Direct transmission on a Jayrob 270mW is 8.53mW just outside the 5mW Class IIIa range. Whether you use them or not would be your personal call but my recommendation is to have a direct shot to the eyewear attenuate the beam to 5mW or less.

The reason you find red is the lowest OD is because in the scientific community red lasers are the most common color for other laser alignment and targeting. HeNe's and red diodes are often bore sighted to the beam path of higher power lasers. These types of lasers are typically very low power as they are only used for alignment thus only requiring a low OD.

Notice that the range of red attenuation does not include 671nm DPSS and 694nm Ruby. These are always higher power and will never be used for alignment so they are not included.

I just recieved my "Zone-Stealth" gogles for 532nM, they seam really thick and produce reflections on the inside of the lenses, different in each eye, which creates a kind of "ghost-image" that is really distracting. Are the ML7s like this, (relective on the inside)? Also the Zone-steath make everything look really strange and seam pretty dark too. I do not know what the VLT of the ZS's are, maybe you do? The ML7's are like 12% right? I know I am comparing single-wavelength glasses to you multi-wavlength, but these are my only referancere. I am thinking the ML7s are much better qaulity and may have an eqaul VLT even though they are broadband. Do not get me wrong, the ZS are fine for the $, but I want something a little better and more versatile. ;)
I am trying to talk myself into buying the ML7s, I just don't want to buy something that proves to not be very pratical, (remember the calculator wrist-watches?). How about general color rendidition, do they make you think you followed a rabbit down a hole, or just a grey-scale?
Any further info would be great, I love the idea of a single pair of googles for all of my lasers up to 300mW, like I am sure everyone else would. Beside the added cost and lower VLT, is there any other downside to using the ML7's? They seem almost too good to be true.

Hands down i'd vote for the S3 military surplus SPECS glasses, They are light, cheap, and cut out everything longer than about 640 and shorter than 543nm.

On a spectral plot they were od of 3-4 through most of the near IR od of 5+ at 1064, and 694 and od of 3+ with a very sharp cut off at about 640nm. Going the other way there is a sharp cut off at about 543nm on up with an OD of about 3, a small keyhole notch to od 2 at about 445nm and continued attenuation shorter than this. Peak transmission was at about 580 to 570nm

The S3 specs are the olive green ones.

The green SPECS are good for co2 10.6u, YAG 1064, and ruby 694nm as well as anything below 400nm

For those who don't know each OD reduces the power by a factor of 10...

The s1 (solar) GRAY glasses suck flat OD 1 at best for visible wavelengths, almost transparent at most near IR- do not use at all except with co2 lasers, od of 7.

I second this. I REALLY need some safety gear. I have a laser dipping into the class IV range and no laser goggles... I'm afraid to even turn the thing on :o

The ML7s and in fact all our glasses are based on absorptive dyes infused in polycarbonate. They do not reflect laser light endangering someone else. The lenses actually absorb the light. The polycarbonate is tinted based on the dye but crystal clear. The low VLT is indicative of the multiple wavelengths attenuated but is not a hindrance when used properly (as in a well light room). The best part is the lenses are certified. The OD advertised is the OD you get.

Beginning in August we will have every available lens type listed in 9 different frame styles. That translates to well over 500 different lens/frame combinations. Of course most of those will not apply but there will still be plenty of visible light combinations.
 
Thanks FC, this is some good info, can I get a copy of the chart for the ODs? I have almost talked myself into buying the ML7's, I would just really like to hear some reviews and/or any more info. I will probably need a couple pair, (for a friend), so I need to make sure they are worth it.
I know there are members who have purchased the ML7s, anyone care to review your "super-googs"?
I noticed that this thread is getting read a lot, I guess this is quite a popular question. ;)

The spectral response chart for the ML7s will be on the site in a couple of days.

There are a couple of reviews on the site but here's the first one I found:
http://www.laserpointerforums.com/forums/YaBB.pl?num=1209626843

Here's a bit-o-something beginning in August for anyone wanting to group up and buy glasses in bulk. You can get additional discounts beyond the 7.5% discount code by buying in quantity. So if someone wants to do a GB on these you can end up with up to a 17.5% discount. That would put these glasses about the $133.00 mark. The order has to be the same UPC but they can be different frame styles. Actually discounts are applied within a category, so any UPC in a category adds into the total number of glasses for a discount. Unfortunately the base category for the ML7s are: Low OD Diodes/Visible/IR not Visible Alignment. They are just cross-referenced into that category.

This can be done for any of the models. Discounts are applied for 5, 10, 20, 100 items. These will be shipped in quantity to whoever orders them. The purchaser will have to distribute the individual glasses.

Hmm... ::) Interesting, So would there be additional percentages for, say 5 googles versus 20, or once we get 5 together we could receive the maximum discount? I would think we could get 5-people together pretty quickly, and have this done in a short-time.

[highlight]Is there any interest in a "ML7-GB"? [/highlight]I suppose I could host it, unless someone else wanted to, ( I would just say that I would like to see it happen quickly, I dis-like long-winded GBs). ;)

The discount percentage is based on quantity. So 5 would give you an additional discount. Ten would be a higher discount, etc. Of course don't forget to include the discount code for a 7.5% right off the top.
 
Just my luck, I order a pair of AL2 and just days later, you post that group buys are becoming available for further discounts. At least I did remember to use that code for 7.5% off, and I'm sure I'll be very happy with what I ordered anyway.
 
Well don't feel bad. From what I've seen about GBs here they take quite a while to get organized so at least you have your glasses now and for the price the discount is no where near what they are for $150.00+ I just wanted everyone to know there are additional discounts if several people want the same glasses.

i would get for $100

I will be doing a group buy for these, but they will not be <$100, I wish we could, I would buy 2 pair.
Hope fully we can get the price low enough that several people will end up with proper-protection and not be the subject of some head-line about the dangers of laser-use. I think many people are trying to get by without the proper protection, hopefully this will provide an attractive solution for some fo us that would otherwise need 4+pair of googles. ;)
Keep an eye on the GB-thread!
