Technical Notes

Developing lenses that operate over a wide temperature range

A question we are often asked is ‘What is the operating temperature range of a particular lens”. As refractive index is a function of temperature, you could reasonably expect that a lens will experience some performance degradation with changing temperature.

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.
