Resolve Optics released the Model 357 range of non-browning zoom lenses designed for nuclear systems integrators to enhance the performance of their radiation tolerant monitoring systems. The Model 357 lens range provides true high definition quality images over a 10x zoom range. It is available in several formats such as 1/3-inch, 2/3-inch, or motorized, that deliver high performance imaging solution that can be used with most radiation tolerant cameras and sensors.
The non-browning glass used in Model 357 lenses can withstand long-term exposure to radiation up to a dose of 100,000,000 radians and temperatures to 55°C without discoloration. The lenses deliver high image resolution and minimum geometric distortion from 400 to 770 nm. They can image objects from 800 nm to infinity without using add-on adapters. When focused at infinity, the lens achieves high image resolution on axis at full aperture throughout the zoom range without refocusing.
