Optical Substrates
Optical substrates cover a broad range of material types and specification. Widely used in imaging, instrumentation, spectroscopy, thinfilm and optoelectronic applications.
Optical substrates are made from technical glass materials and optical materials including fused silica and quartz glass with these surfaces optically polished.
High precision optically polished substrates for laser applications are polished to a surface finish of 10/5 scratch dig with a tight specification on flatness and parallelism.
Precision optical substrates polished to a high surface finish at 20/10 are better are used in graticule and peticule manufacture.
Spectrotopic optical substrates are twin lapped and polished using a double sided twin planetary process achieving a high quality surface with production running to high oem volume manufacture. The surface finish is generally a 60/40 or 80/50 scratch dig with a general specification for flatness and parallelism.
Optical substrates not mechanically optically polished and in the form of sheet glass materials are cut and ground from a range of technical glasses. See materials page for full range and custom page for processing.
