Re: GB oemlasersystems goggles
Yes, they'll protect up to 5W of red with their OD3+. I chose the RB2 over others because I prefer the higher VLT. There are ones that'll protect you better such as the KRR (OD5+), but they have lower VLT. The KRR is also ~$20 cheaper. I just prefer higher VLT, even at the expense of some reduction in protection.
Yeah, they sure can add up. Perhaps get some strictly for working solo, and others in case you want other people to observe the lasers too. I only have a second pair of ML7s for a guest, but they're rarely used, and I haven't bought any secondaries for the other goggles. I'm glad to have the second pair for the "general purpose" pair of goggles (ML7) in case someone needs to help me out, shut something off, or just to enter the room to get to the safe location to see something (the goggles are to block matte reflections). Still, I think only one second pair is enough, at least for me.
I'm not sure how well those Eagle goggles perform. Many goggles have that "OD" rating, but how or who tested it, is rarely known (hence why we get laser protection certified goggles). I have some other anti-red laser goggles, but I just don't know or trust them; they just sit around unused. They may be good for blocking matte reflections from Class 4 lasers, but not a direct hit. Those "radiant shields" are supposedly tested, but I don't know if they cover red.
For reference, you can compute the power reduction from the OD rating:
Input power * 10^(-P) = Output power
Where P is the OD rating. You need to have the output power below 5mW to be safe, though you'll want it less to be comfortable (1mW is usually good, or even far less).
I only mention getting some goggles for red because after you get a green laser, you will probably want to make a red or blue (blue will be covered by the DBD). The greens get kind of "boring" since you are dependent on some pre-fabbed module, rather than being able to use diode-lasers too, not to mention getting higher powered greens is expensive.
The reds are just recently coming into their own now too, with those M!tsubishi laser diodes easily going over 500mW for dirt cheap. If you're going to do beam combining/RGB it's also very nice to have all wavelengths covered. You can always buy the goggles direct some other time, but you won't get that 25% discount.
You can order any pair of goggles that OEM sells even those solid metal ones. The goggles in that list are just what some people have decided on ordering, and what you'd expect to pay after the 25% discount. The 25% is for any and all goggles placed through OEM in this GB.
The KRY has a VLT of 10% which makes it hard to see. You might do better with an ARG instead; they're also cheaper.
