Features:
- Each set of parallels consists of 4 thicknesses
- Constructed of highly polished, lapped optical-grade glass
- Inspects the flatness of metal, ceramic and other materials
- Supplied in a fitted wooden case
When used with a monochromatic light, a Mitutoyo optical parallel can determine the measuring surface parallelism within 0.2µm/.000008″ and flatness within 0.1µm/.000004″ on micrometers. Optical parallels are precision polished and lapped for exceptional flatness in Japanese factories.
