It's plastic. It feels like a toy. But it's vastly better than all the other under $100 spectrometers on the market.The original 1991 version had an adjustable scale so you could calibrate out any scale error. This one still mentions that on a sticker, but the scale is NOT adjustable.Mine reads low by about 1.5 nanometers. You have to squint to use it; it's awkward.But if you're careful you can read lines to the nearest 1 or 2 nanometers.The EICO and all the other ones I've seen (I think I bought all of them) are worse. This one is not great, but it's by far the best for less than $100. Nothing else is even close.Update 2024-11: Google on the "little garden spectrometer". It's a electronic gadget, doesn't cost much more than this, and is vastly more capable. With that one you read the spectrum on a computer screen. ### ⭐⭐⭐ This actually works *by P***S on August 13, 2023* The instructions are very poor and if you do not have prior knowledge of how to use it you may struggle to figure it out. Point the instrument at a light source and rotate the grating until the refracted light illuminates the scale in the instrument. ### ⭐ Awkward to use. Never able to demonstrate satisfactory performance. *by C***. on March 9, 2020* I intended to use this spectrometer to have my grandson learn about the spectrum of light.To use it you aimed the slit side at the light source and then looked away to the left to see the spectrum. This was awkward with the hand held spectrometer as I would lose the aim to the light source. It seemed impossible to ever keep a small light source aligned. I would not want my grandson to try to use it and get fustrated.There was no focusing that I found so I had to look through the close up part of my tri-focals to try and focus on the spectrum. The lines did not look too sharp. ??Hard to use and I quit after 30 minutes of trying to optimize its use. Minimal instructions for using the spectrometer. ## Frequently Bought Together - Arbor Scientific Project Star Precision Spectrometer, Spectra Observation Instrument with Built in Chart, 31 x 18 cm - EISCO - Economy Spectroscope Tube Pack of 6 for Classroom Optics Light Spectrum Analysis and Diffraction Studies - EISCO Premium Quantitative Spectroscope - 400-700nm Range, 5nm Accuracy - for Studying Light Sources, Measuring Wavelengths & Color Spectra --- ## 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.com.cy/products/125218820-project-star-precision-spectrometer-spectra-observation-instrument-with-built-in](https://www.desertcart.com.cy/products/125218820-project-star-precision-spectrometer-spectra-observation-instrument-with-built-in) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-23*
