## Description

Diffraction Gratings sheet are used for direct viewing and analysis of spectra from different light sources. These gratings are the principal component in a spectroscope and are used for experiments pertaining to the study of light and color each sheet is separated by a faint line. The line does not distort or disturb the light quality of the diffraction A4 size 11*8 inch Thickness is 0.38mm Diffraction Gratings Films have spiral effect under lighting this is raw materials for make spiral diffraction glasses ,can not for wall or windows

Review: OK - The quality of the film is not the best. But it gives a nice effect. But the film looks a bit odd and is quite thick. It works as a simple diffraction grating but I was looking for thinner finer grating. Nothing wrong with the product as such, just not quite what I was looking for.
Review: i was expecting a little more rainbow on the wall with this - it probably me rather than product i was loocking for something to project rainbow onto the wall :) also it can easly come apart.

### ⭐⭐⭐⭐⭐ Looks great!
*by J***R on 11 January 2021*

I bought these diffraction sheets after watching a making holographic chocolate video and deciding I wanted to try it for myself. There's two in the pack, which is great and they came earlier than the delivery estimate earliest day of January 19th, so definite plus points to the seller for this! I haven't had a go at the chocolate yet as I haven't bought it in, but as soon as I do I'll put some pictures up of how successful (or not!) my attempt was. The diffraction sheets are very well protected with a sticky sheet on either side to safeguard against scratches. In the envelope itself the sheets were encased in lots of bubble-wrap inside a box and that was enveloped in more bubble-wrap. There was lots of sticky tape on the outer envelope, so I had to use scissors to help me get into it, but that's OK, because it means the manufacturer wanted to protect it well, knowing what postal systems can be like. Holding the sheets themselves up to the light shows a very well-defined spiral rainbow, a little like a fractal. It was this that attracted me to them in the first place. I'm very happy with how they look. Fingers crossed the chocolate gets this pattern too, when I get round to doing it - I'll addphotos at that point!
