UQG Optics

Sheet Glasses – Technical – Industrial – Scientific
UQG custom made range of sheet glasses includes all glasses with polished surfaces as supplied by the manufacture. These are more suited for industrial, commercial, scientific and for less optically demanding applications. The quality of the surfaces of these materials, has greatly improved over the years as technology has advanced to produce highly transparent polished surfaces. Excellent flatness and parallelism but economical enough for commercial and precision applications in a range of edge finishes.

UQG custom cut windows and plates from these sheet glasses to various sizes and shapes. Glasses include the following types in standard thicknesses made in small and production qualities.
