I bought a cheap violet laser, this is the link Amazon.com: 10mW Blue Violet Laser Presentation Pointe: Electronics, and from all the things i have read in the forum and the pictures i see i think its over spec, but the problem is the divergence of the ray, is there a cheap and easy way to improve the divergence, like a cap with a lens or something like that.

Thanks

This wavelength will play tricks on your eyes. Have you set the laser so it stays on
pointing at a wall and actually walked up to the dot to check its divergence? 405nm
light will produce a laser dot that starts to look blurry even from just several feet away,
the only way to truely see the size of the actual dot is to get up close to it while its on.

In the event it truely does have bad divergence, the only way to correct it would be to
adjust to collimating lens, which may require some disassembly. My advice, don't bother
with it.

Thanks Gryphon, yes i have measured the dot of the laser, and i compared it to my aries and its like 3 times bigger at the same distance, i was to lazy to grab a ruler.
