Review on π Rainbow Symphony 10-Pack Linear 500 Line/mm Diffraction Gratings Slides: Explore Spectral Magic! by Nick Narvasa
Get what you pay for
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
Cons
- I don't remember
