Mitutoyo 157-903 Optical Parallel Set for Micrometers 0-25mm
The Mitutoyo optical parallels are constructed of optical-grade glass and can measure the parallelism and flatness of a micrometer’s measuring face. When used with monochromatic light, a Mitutoyo optical parallel can determine the measuring surface parallelism within 0.2µm/.000008in and flatness within 0.1µm/.000004in on micrometers. The Mitutoyo optical parallels are precision polished and lapped for exceptional flatness in Mitutoyo’s Japanese factories.

- Available in Metric or Inch (Sets or Individual)
- Each set consists of 4 optical parallels of varying thicknesses
- Constructed of highly polished, lapped optical-grade glass
