An Effect of the Epoxy Cementing Technology on the Deformation of the Optical External Surfaces Made of Quartz Glass

Abstract:

The problematic issues, associated with deformations of the outer surfaces of optical parts made of quartz glass, due to the process of cementing, are considered. The effect of the heat treatment temperature of optical assemblies, consisting of parts made of quartz glass and cementing with epoxy cements OK-72FT₅ and OK-72FT_15, on the deformation of external surfaces was experimentally established. The object of the study was plane-convex and plane-concave lenses made of quartz glass. It has been stated, that on cementing with optical epoxy cements OK72FT₅ and OK72FT₁₅ the external quartz glass surface deformations depend primarily on the heat treatment temperature. When cementing parts are made of quartz glass, increasing the polymerization temperature improves the performance characteristics of products and reduces changes in their optical characteristics.
