First of all, I'd like to mention how awesome this forum is, there's a fantastic amount of information to be found here.
I've recently been sucked in to the awesome world of lasers, and I'm planning on building some 100mW+ lasers soon. Before I do so, I'd like to get my goggle situation squared away first.
I've been doing a lot of reading here (and other places, like the Laser Bible), and I'd just like to clarify what I've been reading, to make sure I understand what I'm doing. Yes, I know what the search function is and I'm capable of using it. I'm simply asking for confirmation, as most of the things I've read don't directly apply to the lasers I will be making and using.
First off, I understand I will need goggles for any laser over 5mW. I recently received a "30mW" 405nm pointer from eBay, and I'm hesitant to point it at anything but the sky right now. I have no way of knowing its actual power, but it says 30mW on it, hence the quotes. Am I safe looking at the spot if it's only pointed at non-reflective surfaces, such as carpeting and matte paint?
Second, I'd like to make sure these two goggles are the correct ones I will need for the lasers I plan to build. I'm going to make a 100mW 405nm, a 100mW 532nm, and a 200mW 650nm. To look at the dot from these, even on matte surfaces, I'm sure I'll need goggles.
I'm looking at these two pairs of goggles from OEM Laser Systems:
KRY - UV, KTP, 190-579nm Protection KRY - UV, KTP, 190-579nm Protection [NR-KRY-00FDA] - $98.60
KRR - UV, Red, Visible Diode, Ruby Protection KRR - UV, Red, Visible Diode, Ruby Protection [NR-KRR-00FDA] - $98.60
Is there anything I'm missing? I apologize if I'm posting dumb questions, but I'd much rather be flamed now than lose my eyesight later because I was afraid to ask and overlooked something.
