thanks i've contacted that seller. I've spoken to a few people about custom diffraction gratings and the lowest i've been charged is $20,000 so that's not gonna happen :crackup:
I should have clarified in my original post, the shape is actually a pentagram. so a 5 sided star with a circle...
Hi there i'm new :beer:
i was curious if it'd possible to make custom shapes in those lenses that screw on the caps of laser pointers? After some research I don't think a grating is what I need since it diffracts lights in all directions.
I remember as a kid they had these tips with a pointer...
