The Model 192 uses special glass that can withstand long-term exposure to radiation up to a dose of 100 million radians and temperatures to 55°C without discoloration. Operating at f / 1.8, it provides high image resolution and minimum geometric distortion from 400 to 750nm, and it can image objects from 800 mm 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. It is designed for use with 1/2- and 2/3-inch CCTV cameras and with Newvicon and Chalnicon tubes.
All optical elements within Resolve Optics radiation resistant (non-browning) lens designs are made using cerium oxide doped glass or synthetic silica enabling them to withstand radiation doses of up to 100,000,000 rads and temperatures up to 55°C without discoloration or degradation of performance. All Resolve Optics radiation resistant lenses provide high image resolution and minimum geometric distortion from 400 to 750nm.
