Camera Inspection in High Radiation Nuclear Environments

The nuclear industry needs lenses and optical systems that can cope with being exposed to high levels of radiation and may be required to endure high temperatures.

Resolve Optics Ltd has strong experience in producing lenses and optical systems for applications in challenging industrial environments that may be hard to access.

Non-Browning Lenses

The Resolve Optics team has provided high performance optical systems to some of the most prominent organizations in the nuclear industry. These solutions include resistant to radiation or 'non-browning' lenses (zoom and focus), remote inspection systems, and through-wall endoscopes.

An example of this was a variation of Resolve Optics’ Model 357 non-browning zoom lens engineered for DEKRA Visatec GmbH to be used in their VT XLRAD-10 PTZ camera, allowing the company to provide an effective new system for inspection in radioactive enviroments.

Compact Inspection Camera System

The new compact inspection camera system has been verified through investigations to provide superior image quality and allows the user to capture close-up images in environments with high radiation.

DEKRA Visatec has been a leader of innovation in the non-destructive visual testing industry for more than 20 years. DEKRA Visatec inspection camera systems are utilized by a number of the leading nuclear organizations internationally.

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.

Marcus Jocham, Business Development Manager, DEKRA Visatec

Mr Jocham added, “Combining remote control of lens functions with true high definition quality images, over a 10x 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.

Sharp and Clear Images

The Model 357 utilizes specifically chosen non-browning glass, which allows it to take sharp and clear images that are free of the strong yellow tint that has been a challenging issue when employing radiation resistant lenses on color sensors in the past.

The non-browning glass utilized in the Model 357 has been verified to cope with long-term exposure to temperatures up to 55 °C without discoloration and radiation up to a dose of 100,000,000 radians.

Functioning at f/3.6, the 2/3-inch format Model 357 offers optimal image resolution and reduced geometric distortion from 400 to 770 nm, and can image objects from 1.5 meters to infinity without the need for add-on adapters being used.

The lens attains a high image resolution at full aperture across the zoom range with no refocusing when focused at infinity.


Resolve Optics draws upon almost 30 years of experience when finding solutions for its clients.

It has built a trustworthy reputation for specialist lens design and the creation of smaller production quantities of radiation-resistant (non-browning) lenses and optical products, created on schedule to the tight target price and quality guidelines.

Contact Resolve Optics now to evaluate any application and to discover more about the refined optical design and manufacturing solutions that it can provide for use in the Nuclear Industry.
