Direct laser beams where you need them with components that turn or split your beam. They work with any dot laser.

90° beam splitter converts a single dot into two dots; one continues in a straight line, the other projects at a 90° angle. The splitter screws into a standoff.

Dot-to-line converter requires a holder to mount to a standoff.

Standoffs have 8-32 male threads on one end and 1/4"-20 female threads on the other. Diameter is 1/2". For additional lengths, see 18-8 Stainless Steel Standoffs.
