Close-up inspection system for high radiation environments
It has been announced that Resolve Optics has developed a varient of its Model 357 non-browning zoom lens to enable DEKRA Visatec to offer a compact, new radiation resistant inspection system. Based on their VT XLRAD-10 PTZ camera, fitted with the Model 357 zoom lens, the DEKRA Visatec inspection system has proven in testing to offer image quality and the possibility for close up pictures in high radiation environments.
Marcus Jocham, Business Development manager at DEKRA Visatec, said: “We chose to enter into a long term partnership with Resolve Optics because of their extraordinary technical support and pedigree in developing and supplying OEM quantities of top quality, high-performance radiation resistant lens.
“Combining remote control of lens functions with true high definition quality images, over a 10x zoom range, the motorised Model 357 lens enables our new camera system to set a new standard for safe, high quality inspection of hot cells and nuclear fuel rods.”
Managing Director of Resolve Optics, Mark Pontin, added: “We were extremely pleased to be selected by DEKRA Visatec to develop and supply the HD zoom lens that forms a vital part of their new radiation resistant inspection camera system.”
The Model 357 uses specially selected non-browning glass enabling it to produce clear sharp images free of the strong yellow tint that has traditionally been a limiting issue when using radiation resistant lenses on colour sensors. The non-browning glass used in the Model 357 is proven to withstand long-term exposure to radiation up to a dose of 100,000,000 radians and temperatures to 55°C without discolouration.
Operating at f/3.6, the 2/3-inch format Model 357 provides high image resolution and minimum geometric distortion from 400 to 770nm, and can image objects from 1.5 metres to infinity without using add-on adapters. When focused at infinity, the lens achieves high image resolution at full aperture throughout the zoom range without refocusing.
