Microgage – Squareness

About Squareness

Product# – PR-SQ21

The Microgage system works on a very simple principle: Laser light travels in a straight line. The Microgage system Squareness Kit comes with a 90-Line beam redirector which utilizes an internal optical element called a penta-prism that reflects the laser at precisely 90 degrees to the incoming laser beam. Squareness and perpendicularity measurements are made by first aligning the laser to a central machine axis or along a reference path and then redirecting the laser beam off at a right angle so that other assemblies can be positioned and aligned squarely to the original laser path.

The PRO series includes a smart display with touchscreen technology and can also be wireless. Pinpoint laser systems are simple, rugged and portable.
