A new high performance 12-72mm nonbrowning zoom lens (192-000) incorporates a range of useful features to assist operation in environments subject to radiation.
Resolve Optics has released a new high performance 12-72mm nonbrowning zoom lens (192-000) that incorporates a range of useful features to assist operation in environments subject to radiation.
The compact x6 optical tracking zoom uses special glass that can withstand long term exposure to high levels of radiation (up to a total dose of 108rads) and temperature (55C) without discolouration.
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 192-000 lens has been designed for use with single-chip half- and two-thirds-inch CCTV cameras as well as Newvicon and Chalnicon tubes in a variety of monitoring applications including nuclear fuel handling operations, reactor active zones, nuclear waste storage plants, food irradiation processes and radiation crosslinking of polymers.
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 192-000 nonbrowning 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 lenses to meet exact customer specifications.
