Self-aligning laser alignment tool

Description

These alignment tools are designed to be placed into the holes of an optics table ensuring the beam is aligned along the screw holes. A movable aperture can be adjusted to set a consistent beam height with either 5mm or 1/4" increments. A nut can be attached to the small post on the back side to prevent the alignment tool from falling over while in use.The "Canadian" post is designed for aligning metric beam heights above an optical table with imperial (1") hole spacing. Make sure you download the correct aperture for your post. The metric aperture is not compatible with the imperial post and vice-versa.
