Based upon a proven design – Resolve Optics new Model 192-001 non-browning six times zoom lens offers high performance over an extended 24 to 144mm focal length range making it perfect for remote monitoring tasks in nuclear reprocessing and power plants.

The compact lens’s speciality glass components can withstand long-term exposure to radiation, up to a dose of 100 million RAD and without loss of transmission and minimal colour change. Operating at f/3.6, the Model 192-001 provides good image resolution and minimum geometric distortion from 400 to 750 nm. When focused at infinity, the Model 192-001 will maintain focus throughout the zoom range without the need to refocus.

Available in 1/2" and 2/3” image formats the C-mounted Model 192-001 can be simply mounted on Newvicon tubes, Chalnicon tubes and CCD devices.

Nuclear industry applications require lenses and optical systems that can withstand exposure to high levels of radiation and sometimes endure extreme temperatures. Resolve Optics has considerable experience of developing lenses and optical systems for applications in hazardous or difficult to access industrial environments.

The Resolve Optics team has worked with leading companies in the nuclear industry to provide radiation-resistant, high performance solutions including non-browning lenses (fixed focus and zoom), through-wall endoscopes as well as vision and remote inspection camera systems.
