A variant of Resolve Optics Model 357 non-browning zoom lens was developed for DEKRA Visatec VT XLRAD-10 PTZ camera, which enables them to offer a powerful radiation resistant inspection system.
This compact inspection camera system has proven in testing to offer amazing image quality and the possibility for close up pictures in high radiation environments.
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 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 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.
