Abstract
An optical device includes an optical assembly having a housing, a first end window, and a second end window. The first and second end window together with the housing provide an enclosed volume for a protected optical device including an optical material. A material for the end windows blocks essentially all non-pass band light having sufficient energy to generate absorption phenomena in the optical material while transmitting essentially all of operational wavelength light (pass band light) for the optical device. A material for the housing also blocks essentially all the non-pass band light from reaching the optical material.
