Resolve Optics Ltd.Request Info
The Model 290 motorized nonbrowning zoom lens from Resolve Optics
Ltd. operates in applications subject to radiation, such as nuclear fuel handling,
reactor active zones and nuclear waste storage plants. It 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. The 6x lens features slip
clutches and electronic noise suppression. Operating at f/1.8, it provides high
image resolution and minimum geometric distortion from 400 to 750 nm, 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 (image tracking). It is designed for use with
single-chip 1/2- and 2/3-in. CCTV cameras and with Newvicon and Chalnicon tubes.
