Question what makes a milspec Laser?

I've got one laser designed for mounting on a rifle or "BFG" pistol, and when I think about setting up a different colored laser - like violet or whatever, the first concern that occurs to me is the shock destroying it.

I'm worried the soldering mounts will snap, the driver will crack, the lens will shatter, the threads on the focusing ring will shred, etc. Basically, I'm concerned the laser will fly to pieces or break in about as many ways as it has parts - and I'm not even including the possibility that the thing could get wet.

I was wondering if there are some good measures, better parts, or techniques used in assembly and or mounting that can prevent this?

For example, I've got some spongy black 1/16" stuff I originally bought to do some repairs on our truck, and thought if you wrapped the laser in that, and then wrapped the the mounting ring around the foam and tightened it, it might reduce the shock somewhat, but I have no idea.

Some weapons have crazy recoil though, and my understanding is when you attach something to a firing weapon, it's mass changes and the recoil also changes, so the math isn't proportional. Like if you stick a tiny laser on a big heavy rifle, the recoil difference is negligible, but if you stick something like that 2W Frankenstein laser on a .357 (which would be ridiculous), the recoil would be considerably changed.

Then I have to ask if any of this really matters if you have your driver other parts set up properly?

As to answering your title....

A milspec Laser would need to be up to Military Specifications
per any specific Laser.

You would need to hunt down those specifications pertaining
to the Laser in question for the Country you are interested
in.

Default Re: what makes a milspec Laser?

So a milspec laser is a laser up to military specifications? Thank god we have you here Jerry, otherwise these questions may go unanswered

Most simple diode lasers will work for a gun sight. The major components of a 5mW gun sight laser don't have too much mass so even if the recoil was pretty strong it still wouldn't effect the parts all that much. Somewhat like throwing a cockroach off a building, it just doesn't have enough mass to hurt itself. Plus recoil should be a pretty uniform shock across the entire laser, so stress to individual parts should not really happen unless you mount something super loose.

Now DPSS lasers are different, they are more sensitive to vibration than a solid state diode laser. The module would need to be built to really high tolerances to last long on a gun rail.

A laser is going to be pretty light, shouldn't effect the recoil too much. You'll probably want to solid mount it though, no foam, otherwise it will fall out of alignment too easily.

I would have thought that you would have known this....

Glad I could bring YOU up to speed....

thank you!

That answered a lot of my concerns, and I totally get the bug analogy.

www.ngbpdc.ngb.army.mil/pubs/385/ngr385-63.pdf
mentions class 2, 3, 3b, 4, and something called "military exempt lasers"

>

appears to include experimental lasers.

MIL-STD-1425A Military Specifications For Lasers
This appears to be the "go to" document.

Default Re: what makes a milspec Laser?

The common milspec ratings apply to construction and operational requirements. For example MIL STD 810 defines procedures for testing military equipment in the expected environment the equipment will operate within. Anyone building any equipment for the military will become intimately familiar with MIL STD 810. For example, a laser sight may be required to be water resistant to 10 meters, or be able to withstand a specific level of vibration. You would read and follow the procedures for testing immersion and vibration based on the proper annex of 810. My company is actually building a specific design for the military and it must meet several of the 810 specifications. Here's the link to MIL STD 810: MIL-STD-810 F

The latest is MIL-STD-810G

For lasers look at MIL-STD-1425A
