FS: Linear Diffraction Gratings *SOLD OUT*

[lamborgini8]

*SOLD OUT!*

I am selling a few linear diffraction gratings that I have had lying around for some time.

I have 20 small 2x2cm squares and one larger 10x8cm sheet with blue protective covers over. I will be honest and say that they haven't been cut very well but the worst is 1mm out so its not so bad. The 2x2 squares do have fingerprints on some of them which are pretty hard to clean but they do come off if you use a soft cloth although it doesn't make much difference to the effect given.

One square will give a linear effect and two squares can be doubled up to give a matrix effect.

I will sell each square for £1.50 each, shipped. More can be cut from the larger 10x8cm square more accurately if you wish.

Scroll down for dot and beam pics.

All depends on if the room is smoky or not.

The pictures above are from a green 50mW module in a smoky room, I even made another picture in the multimedia forum of the same greed module and a 80mW red yet the beam on both are visible.

Re: FS: Linear Diffraction Gratings *2 LEFT*

I have two more up for sale, same price £1.50 shipped.

Again these are inaccurately cut 2x2cm squares, and give a fan effect although two doubled up gives a matrix effect.

Please note these are plastic, not glass.
