    Product Description

    542-925A Laser Hologage Series 542: 4"/10mm

    The 542-925A has an accuracy of 0.1um.


    • The Mitutoyo Laser Hologage is a high-end digital gaging system that employs diffracted laser beam interference to make highly accurate and repeatable measurements. It features ultra-fine diffraction gratings which are holographically recorded on the scale. The Laser Hologage is suitable for measuring ultra-high precision parts, especially those in semiconductor and related industries.
    • Highly accurate measurement due to an ultra-high resolution of 0.00001mm (0.01um), which is close to the performance of laser interferometers.
    • Excellent measuring stability € the design is also highly resistant to unfavorable environmental conditions such as air movement and atmospheric pressure changes.
    • High-precision linear ball bearings are used in the guide for extremely smooth movement and exceptional durability.
    • A display unit is provided.
