Resolve Optics provides the Model 290 as a motorised 6x non-browning zoom lens with a range of mechanical options to optimally suit different applications that may be subject to radiation.
The Model 290 is a versatile non-browning zoom lens that is widely used in nuclear fuel handling operation, reactor active zones and radioactive waste storage plants. For applications where space is limited the version of the Model 290 with concentric motor is recommended. In environments subject to electronic interference a version of the Model 290 is available with noise suppression to minimise degradation of optical performance.
Zoom, focus and iris movements on the Model 290 are motorised
Employing special cerium doped glass elements, the Model 290 can withstand long term exposure to high levels of radiation (up to a total dose of 100,000,000 rad) and temperature (55 °C) without loss of transmission. Zoom, focus and iris movements on the Model 290 are motorised using radiation-tolerant DC-motors to facilitate remote operation in hazardous environments. Operating at f/1.8 the Model 290 provides high image resolution and minimum geometric distortion throughout the spectral region 400-750nm. The Model 290 is optimised for use with single chip 1/2" and 2/3" CCTV cameras as well as Newvicon and Chalnicon tubes.
