Resolve Optics has launched a new 2/3-inch format motorised version of its Model 357 radiation-tolerant zoom lens.
Designed for use with colour 2/3 inch tube and CMOS cameras in high radiation environments, the Model 357-004 provides true HD quality images over a 10x (12-120mm) zoom range.
Rob Watkinson, customer support manager at Resolve Optics, said: “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 transmission loss”.
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 firm says. It adds that because the 357-004 is a tracking zoom lens, it will maintain focus throughout the entire zoom range once set up.
