operates in environments subject to radiation, such as nuclear fuel handling, reactor active zones and nuclear waste storage plants. It uses special glass that can withstand long-term exposure to radiation up to a dose of 100,000,000 radians and temperatures to 55 °C without discoloration. The 6× lens features slip clutches and electronic noise suppression.

Operating at f/1.8, it provides high image resolution and minimum geometric distortion from 400 to 750 nm, and it can image objects from 800 mm to infinity without using 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).

It is designed for use with single-chip ½- and ?-in. CCTV cameras and with Newvicon and Chalnicon tubes.
