Abstract
An optical device for interacting with x-ray radiation, wherein the device includes an optical element configured for use as part of a spectroscopy tube, proportional counter, Geiger counter, optical detector or similar optical instrument. An exposed surface of the optical element is coated with at least one bonded layer of boron hydride composition to protect against abrasion, corrosion and other forms of degradation, as well as to provide enhanced sealing of the Z material against leakage. Methods of bonding the desired coating to the optical element are also disclosed.
