37987" Diameter, 1/2" Thick, Parallel Surface Optical Flat MPN:3200833

Parallel surface optical flat 37987 diameter inch thick is an essential tool for highly precise dimensional measurements of thin films or substrates in optical, semiconductor and other related industries which require extreme flatness on one or both surfaces. The smooth polished surfaces guarantee minimal reflection ensuring high-quality results while measuring the flatness or parallelism of objects during manufacturing or quality control procedures using interferometry techniques. Additionally, it can be used for testing the parallelism and squareness between two flats surfaces or parts with micrometer precision during assembly and fabrication processes in precision instrumentation such as lens, mirrors or prisms.
