Taking Close-Up Pictures in High Radiation Environments

A variant of Resolve Optics’ Model 357 non-browning zoom lens has been developed for DEKRA Visatec GmbH for use on its VT XLRAD-10 PTZ camera, allowing a powerful new radiation-resistant inspection system to be offered.

Testing proved that the new compact inspection camera system offers excellent image quality and the potential for close-up pictures in high-radiation environments.

For over twenty years, DEKRA Visatec (www.dekra-visatec.com) has been at the forefront of innovation in the non-destructive visual testing market. DEKRA Visatec inspection camera systems are employed by many of the world’s leading nuclear organizations.

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.

The Model 357 uses specially selected non-browning glass, allowing it to produce clear, sharp images free from the strong yellow tint that has traditionally impeded the use of radiation-resistant lenses on color sensors. The non-browning glass used in Model 357 can withstand long-term radiation exposure up to a dose of 100,000,000 rad and temperatures of up to 55 °C without discoloration.

Operating at f/3.6, the 2/3 inch format Model 357 provides high image resolution and minimum geometric distortion from 400 to 770 nm and can image objects from 1.5 meters 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.

Drawing on nearly thirty years of experience, Resolve Optics has a strong reputation for specialist lens design, as well as the efficient manufacturing of smaller production quantities of radiation-resistant (non-browning) lenses and optical products in adherence to strict quality and target price guidelines.
