Hello Folks,
I would like some advice on laser safety. I am trying to build an XY table, with a laser to do some engraving on substrate. The lasers I plan to experiment on will probably be Blue Ray (404 nM, 100 mW) and IR (808 nM, 300 mW). I intend to do all the tuning etc with a (relatively) harmless 5 mW red laser pointer, then swith to the more powerful lasers. I would like some advice on eye safety, because there is no way I want to risk my eyesight.
I guess I should get some laser goggles which block several laser wavelenghts instead of just one - so I can still use my goggles even if I change laser frequency. So something that blocks below blue and above Red sounds good...
Laser Glasses - YAG Harmonics DIODE - Poly Filter
these block 190-534nm and 730-1090nm at OD>5.
The issue is of course the cost - these are expensive at over 250 USD... very steep for a hobby, but very cheap for protecting my eyeballs...
Would you recommend any other suppliers, a cheaper brand? There are plenty of cheaper goggles on eBay, but I am not sure about the reliability and the quality... these "look" okay, but I have no means to test them...
