Okay this might be fun. I ordered a focus able 300 mw ir laser module from ebay. Too bad it is 808 nm, but I will also get to see how visible 808 is.

I am going to see how wide of a beam it can make, or I could have an eye ball burning laser pointer.

All for the low price of 20 bucks.

edit,
Holy cow this an honest light saber, when focused to a dot at 200 yards or so just the splash off the tree it was aimed at lights up a 25 yard circle of woods. I ran it out to the widest I could get it. The bar was 20 feet or so wide and 5 feet tall and the area in it was lite up like my amazon special at 10 feet bright. I honestly think it was causing my tubes to gate down some, from over 200 yards away. I am going to order a lens to put on this thing and figure a way to mount it. I think if I get the lens right and get a 20 degree beam it should be good for 200 to 300 yards if not a lot more. I dont think it being 808 nm would matter from a few hundred yards.

BTW I did not mention I also have a 50 mw and a .7 mw 850nm modules coming too. I might order a 100mw after i see what the 50mw can do. There is a chance 300 mw is too much.

another update Okay the .5 mw 850 module came in. Again wow another light saber, just not as dangerous. At 225 yards or so hell of a good dot brightness. When defocused as far as I dare do to the lens being loose it makes a great light too. It give a beautiful circle that has the top and bottom cut off so not perfectly round and it lights up so well I can see just light close range with the amazon special ir light. So even a .5 mw would make a decent light.  

I still have a 50 mw 850 coming in. I will probably order a 940 just to see what its like.

I plan on trying to build a light laser setup kind of like a mawl, with an close iluminator with a wide beam and a longer range one with the 50 mw 850 zoomed in to a 4 or 5 degree beam with a pointer/aiming laser made from the .5 mw I just got. I have come up with a control setup I think will work well. It will be a pressure pad to turn on power which will always do the pointer, then it will slide forward of center for long range, and back for close range. So the pad will have 3 positions, pointer only, pointer and long range, and pointer close range. It will be a real change on the fly system, no need to even adjust grip just push or pull with my thumb and can even be pre set for either range use as it will click in the forward or rear position. Everything is pretty simple and I have the equipment to mill it out. The only real tricky thing is the the adjustment for zeroing, and I think I have figured that out.  My goal will before it to be 12 oclock mounted and no taller than 3/4 on an inch, with the pointer centered over the barrel. The control will be at 10 30 as I hate trying to get my thumb to 12 oclock, I am not a c clamp grip guy.

One way I have thought of doing the zeroing adjustment is like an elcan, only issue is it might need to be taller to do it. Heck the elcan is one of the best scopes out there ( for 1 or 4 power fast change ), might as well copy what works. If it needs to much taller I might just make it at the 130 position

DON'T SHOOT YER EYE OUT

In for optometrist

Well it is sad that used my night vision as safety glasses, with day light covers on, and making sure I could not get a direct bounce back off of the wall.

It works but when unfocused it makes a bar not a square or a dot. I can order a lens to make it open more but I will play at night and see how it works at a few hundred yards if I just unfocus it a little. Might need to order a lens.

Edit might just take a diffuser to make it "usable"

Interesting..............

eta: need link OP

nothing they can do. dead eye is dead.

Pics  / video?

I dont have enough hands, I wanted to but holding the module, my googles and a phone is too much. I made up switch and its a momentary push button for safety reasons and its just too much to do with 2 hands.

10-4. That's definitely something you want to have a good hold of, lol.

how visible is it to naked eye?

Are you offering to stand downrange and let him shine it at you? OP, please don’t.

When diffused isn't it still dangerous to anyone it sweeps?

Well I looked in to it and I cant see anything, anymore, adfadsff akb KSJdaiu aiusgacsc  Cgdq

Just kidding. I did shine it at my drive way and a very quick peak. In total darkness I could see a faint red dot. I cant tell you how big or anything as I was not going to look long enough to measure it.



No, if it is 300 mw at a dot, spread that over an area that is 10 foot circle and its less dangerous that a cat toy. A 10 foot circle is about 11300 sq inches, thats about .026 milliwatts per square inch and how many pupils per sq inch. I still would not tell someone to look at it.

Thanks, was always curious how that affected the "dilution".

pics

optics, agm 50 with omni 7 tubes. samsung phone camera. laser stuck under a patch on my helmet, power button in mouth to turn it on. time taken 930 pm or so zip code 21158, so it you want an idea of time and location.

Kind of hard to aim head, aim goggles, aim camera, squeeze button with teeth, press shutter button on phone. So my aim sucks.

The top of the turn on the road is about 225 yards away, clean view to a tree is about 200 yards. Dot is obviously the dot, two pics one about 200 yards, andone about 75 to show the splash of of the tree. with adjusted to the bar it is covering things from 50 yards to 200 yards. second pic probably about 150 to 175 yards away to the dot

I love it ????

That thing is nuts lol

Yes it is nuts, thru the googles it acts as a flash light when not focused, there is a tree way up there I can see thru the tube. the laser is just blooming.

older pic to show the road when not "lite" except by a amazon special aa ir light

That’s a nice shot of the AGM flaring lol

Don’t burn your tubes with that thing

Believe me I am being careful.

Yes it flared some, but I think I could get Hubble to flare with this.

Okay range tests and other tests.

First I pulled the lens out a led flash light, even with the focus set at a dot, thru a lens its a bar. So the emitter is not square or round, so it it wont work with a proper lens.

But I did a range test at the park near my house. With it focused to a bar, and not getting too weak at 500 yards the beam is about 80 to 90 feet wide and 30 or so feet tall. The longest range I could get was 2066 feet as measured by google earth, the beam was perfectly defined and aimed at trees I could see the trees. Obviously the limit of the non magnified optics in my googles was the limit.

While it is too powerful for what I am playing with it for, not to mention the beam shape. It would work as a long range illumenator, and by long range I mean at least 1000 yards if not 1500 if you did not mind the bar shaped beam and focused it a little tighter.

@lowdown it might be interesting for some of the long range shoots you do.

if you can get one in 940 or higher it would make a good illumination.

I have a 50mw 850nm coming, it will be interesting to see how it does. Might wind up buying a 100mw 850nm at some point just to see how it does.

Well if you really need it....

hmm. tempting. I have a 5v USB battery pack on my helmet. could adapt that to a usb plug... lol.

This guy just recreated the Death Star
