Description

1 11967912

The invention relates to a device of 2 mm, and a film of cobalt aluminate.

you, designed to filter () a thickness of 1 micron optical radiation.

The purpose of the invention is the improvement of high hardness and chemical

resistance to high-temperature-5 resistance to acids and alkalis

wet and corrosive environments ensure surface stability

as well as mechanical strength. the proposed filter to mechanical

The drawing shows the spectral and chemical effects, and the dysharacteristics of the optical filter, the high melting points of corundum and

consisting of a substrate made, 10 spinel allow to use it

of leucosapphire (), .thicker under high temperature conditions.
