Laser alignment tool from Pinpoint Laser Systems uses a pentaprism
The 90-Line-D is an industrial tool for aligning and checking planar squareness and parallelism on assemblies, machinery, and equipment. With wired and wireless versions available, the laser alignment tool uses a pentaprism to form a laser plane for alignment and measurements. A built-in detector actively corrects for any misalignments or small errors.
