This is a highly precise dial gauge that uses optical interference so you can measure with unparallelled accuracy.
The Mitutoyo Laser Hologage offers you the following benefits:
• Through optical interference of laser light through a diffraction grating it gives you an extremely precise holographic scale with 0.00001mm resolution.
• You can use the Laser Hologage for extremely precise measurements, as well as a transducer in ultra-precise positioning and control systems.
