We have studied experimentally, by using a differential interferometric technique, the effect of proton radiation on the refractive index of commercial (Schott) silicate crown glasses, BK7 and LaK9, and their radiation-resistant counterparts. The strongest effect was observed for the radiation-hard lanthanum crown LaK9G15: At a 0.65-Mrad dose the index change was approximately 3 x 10(-5). Radiation-hard glasses are used in optical systems operating in radiation environments because they prevent… Expand
Gamma radiation-induced refractive index change in Ge- and N-doped silica
We measured the change of the refractive index over a wide wavelength range in Ge- and N-doped high purity (fiber optics grade) silica glasses subjected to gamma irradiation. The radiation-inducedExpand

Rad-hard properties of the optical glass adopted for the PLATO space telescope refractive components.
TLDR
A model to simulate the throughput of the whole instrument has been developed and used to verify the instrument performance considering different stellar spectra, and describes the transmission loss as a function of the thickness in dependence of the impinging dose. Expand
