Channel Systems Inc. has placed an order with
Ltd
to supply a new lightweight version of the 80-200mm focal length UV Zoom lens
developed for use with their Digital Cerenkov Viewing Device (DCVD).
Spent nuclear fuel emits a faint ultraviolet Cerenkov light when gamma rays
from fuel assemblies interact with electrons in the cooling pond water.
The DCVD equipped with UV Zoom lens provides a highly-effective system that
captures the Cerenkov image of spent fuel for analysis and comparison. This
unique system provides inspectors with an effective tool for non-intrusive
verification of spent nuclear fuel.
The DCVD UV Zoom lens is wavelength-corrected to view a nuclear fuel assembly
situated 13 metres away from the lens and through 10 metres of water. To meet
the challenges of the application the UV Zoom lens is able to optimally operate
from 10 to 55ºC. Miniature motors allow accurate remote setting of both
zoom and focus functions. A filter slide was incorporated in the design
enabling the lens to be switched between UV (270 to 350 nm) and visible (400 to
700 nm) without the need to refocus the lens. By using a telescopic focus
the lens is able to image objects from 3m to infinity. The lens achieves
high image resolution with low distortion throughout the zoom range without
refocusing. A lockable C mount ensures the lens cannot come loose during
operation.
