Hey all.

Anyway, had a question, I'm working on building an etching laser and want to have a visible red 5mw laser to serve as a guide, then switch to the IR laser for etching.

Ideally id like the opposite of a beam splitter. Basically shooting a red laser from one side, then switching to the IR laser aimed at the other side. The idea is that the red laser would travel the exact same path as the IR laser.

I figure there has to be a prism or something for this but maybe a beam splitter in reverse would work?
