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". IMPORTANT: Minimum order for this item is 50 pieces at .40 each. To receive the quantity discounts advertised, you must add the quantity you're ordering to the quantity box on the order page. Review: Amazing science for the money - Amazing science for the money Review: 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. ## 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00K6K3MCW | | Best Sellers Rank | #110,910 in Electronics ( See Top 100 in Electronics ) #94 in Lab Microscope Accessories | | Manufacturer | Rainbow Symphony | | Manufacturer reference | 01603-25 | | Product Dimensions | 5.08 x 5.08 x 0.33 cm; 18 g | ## Images ![Rainbow Symphony Diffraction Grating Slides - Linear 1000 Line/Millimeters 25 Pack 01603-25 25 - Image 1](https://m.media-amazon.com/images/I/71YEaN0HL+L.jpg) ![Rainbow Symphony Diffraction Grating Slides - Linear 1000 Line/Millimeters 25 Pack 01603-25 25 - Image 2](https://m.media-amazon.com/images/I/51pqHYobxfL.jpg) ## 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 ### ⭐⭐⭐⭐⭐ Amazing science for the money *by L***D on 7 January 2023* Amazing science for the money ### ⭐⭐⭐⭐⭐ Review *by R***N on 27 September 2025* These diffraction gratings are amazing little things.
