Close-Up Imaging in High Radiation Environment

A variant of Resolve Optics’ popular Model 357 non-browning zoom lens created for DEKRA Visatec GmbH is used on its VT XLRAD-10 PTZ camera. It allows DEKRA Visatec GmbH to provide a robust new radiation-resistant inspection system.

In testing, the new compact inspection camera system demonstrated exceptional image quality and the ability to take close-up images in high radiation settings.

DEKRA Visatec has been at the forefront of advancements in non-destructive visual testing for over 20 years. Several of the world’s leading nuclear organizations employ DEKRA Visatec inspection camera systems.

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 10 × zoom range, the motorized 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.

Model 357

The Model 357 employs specifically selected non-browning glass to create bright, sharp images free of the strong yellow tint that has conventionally been a limitation when using radiation-resistant lenses on color sensors.

The non-browning glass utilized in the Model 357 can survive long-term radiation exposure up to a dose of 100,000,000 rad and temperatures up to 55 °C without discoloration.

The 2/3-inch format Model 357, which operates at f/3.6, delivers high image resolution and minimal geometric distortion from 400 to 770 nm and can image objects from 1.5 m to infinity without add-on adapters. The lens achieves great image resolution at maximum aperture across the zoom range when focused at infinity without refocusing.
