my custom greenlaser diffraction grating addon

Hi guys, what i have here is my custom add on diffraction grating on my 150mw green laser (o-like module) on rayfoss host.

here is the picture..



the Diffraction grating in Action!





Note: the only con on my addon is that you have to remove the head of the rayfoss host to have it added on the barrel of the module.

but im enjoying these one. if you will rotate the addon.. it will give you a twinkle star effect.


im planning to make again.. but my machine went down due to over use... hehehe i will have to wait until 2 weeks for the complete repair...
