Made in the USA, these slides are compatible with projectors and ideal for classrooms, homeschoolers, and science enthusiasts seeking hands-on light diffraction exploration. ## Description Diffraction Grating Slides-Linear 1000 Line/mm. 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. Review: 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. Review: Work Perfectly - Work perfectly. Film secure in the slide frame. ## Features - DIFFRACTION GRATING: Rainbow Symphony's Linear Diffraction Grating Slides (1000 line/millimeter) allow you to directly view and analyze spectra from multiple light sources, including gas tubes, making the study of light and color fun and educational. - QUALITY MATERIALS: Our 2"X 2" diffraction grating sheet slides were designed with quality material to produce the brightest possible spectrum with a minimal distracting visual noise, while being long lasting.

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 *by A***M on March 29, 2026* Work perfectly. Film secure in the slide frame. ### ⭐⭐⭐⭐⭐ Excellent Product *by K***E on August 28, 2024* I got the 500 lines/mm and it works amazing. Using an extremely narrow slit, I was able to see Frauhofer lines in sunlight (never look directly at the sun) I calculated that there are actually about 521.7 lines/mm. Make sure to check the value against a source with a known wavelength if you want to do quantitative applications. ## Frequently Bought Together - Rainbow Symphony Diffraction Grating Slides, Linear, 1000 Line/Millimeters, Made in USA, Package of 10 - 3pc Equilateral CrystalPrisms Set -1",2" & 4" Lengths Crystal Triangular Prism Optical Prisms Glass Physics Teaching Refracted Light Spectrum Rainbow Maker Photography Props --- ## 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.ae/products/18763775-rainbow-symphony-diffraction-grating-slides-linear-1000-line-millimeters-made](https://www.desertcart.ae/products/18763775-rainbow-symphony-diffraction-grating-slides-linear-1000-line-millimeters-made) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-05-10*
