Features & Benefits

The Mitutoyo LGH Laser Hologage offers an extremely accurate, ultra-high-resolution photoelectric reflective linear encoder (0.01 models) or ultra-high-resolution laser interference (0.005 models) which provides superior performance over its entire measuring range of 10mm. Includes excellent measuring stability which resists unfavorable environmental conditions, such as, air movement and atmospheric pressure changes.

  • Range: 10mm (.4”)
  • LGH/counter bundles have switchable resolutions of: 5nm/0.005μm* (.1 μin*), 0.01μm (.5 μin), 0.1μm (5 μin), 0.5μm (20 μin), 1μm (50 μin)
  • Low measuring force models are available (542-716A, 542-721A) for measuring easily deformed workpieces or delicate films
  • Measurement data can be stored and controlled by PC software.
  • High precision linear ball bearings are used in the spindle guide for smooth movement and exceptional durability
  • Every LGH series gage is bundled with a dedicated counter
