Approach for getting goggles covering different wavelength

Hi, all.

For the last few days, I've been reading up the stickies and many posts for finding safety goggles. I figured in the end, instead of asking for just asking a specific model/names, I'd like to make sure my approach to the answer is sound. Please be so kind to bear with me...:bowdown::yh:


Here are my few criteria:

A) I only got a pair of eyes and intend to keep them regardless what. So I won't mind spending a good amount of money to cover all my angles. Probably even up to few hundreds or even more for certified/well-valued goggles.

B) Currently, all the lasers I owned are probably under 100mW, but I think my protective gear should be "forward-thinking", meaning I'd like to get as much protection to approximately 2W or even more, so my investment will last longer.



My questions:

With effort, I have narrowed down to two sites that I'd like to get my goggles from, either "OEM laser systems" or "laser safety industries"; since they both offer large size glasses that will fit over my large head with glasses.:crackup:


1) Anyone has owned those goggles or order from those sites, any complains(goggles/durability/shipping/etc)?


2) What OD is appropriate for a high power laser? Say we have a 532nm at 2W, what would be an appropriate OD for that?


3) I never use these goggles, so if I have OD 7 covering 532nm, what will I see through the goggle when a weak and strong green laser are shown(5mW and 2W)? Or does the perceived image correlate more to the VLT?


4) Some lasers seem to have a good amount of IR(or other harnful radiation that I don't know), would a safety filter 130 be a better choice than 110(as shown on "laser safety industries")? But the VLT on 130 is only 26% vs 110 at 50%, will I be practically seeing nothing? :cool:
Polycarbonate laser safety glasses are lightweight, economical, and offer excellent protection from lasers. Our laser protection is ANSI and CE (en 205) compliant. Polycarbonate laser glasses and goggles protect from a full range of lasers up to clas

Goggles Filter 110
OD 6+ @ 190-532 nm
OD 6+ @ 10,000-11,000 nm
VLT: 50%

Goggles Filter 130 spec:
OD 7+ @ 190-534 nm
OD 5+ @ 850-1100 nm
OD 7+ @ 1064 nm
VLT: 26%



5) Multiband vs Non-multiband, IR protection
I want IR protection, what wavelength protection should I seek?
I have read that multiband could be jack-of-all-trades but good with a few...probably low OD on many wavelengths. Using the 110 vs 130 comparison above, will I be better off using a IR filter in front of the laser? What brand/model for this filter? Will the point of getting a real multiband goggles be moot?(like ML7 on OEM)
Low OD Diodes/Visible/IR


6) I don't know why, but of a few reputable sites as suggested here on LPF, I rarely seen goggles that cover 600nm(yellow?) laser. Why and where could I find protection for that part of the spectrum?


7) Does different material: Polycarbonate, filter glass or coated glass(as shown on "laser safety industries") has such difference? What will a 2W direct alignment for few seconds call for?



Wow, that's a long long list of questions, but I'd really appreciate all your patience. Any inputs on any part is more than welcome! Thank you!! :bowdown::bowdown:
 





I own the ML7's from OEM Laser Systems, but honestly, you can get a lower range and higher range Eagle Pair from Survival Laser for less money (I have both of those too and use the Eagle Pair more often). You can buy extra pairs of cheaper goggles with the money left over for guests. OEM Laser Systems makes awesome protection equipment if you want to spend the money, but those two pairs of Eagle Pair should do you for a long while and you'll come out around $100 for both. In my humble opinion, you are better off having multiple pairs for specific wavelength ranges rather than trying to pack it all into one pair. Just my two cents...

Good luck! Be safe and have fun!!

KapHn8d,

Those look decent, and I have seen quite a few reviews on them. My main concern is I might not be able to fit my large head with glasses inside these goggle, that'd be a real bummer.:o

But glasses for guests is also a great suggestion, I would look into that as well.
