2/3” zoom lens for high radiation environments

Purpose designed for use with colour 2/3” tube and CMOS cameras in high radiation environments, the Model 357-004 provides HD quality images over an unrivalled 10x (12–120mm) zoom range. 

Rob Watkinson, Customer Support Manager at Resolve Optics, commented: “The Model 357-004 was developed to provide better HD colour images for the nuclear industry. Offering full motorised control of zoom, iris and focusing this robust lens is easily integrated with most nuclear cameras and sensors.”

He added: “The Model 357-004 zoom lens uses specialised non browning glasses to produce clear sharp images free of the strong yellow tint that has traditionally been a limiting issue when using radiation tolerant lenses on colour sensors. The glass used in these lenses can withstand long-term exposure to radiation up to an accumulative dose of one hundred million RAD and temperatures up to 85°C without loss of transmission.”

Operating at f/3.6, the Model 357-004 zoom lens provides high image resolution and minimum geometric distortion from 400 to 770nm and can image objects from 1300mm to infinity. The 357-004 is a tracking zoom lens, meaning that once it has been set up, it will maintain focus throughout the entire zoom range.
