The Mitutoyo optical parallels are constructed of optical-grade glass and can measure the parallelism and flatness of a micrometer’s measuring face.
Optical Flats
Features & Benefits
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. Our optical parallels are precision polished and lapped for exceptional flatness in our Japanese factories.
- Available in Metric or Inch sets
- 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
