See the spectrum of a light source (Is it halogen, fluorescent, metal halide?) without an expensive meter.
These are great for understanding how lighting works. If you look at an incandescent light bulb through the slide and a little askance, you see a stretched out version of the light that looks like a rainbow.But if you look at a fluorescent source, you instead see multiple copies of the fixture in discrete colors (shades of red, green and blue) that reveal that the light comes from phosphors that emit these colors. Even if these lights claim to be "full spectrum", the actual spectrum is a discrete sampling of frequencies which together let us see as if the full spectrum were present. Various industrial lights, such as metal halide parking lot lights, have unique and identifiable spectrums.If you want to tell one type of light from another, these slide are infinitely more portable and cheaper than $5000 electronic meters! That said, people don't immediately get the knack of looking askance at a light through a slide. A fancy meter will work better for customer presentations.

Fun little things to give out to people.
These diffraction gratings are amazing little things. There are 1000 lines per millimeter, causing light to be separated into the various components, like a prism would do. They're great gifts for curious minds. I give them out to people at the checkstand often, just because.The irony is that if you buy a pack of 20, it only costs around ten bucks, where if you only buy a pack of ten, it costs 12 bucks. Very strange indeed.

Work Perfectly
Work perfectly. Film secure in the slide frame.

not nearly opitical grade
While the items were received in good condition and seem to work as advertised but the film is loose in the holders. This causes the film to not be flat. I think if you cut the film and attached it to a microscope slide it might work for more precision work.

Good
These gratings work well. I received 25 gratings as advertised. and I'm glad I did. I only needed a few gratings for DIY spectrometer I was making. 4 or 5 of these gratings had either some nasty fingerprints or some sort of dust/dirt. The rest of the 20 were acceptable. I saw some other offers for a little less money but only for 10 gratings. The rejection rate is high but if you receive 20 out of 25 usable ones it was just fine with me
