Close-up inspection system for 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.
