    Product Description

    157-111 Mitutoyo Optical Parallel: .5125"

    The Mitutoyo 157-111 optical parallel has the following specifications:

    • Thickness: .5125"
    • Range of Micrometer to be Checked: 0-1"
    • Diameter: 1.18"

    Features:

    • Designed to inspect parallelism and flatness of measuring faces of micrometers
    • Optical parallels are offered as individual or as sets.  Each set consists for 4 different thickness optical parallels. 
    • Supplied in fitted wooden case.

    Technical Data

    • Flatness: 0.1�m / .000004"
    • Parallelism: 0.2�m / .000008"
    • Diameter: 30mm / 1.18"

    Parallelism check between measuring faces by means of interference fringe produced by an optical parallel.

    The parallelism between the measuring faces can be determined as follows:

    • Place the optical parallel to the anvil and observe the number of interference fringes produced on the spindle side under the measuring force of the micrometers.
    • The parallelism is about 1�m (0.32�m x 3 = 0.96�m).
    • Fringe on the anvil side must not be more than one.
