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. 542-720D Laser Hologage supplied with Display Unit (2 axis counter) No. Range [mm] Accuracy Measuring force Resolution [μm] Stem ∅ Repeatability Mass [g] 542-720D 0 - 10 0,1μm 0,65 N with spindle down, 0,55 N spindle horizontal, 0,45 N spindle upwards 0,005 15 mm 0,02 μm 220 542-721D 0 - 10 0,1μm 0,1 N with spindle down/ - / - 0,005 15 mm 0,02 μm 220 *1 Spindle DOWN/Horizontal/UP 45.4 85 146 25 10 10 20 ø15h6 18 40 0 -0.011 All products to be sold to commercial customers.
