Cerium Stabilizes Optical Glasses against Transmittance Loss Caused by Ionizing Radiation

Resolve Optics Ltd has produced an informative technical note that addresses the question 'Does My Application Require Radiation Resistant Lenses?

In nuclear power, nuclear reprocessing, space, medical and other scientific applications optical glass may be exposed to high energy radiation like gamma, electron, proton and neutron radiation. With the accumulation of higher doses this radiation reduces the transmittance of optical glass (turning brown or grey) especially near the UV-visible edge of the spectrum.

Fortunately optical glasses can be stabilised against transmittance loss caused by ionizing radiation by adding Cerium (Ce) to the composition. The extent of stabilization differs from glass type to glass type.

Over the last 20 years - Resolve Optics Ltd. has established a strong international reputation as a leading supplier of fixed focus and zoom non-browning (radiation resistant) lenses. Drawing upon the same expertise - Resolve Optics has also developed a wide range of custom designed non browning lenses and radiation resistant endoscopes which enable areas with very high radiation to be viewed.
