Radiation Resistant 6x Zoom Lens... The Model 290 Motorised Non-Browning Zoom Lens from Resolve Optics Ltd. incorporates a range of useful features to assist operation in environments subject to radiation such as nuclear fuel handling operations, reactor active zones and nuclear waste storage plants.Developed as a direct replacement to the no longer manufactured Fujinon 12-72mm (6x) non browning zoom lens the Model 290 uses special glass that can withstand long term exposure to high levels of radiation (up to a total dose of 100,000,000 rads) and temperature (55 °C) without discoloration. All functions of the Model 290 are motorised and include slip clutches and electronic noise suppression. Operating at f/1.8 the Model 290 provides high image resolution and minimum geometric distortion from 400 - 750 nm. The novel design provides a 6x zoom movement in a very compact form. This provides the lens with the capability to image objects from 800mm 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). The high-performance Model 290 CCTV Zoom Lens has been designed for use with single chip 1/2" and 2/3" CCTV cameras as well as Newvicon and Chalnicon tubes.
