Description of π Rainbow Symphony 10-Pack Linear 500 Line/mm Diffraction Gratings Slides: Explore Spectral Magic!
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.
They were of excellent quality. We used it for my 12 year high school science fair project, she used it to build a photospectrometer. A small prize for a great science fair project.
Pros
Used for direct viewing and analysis of spectra from various gas tubes and other light sources
I wanted something cheap but powerful to get my point across in high school physics class. It is in order. You will not measure wavelengths on a diffraction pattern with a small scale below. As you move your eye, the diffraction pattern shifts, so the scale is just for looks.
Pros
Includes high performance embossed holographic optics
I bought these for my class as I'm a science teacher. They were a great bargain for the price as I always keep track of my purchases! They work very well and clearly show the difference between the gradients. I have used them several times and I use them very often.
Pros
Makes learning about light and color fun and memorable
