The Model 290 Motorised Non-Browning Zoom Lens from Resolve Optics has a range of features to assist operation in environments subject to radiation.
These include nuclear fuel-handling operations, reactor active zones and nuclear-waste storage plants.
Developed as a direct replacement to the no-longer manufactured Fujinon 12-72mm (6x) non-browning zoom lens, the Model 290 uses special glass that can withstand long-term exposure to high levels of radiation (up to a total dose of 100,000,000 rads) and temperature (55C) without discoloration.
All functions of the Model 290 are motorised and include slip clutches and electronic noise suppression.
Operating at f/1.8, the Model 290 provides high image-resolution and minimum geometric distortion from 400 - 750nm.
The novel design provides a six-fold zoom movement in a very compact form.
This provides the lens with the capability to image objects from 800mm 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).
The high-performance Model 290 CCTV Zoom Lens has been designed for use with single-chip 0.5 and 0.66in CCTV cameras as well as Newvicon and Chalnicon tubes.
