Motorised zoom lens won't go brown
Zoom lens incorporates a range of useful features to assist operation in environments subject to radiation such as nuclear power generation stations.
New from Resolve Optics, the Model 290 motorised nonbrowning CCTV zoom lens incorporates a range of useful features to assist operation in environments subject to radiation such as nuclear power generation stations The compact 6x optical tracking zoom uses special glass that can withstand long term exposure to high levels of radiation (up to a total dose of 100,000,000 rad) and temperature (55C) without discolouration

Adapter expands the field of view
A novel high performance 0.5x wide angle adapter is designed to provide a true 0.5x field of view while maintaining minimal distortion and high resolution throughout the zoom range of the camera.
Miniature zoom lenses get up close
A new range of miniature f/2.8 colour zoom lenses match the resolution offered by high quality colour CCTV cameras.
All three functions of the Model 290 are motorised and include slip clutches and electronic noise suppression which enables the 290 to be used as a direct replacement for the Fujinon 12-72mm (6x) non browning zoom lens.
Operating at f/1.8 for most focal lengths the lens provides high image resolution and minimum geometric distortion from 400-750nm.
The high-performance Model 290 CCTV zoom lens has been designed for use with single chip half- and two-thirds-inch CCTV cameras as well as Newvicon and Chalnicon tubes.
Typical monitoring applications for the Model 290 will include nuclear fuel handling operations, reactor active zones and nuclear waste storage plants.
By using a novel telescopic focusing mount the lens gives a large movement in an extremely compact form.
This provides the lens with the capability to image objects from 800mm to infinity without using addon 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 Model 290 6x CCTV zoom lens is part of a growing range of high performance radiation resistant lenses from Resolve Optics.
In keeping with Resolve Optics tradition of designing unique lenses, the company is also able to provide nonbrowning lens to meet exact customer specifications. Request a free brochure from Resolve Optics ...
