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 - 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. 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 USA: 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 gifts, physics gifts, educational toys, classroom supplies or homeschool supplies. ## Images ![Diffraction Grating Slides, Linear, 1000 Line/Millimeters, Made in USA, Package of 10 - Image 1](https://m.media-amazon.com/images/I/71ihuCJbOqL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ These diffraction gratings can easily be used to make spectrometers for STEM projects. *by M***K on March 15, 2025* These pre-mounted diffraction gratings are what you need if you want to make a good quality home made spectrometer. Sources for getting these gratings have dried up and this vendor is one of the few that still supplies them. The make a great STEM project for beginning science students. Another use for these gratings is to measure the optical frequencys of inexpensive lasers for Bath interferrometers ### ⭐⭐⭐⭐⭐ 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. ### ⭐⭐⭐⭐ 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. ## 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.hu/products/18763775-diffraction-grating-slides-linear-1000-line-millimeters-made-in-usa](https://www.desertcart.hu/products/18763775-diffraction-grating-slides-linear-1000-line-millimeters-made-in-usa) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-04-26*
