Laser Hologage LGH-0510C-B-EH

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 0.005 µm resolution.
• The measuring head is very compact, enabling you to build it into various systems far less
  expensively than conventional laser technology.
• You can use the Laser Hologage for measuring extremely precise parts, as well as a transducer in ultra-precise positioning and control systems.
