Hi, Anyone know where to get ??. I want to get some kind of lens or filter that goes in front of a laser modual that will produce dots in a Vertical line. Have used in the past with light organ output triger (low freq range output) on the ttl input to laser gun. A cheap laser sky effect. Any Help? Thanks

E-bay is a good source for plastic film diffraction gratings. Here's a link:

Just cut the plastic out of the paper frame.
