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. 2" X 2". 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 (500 line/millimeter) allow you to directly view and analyze spectra from multiple light sources, include 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. It features efficient embossed holographic elements. - EDUCATION: Our diffraction grating sheet slides are perfect for classroom or homeschool physics education on visual displays of light diffraction. Each slide has a scale to help you measure wavelength in nanometers, making observations simple to record. - PROJECTOR COMPATIBLE: These slides can be used to project a spectrum using overhead projectors or a 35mm slide projector for spectrum demonstration purposes. Use in conjunction with colored film gels for additive and subtractive color demonstrations. - MADE IN THE US: All of Rainbow Symphony's diffraction grating film slides are made in the US to ensure the quality. These rainbow maker slides are perfect for kids, physics lessons, educational toys, classroom supplies or homeschool supplies. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.4 out of 5 stars 347 Reviews | ## Images ![Diffraction Grating Slides, Linear, 500 Line/Millimeters, Made in USA, Package of 50 - Image 1](https://m.media-amazon.com/images/I/51PewL5YFAL.jpg) ![Diffraction Grating Slides, Linear, 500 Line/Millimeters, Made in USA, Package of 50 - Image 2](https://m.media-amazon.com/images/I/21x8y9f-mLL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fun little things to give out to people. *by R***N on September 27, 2025* 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 *by A***M on March 29, 2026* Work perfectly. Film secure in the slide frame. ### ⭐⭐⭐⭐ Basic, but good *by A***R on February 12, 2025* I used these with my chemistry students to create their own spectrometers when reviewing the electromagnetic spectrum. They worked well for differentiating between continuous and discreet light spectrums. They’re nothing fancy and you can’t get too specific of a read on them, but they work well for a basic lesson. --- ## 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.tn/products/125761673-diffraction-grating-slides-linear-500-line-millimeters-made-in-usa](https://www.desertcart.tn/products/125761673-diffraction-grating-slides-linear-500-line-millimeters-made-in-usa) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-01*
