Squareness/Perpendicularity

For squareness or perpendicularity measuring, the laser beam is redirected with an optical device called a 90-Line. By redirecting the laser beam at precisely 90 degrees off an established path, many additional measurements and alignments are possible.

Common applications include:

• Squaring machinery and equipment
• Aligning the Z axis of machine tools
• Belt, gear and sheave alignment
• Checking parallelism of tracks and assemblies
• Aligning gantry rails and cross bridges
• Squaring machine guides and pallet loaders
• Adjusting moving actuators and drilling systems
• Squaring stacked linear stages
• Adjusting slitters, idlers and rollers
• Squaring cross cutting systems and guides
• And many other geometric alignment needs

How Do You Do It?

The 90-Line is placed into the laser beam path and redirects the laser beam off at a precise right angle from the original laser beam. The 90-Line has an internal optical element called a penta-prism that reflects the laser at precisely 90 degrees to the incoming laser beam, regardless of the orientation of the 90-Line housing. Measurements are made by first aligning the laser to a central machine axis or along a reference path. Placing the 90-Line into the laser path redirects the laser beam off at a right angle so that other assemblies can be positioned and aligned squarely to the original laser path. The nosepiece of the 90-Line will also turn so that you can direct the laser through a full plane that is perpendicular to the the original laser path. Several 90-Lines can be used in combination to redirect the laser around an alignment area.

What is Needed?

• Laser Microgage 2D or 2000
• 90-Line Right Angle
