Its double axis design and manual focus, combined with tripod compatibility, make it an essential tool for educators, scientists, and hobbyists seeking precise light spectrum analysis across all ages. ## Description These are Holographic Diffraction Gratings, 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 these gratings is the brightest possible with a minimum of distracting visual noise. These 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" ## Features - Roll of 5 diffraction grating sheets 13500 lines/mm - Size: 6"x60" / 15x150 cm - Highly efficient, double Axis, embossed Holographic Optical Elements (H.O.E.). - Use for the direct viewing and analysis of spectra from different gas tubes and other light sources. - Spectrum quality - the brightest possible with a minimum of distracting visual noise ## Technical Specifications | Specification | Value | |---------------|-------| | Product Dimensions | 15.2 x 15.2 x 15 cm; 18 g | | Manufacturer recommended age | 3 years and up | | Item model number | 01506-5FT | | Assembly Required | No | | Batteries Required? | No | | Batteries included? | No | | Remote Control Included? | No | | ASIN | B007FZXNL6 | ## Product Details - **Brand:** Rainbow Symphony - **Model name:** RM - **Optical tube length:** 150 Centimetres - **Eye piece lens description:** spectral analysis eyepiece - **Objective lens diameter:** 6 inches - **Telescope mount description:** Tripod Mount - **Product dimensions:** 15.2D x 15.2W x 15H centimetres - **Focus type:** Manual Focus - **Power source:** Manual Operation - **Finderscope:** Reflex ## Images ![Rainbow Symphony Spectroscope - Double Axis 13,500 Lines/mm, 6"x60" / 15x150 cm, Manual Focus, 2" Eyepiece, Tripod Mount, Unisex, All Ages, Educators, Scientists, Hobbyists, Students - Image 1](https://m.media-amazon.com/images/I/31Y1QdWBFcL.jpg) ## Questions & Answers **Q: Can you please tell me *precisely* what type of plastic these defraction gratings are made of? Not all plastics can be laser cut.** A: the film is a polyester substrate with an embossed holographic pattern. the diffraction pattern is not actually cut...it is embossed! **Q: how do you apply this to a window? I have a window on the top 1/2 of the main door to my house. If I apply in strips, will the lines look bad?** A: Diffraction grating works by having 100's of tiny lines that basically diffract the light into rainbows. These lines are physically etched into the thin plastic. Even finger print smudges effect this. You couldn't glue it on bc the glue would fill in the lines. I'd recommend those sticky "glue dots" in the corners. I don't know if the strips will look bad because I can't see where you are putting it but I doubt it would be that much of an issue. I'd think that something like this would have to be redone every few years b/c it can't really be cleaned. You'd also want to make sure that it wasn't touched often or... you could set everything up and screw a piece of plexi over top that's cleanable and wouldn't have to be worried about how delicate it is. That would protect the diffraction film. Also, as a side note, there has to be direct light in order for this to cast rainbows. **Q: I want to put this on the outside or inside of a glass elevator. What should I use to attach it to the Glass so that the other side also looks good.** A: There is a video where EvanandKatelyn use UV boat resin to mount it to wood. It looked fairly good. If you can remove the glass to attach it, it might work. **Q: I want to make my own fireworks glasses. Is this what I would want as the lenses (the double axis)?** A: Yes, I would recommend you that. Sheet 13500 lines/inch reflects in 8 directions, so it's really good for firework glasses. ## Frequently Bought Together - Diffraction Grating sheet 13,500 lines/inch - Double Axis 5ft Long x 6 inches Wide - Diffraction Grating sheet 1,000 lines/mm Linear 5 Foot x 6 Inches Wide - 13,500 Lines/inch Diffraction Grating Sheet - Double Axis [5 Feet x 6 Inch Roll] --- ## 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.vu/products/50078575-rainbow-symphony-spectroscope-double-axis-13-500-lines-mm-6x60](https://www.desertcart.vu/products/50078575-rainbow-symphony-spectroscope-double-axis-13-500-lines-mm-6x60) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-02*
