I’m with you on white light lumens. Everyone wants a ton.

Go shoot even 500 lumens at a white wall in the middle of the night. Good luck seeing anything after that.

Also, id check what frequency your specific laser is using, IIRC I've seen some russian lasers listed as 830nm.

Also, speaking of laser eye injuries, IIRC we had a member here a few years ago that manged to blind himeself in one eye, something like he left the laser on, took off his nods and managed to look into the beam. I can't recal if he was permanently blinded or not. So for all the bravado here it can and does happen.

It was just over a year ago. I found the story compelling enough to keep it bookmarked on my browser.

Zenitco posted that they will be available in March, ivantactical will probably have them then or soon after. Zenitco also updated the perst 3 to use the same style switch as the perst 2 so that you can adjust brightness and such, they even have a green laser version and tan version as well.

So these are what I ordered. www.ebay.com/itm/Revision-Sawfly-eyewear-system-4-lense-system-Smoke-clear-green-yellow/173713730565?hash=item2872252c05:g:FPAAAOSwHMJYGT2B

I had seen a couple of other people on hear, that I respect say that they use the Sawfly's with the laser lens.

Per a phone call with Revision they only make 3 laser lenses for the sawfly. I just re thought about putting the specs on them out on the web for everyone... no telling who reads this and our troops use them. And they didn't say they where rated for 850, and didn't give me a graph. Just ratings at 1064nm and one of the lenses is also rated just lower than 800nm with the same rating it has at 10640nm (so going on the hunch, that's it probably about the same at 850, since 850 is between the rating numbers they gave me, but I don't know) And this kit comes with 2 of the 3 lenses they make for them.

I found a spiffy little crude calculator, that was for figuring the min OD rating of glasses to use. It said 850nm at 4mw you need .72 OD min (one of the Sawfly's where rated OD 4 at above and below 850 so thinking even if they are crap at 850 (and I don't think they would be, I would think the US military would be worried about Russian export lasers)) My thought is they should surpass the .72 OD that I should be using with the 2IKS+

If you entered the number for a Pert-3 or 4 aimer of 850nm and 20mw It said you need 1.42 OD

I don't know on the illuminator But if you punch it in like it's a laser it comes back that you should be using a 2.81 OD

But this is all based on trusting the Russian advertising on what they SAY the power and nm is.... They might be stronger than they say, or they might be lower like a 820nm and on mine... 820 vs 850 said I needed a .78 vs .72 so that could change things. And again, these are minimums, and don't discount proper use and safety. Just having been flashed in the past. I wanted safety glasses that had some laser protection when ever I take that Russian unit out and with the reading I have been doing.... You guys running a Perst 3 or 4 or any full power unit. You really should have some kinda laser glasses. You won't know till it's to late.

Thanks for posting the link to that other thread. Good info, and something to think about.

Oh and on the Oakley's. They where a little cheaper, and they look like there better (for this application) tighter to the face, and easier to see though at night, and probably nicer to ware. But I couldn't find any mention of there OD ratings. But I also didn't phone them. So I went with the one that I found OD ratings on. Even thought sigh... they didn't specifically list the frequency, that still bugs me. So I don't know. And Skyhawk... That was your 1,000 post. lol Sorry... Hope you have a great day.

The 3rd lens that Revolution makes for the Sawfly is the E25. I would like to buy one, when I can find it. It is rated for 820-850 and also 1064nm. But I haven't found anyone selling them. So if anyone has seen the chart for the V6-10 or T64 I would love to know how they work at 820-850nm ish. I think the T64 is geared more to the guys using 1064, the V6-10 seems to be more broad spectrum and the one I am planing on using. Or knows where I could buy a E25 lens,for a reasonable price, I would love to hear. Thanks

Oh wow! I didn't even notice. Thanks!

I have the Oakley's, and while I have not aimed a laser at my face, I have tested them with Surefire Vampire and Inforce WML IR LED based lights and they do block them.

I was thinking of making a video review. Maybe I'll do it.
Link Posted: 1/31/2019 9:28:52 AM EST
If we want to test some glasses to see if they block a laser we should be able to just shine the laser through the lenses (while not on our heads) towards a wall, and if we don't see a dot when looking through NV it's GTG, right? Or am I missing something here?

I am super cautious about my PERST-1. I don't ever mess around with anything towards the muzzle end of the gun without first checking the LED indicator to make sure the laser is off. I figure it should be treated the same way as a gun, don't ever assume it's turned off / unloaded. Still, I would like to have some protective lenses to guard against reflections or accidents.
Link Posted: 1/31/2019 12:39:34 PM EST
alemonky. That's what I was thinking. BUT I am going to use my NVG7 to do it (that way I have both eyes covered and protected). Because the whole concern I have is. It hits something close and bounces back and lol testing glasses would be the perfect way to flash your self... Because your close to it, and shooting it at a hard surface. I am going to test the V6-10 and T64 and see what they do with my OTAL and my 2IKS+ since these two lasers aren't listed in the ratings of the glasses. Revolution, is great, they sent me some info on all the lenses they make (the E2-5 is the lens we seek, I think, and I have asked where I might be able to buy one), they make more than 3 lens. I was wrong. But still didn't send any graphs, just the ratings at exact frequencies of different military lasers. Like Harlikwin warned a lot of the stuff is geared toward 1064. I don't know how well these two lens will do on the civilian stuff and Russian stuff.

And Spyhawk. I would love to watch your video. But be super careful.... The reason for these glasses is to protect you if you accidentally hit something up close (plus from the actions of skeeter and weasel). The brightness of that dot or illumnator hitting something up close can cause eye damage. And testing the glasses, is creating the type of event, that we are wanting to a void and protect against. I would hate to see someone get hurt testing glasses....

Me too. Thinking about a PERST unit in lieu of another CQBL-1 for an AKS74UN.

Sorry that I sorta derailed this, I am going to jump over to the safety glasses thread for that part of the topic.

Looking forward to hearing what you guys think of the Perst 4. I just wish it had illumination. That's why I went with the one I went with... I felt I had to have illumination at the same time, and didn't want to pony up for a Perst 3. I am happy with what I got, and inside 200 (where you are going to use a laser, the 2IKS+ is awesome, if they where the same price and I had the choice. I think I would go with the one I went with rather than the Perst 4). So I am wondering why more people seem to be into the Perst 4 vs the 2IKS+ wonder what I am missing... The 4 is lower profile and the 2IKS is sorta a blob that hangs way out (like a flashlight). Is that it? Or is it the visible laser so you don't have to use IR to site it in?

These came in and I had a quick chance to try them out. From a safety standpoint, both of the laser lenses provide complete protection at ~850nm. Multiple order of magnitude reduction. Plastic filters typically don't have very sharp transitions so if something is good at say 850nm, it'll be adequate at 820nm as well. If you or anyone else is extremely curious, I can throw either lens on a spectrometer and determine the attenuation at any arbitrary wavelength.

Thanks TXDX that's awesome. I am glad you shared that.

Last post on the topic of eyes, but I just recorded the video. Will take a couple days to edit then I'll post a link in the glasses thread.

I would really like a Perst-3, but the more I think about it, I think a Perst-4 makes more sense for me. The onboard illuminator would be really nice, but I have no use for a laser pointer that powerful. Last time I was out I was able to bounce my Perst-1's beam off windmills that were a couple miles away, so it's more than powerful enough for any shooting I'll do. The 4 isn't much more powerful than the 1, but the ability to adjust the beam intensity would be nice, and the coaligned green laser would sure make zeroing easier. Might have to pick one up the next time Ebay has a 15% off coupon.....

This is some of the best information I have seen regarding the Zenitco lasers.

As for the price of the Perst-2, Zenitco speculated on facebook it may be around $1400-1500. This was 4 months ago when it was announced so could have changed since then.
Refer to the comments on this post:
https://www.facebook.com/zenitco.ru/posts/2204838393130230?__tn__=-R

While the white light is a somewhat dubious feature I feel like people may be overlooking the other positive features.

One of the biggest benefits for me is that the Perst-2 has your typical threaded cap style battery compartment. The Perst-3 has the battery housed in a compartment accessed by a plate held down by screws. This is obviously undesirable because you need a tool to access the battery and you're in a bind if you misplace the screw(s).

You also have the 18650 battery which should offer longer battery life than the single cr123.

Biggest downsides I see here are the increased weight and that the fire buttons on the unit itself are moved to sub optimal locations.

Hah, I was gonna say you got that thing crazy fast. I think I ordered the PERST-3 same day as you from Russia (2/6) and it looks like it just left customs today as best I can tell. I look forward to your feedback if you do take it, please post. Even when I do get it I have no idea when I'll get to live fire with it.

I’d be interested in the Perst 3 or 2, but not because of the lightsaber laser, rather for the Illum.
