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: n(lambda)=2dsin(theta) - Used this grating with a red laser pointer to demonstrate diffraction to a bunch of lucky chemistry students. I really hope they learn Bragg's law after I went to so much trouble. Review: Good buy - If you are after fun with solar spectrum then this is for you it is on a 35 mm slide and that helps ## 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 - Great for overhead projector or 35mm slide projectors ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00PBDTJ0I | | Batteries Required? | No | | Batteries included? | No | | Colour | 13,500 | | Customer Reviews | 4.2 4.2 out of 5 stars (305) | | Date First Available | 15 Feb. 2013 | | Item Package Quantity | 1 | | Item Weight | 9 g | | Item model number | 01602-10 | | Manufacturer | Rainbow Symphony | | Material | plastic | | Number of Pieces | 10 | | Package Dimensions | 8.99 x 6.1 x 1.09 cm; 9 g | | Part number | 01602-10 | | Size | 10-Pack | ## Images ![Pack of 10 Diffraction Grating Slides - Double Axis 13,500 Lines/inch - Image 1](https://m.media-amazon.com/images/I/51v8D2NAgyL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Will it chop frozen grapes?** A: I just tried. This is ineffective against frozen grapes. **Q: What is the difference between the various options?** A: Basically the line spacing. We offer 500 ln/mm, 1000 ln/mm and cross axis 13,500 line/ in. The 1000 ln/mm spreads the spectrum the most. **Q: Your scale is backwards. Red is the longer wavelength.** A: I think they meant the scale to be applied to the rainbow colors of the plastic part itself (just as a side reference relating color and wavelength), since the positions of colors on the grating depends on angles etc., they aren't tied to a specific position on the grating anyway. **Q: Could anybody provide me more technical information or a datasheet? For example, the manufacturing method or the grooves' angle. Thank you in advance** A: Sorry, just the line spacing. ## Customer Reviews ### ⭐⭐⭐⭐⭐ n(lambda)=2dsin(theta) *by L***S on 16 April 2021* Used this grating with a red laser pointer to demonstrate diffraction to a bunch of lucky chemistry students. I really hope they learn Bragg's law after I went to so much trouble. ### ⭐⭐⭐⭐⭐ Good buy *by T***C on 17 November 2020* If you are after fun with solar spectrum then this is for you it is on a 35 mm slide and that helps ### ⭐⭐⭐⭐ The ordered Diffraction Grating Slides work well *by A***R on 30 January 2019* For a course on optics I ordered a Pack of 10 Diffraction Grating Slides - Linear 500 Lines/mm. The slides were packed and delivered well and work well. ## Frequently Bought Together - Rainbow Symphony Diffraction Grating Slides - Double Axis 13,500 Line/inch, Package of 10 - EISCO Premium Quantitative Spectroscope - 400-700nm Range, 5nm Accuracy - Diffraction Grating Slide-Linear 1000 Lines/mm 2x2"-Pack of 10 --- ## 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.sn/products/420380133-pack-of-10-diffraction-grating-slides-double-axis-13-500](https://www.desertcart.sn/products/420380133-pack-of-10-diffraction-grating-slides-double-axis-13-500) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-25*
