Our Holographic Diffraction Gratings are highly efficient embossed Holographic Optical Elements (H.O.E.). Diffraction Gratings are used for the direct viewing and analysis of spectra from different gas tubes and other light sources. The quality of the spectrum produced from our gratings is the brightest possible with a minimum of distracting visual noise. Our gratings are the principal component in a spectroscope and are used for experiments pertaining to the study of light and color. Project a spectrum using an overhead projector or 35mm slide projector for spectrum demonstration purposes. Use in conjunction with colored film gels for additive and subtractive color demonstrations. ## Features - Makes the study of light and color fun and unforgettable - Features highly efficient embossed Holographic Optical Elements - Used for the direct viewing and analysis of spectra from different gas tubes and other light sources - Spectrum produced from our gratings is the brightest possible with a minimum of distracting visual noise - Great for overhead projector or 35mm slide projectors ## Images ![Rainbow Symphony Diffraction Gratings Slides - Linear 1000 Line/millimeters, Package of 10 - Image 1](https://images-na.ssl-images-amazon.com/images/I/51mPcQXL9IL.jpg) ![Rainbow Symphony Diffraction Gratings Slides - Linear 1000 Line/millimeters, Package of 10 - Image 2](https://images-na.ssl-images-amazon.com/images/I/41FdcHx4piL.jpg) ![Rainbow Symphony Diffraction Gratings Slides - Linear 1000 Line/millimeters, Package of 10 - Image 3](https://images-na.ssl-images-amazon.com/images/I/41t-zVUlXeL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well if you keep it close to your eye and only handle it by the frame. *by T***L on March 17, 2017* There's a potential for confusion regarding how this product works. This is a "single axis" diffraction grating which means you'll see the point source of light ... and you'll see the rainbow "smear" of the color spectrum produced by that light which will appear both left and right of the point source. Hence the name "linear" diffraction grating because it's all in a nice line. However, you WILL need to hold this VERY close to your eye (perhaps an inch or so away) and will still likely need to look out to one side to see the spectrum. That's just the physics of how the prisms are working - not a product defect.One other caution... avoid touching the film with your fingers (or anything else that might leave any oily residue behind). The gratings are basically a 1000 tiny prisms in every inch. If you touch the film, your fingerprint oils will fill in the gaps between each micro-prism and that will prevent the light from being diffracted correctly.I use these to do explain spectroscopy when doing science outreach. In my case I start with an ordinary tungsten filament light bulb, but then switch to using gas tubes with various gas elements (hydrogen, helium, etc.) ### ⭐⭐⭐⭐⭐ See the spectrum of a light source (Is it halogen, fluorescent, metal halide?) without an expensive meter. *by D***S on October 2, 2015* 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. ### ⭐⭐⭐⭐ Good *by G***R on May 8, 2017* 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 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/89900440-rainbow-symphony-diffraction-gratings-slides-linear-1000-line-millimeters-package](https://www.desertcart.in/products/89900440-rainbow-symphony-diffraction-gratings-slides-linear-1000-line-millimeters-package) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-03*
