Misaligned Laser Pen

[givemesome]

Hi all. I've recently purchased a laser from http://www.telescopehouse.com/cgi-b...nter_5mw___Case__226.html#a4_21SP32#a4_21SP32 (sorry don't know how to shorten link) and I am using it as a gun sight. I noticed the beam does not project directly infront of the pen, it peers over to the right at a slight angle. Does anyone else have this problem? Is there anyway I can fix this? I've tried to undo the cap on the end but i think it's superglued on lol and it defeats the purpose of the laser really if I can't use it to aim accurately...

First time I hear about that but anyways, I think that must be the lens, the last one must be a bit moved, trying to open it. Anyways, 5mW for that price= scam. Go dealextreme and buy a new one, they are all good aligned

A slight misalignment is common.
If it is really really bad then I would send it back, otherwise, I would just get a better laser.

Unfortunately, fixing it could be difficult.
The problem could be one of the lenses, the crystals, the diode, or any other component that is a fraction of a mm off-center.
It can be fixed, but you would probably be best saving yourself the trouble and getting a real laser sight with adjustable output alignment.

LOL!!! $12 WAH AHAHAHAHAHHAHAH BWAA HAHAHAHHAHAHAH..... gutted... Alignment aint too bad, it's just one tiny tiny tiny fraction of misalignment which makes it totally useless for aiming

I have yet to find a green laser where the beam comes out straight, if you think about the beam path through crystals, filters and lenses it is hardly surprising.

You need to modify the mount so that it can be adjusted at both ends. It doesn't matter if the "housing" of the laser is aligned with the weapon. It only matters that the beam is aligned with the weapon.

I have a vested interest in this very problem. Not weapons but green laser alignment. I have an expensive laser and the beam does not come straight out. This would usually not be a problem but I am using a beam expander and besides cutting off about 20% of the beam makes a radial "flare" to one side. How much trouble is it to make a beam that comes out, hope I get this right, concentric to the long axis of the laser body/ housing? I would not do this myself. More of an academic question. Daguin? Your an academic

If you want a green laser gun sight, but a green laser gun sight. It will have three features a laser pointer doesn't:

1: The ability to adjust the beam alignment to match the bullet impact point. This is required for all gun sights, as simply changing brands of ammunition will change the impact point of the bullet. With handguns, changing the way you grip the weapon can affect where the bullet strikes as well. A looser grip increases the amount the muzzle rises due to recoil before the bullet leaves the barrel, raising the impact point. Any sight that cannot be adjusted is useless except at very short ranges.

2: The ability to withstand the shock of repeated firing without falling apart. Green lasers (especially cheap pointers) are delicate beasts, and simply dropping them can knock them out of alignment. I have a pointer that fell apart completely inside after dropping it on the floor. Gun sight green lasers have extra-rugged mounts for the crystals and optics to keep them working shot after shot.

3: Weather-sealing, so that exposing them to rain or water splashes won't short out the electronics or mess up the optics.

An actual green laser sight is more expensive than a pointer, but these are the reasons why it is worth the extra cost to buy the correct tool for the job.
