Laser Pointer Forums - Discuss Laser Pointers | High Power Lasers

Hello everyone,

I've been thinking about building my own RGB lumia projector for quite a while. And when I found a super cheap 200mW RGB module on ebay (straight from China..) I couldn't resist. Now that it arrived I have some questions concerning safety.
First of all I am searching for some protective glasses that are suitable for all three wave lengths (532nm(30mW), 638nm(100mW), 445nm(100mW)). I found some IPL (Intense Pulsed Light) safety glasses with a wave length protection of 190-1800nm and OD4+. Now I am wondering if those glasses are good enough for working with lasers.

My second question is whether it is necessary to add additional safety features to the projector if I want to operate it on my living room table. I could imagine a motion sensor that shuts the laser down if somebody steps in front of it so that nobody can look into the beam accidentally.

And I am wondering if I should install an IR-filter in case that the green DPSS module is low quality.

Thanks in advance! :thanks:
