I'm trying to build a basic beam expander. I am a commercial fisherman and I'm looking to build a prototype signaling device.
The idea is to use PVC and lenses salvaged from old optics I have laying around. I have done allot of searching and have read various articles, including some of the DIY threads on the forum.
But since I am a total noob, I have some possibly dumb questions.
Dumb Question:
I bought this 100mW green laser from Lazerer thinking it would fit inside a PVC housing well LZTN - 532nm 100mW Smallest Green Laser Pointer the laser does not focus.
Do I need to remove the lens from this Laser in order for it to work with my optics? In my initial tests with a Galilean expander design it seems I can only replicate a narrow beam not much bigger as its normal.
Also how concerned should I be with looking at the reflected dot of this laser at close range off a white wall? I do have eye protection, but I need to periodically take them off to see the results of my tests.
