Not what I expected, but fun, useful, and fair quality. Prisms refract the light into a room environment, these diffract that light coming in, so that they need to be near (your eye or a camera lens) to see the diffraction effect. Recommend using for camera filter effect vs. not held to your eyes, because the spectral output is different pure frequencies that could damage your eyes (probably not, by why chance it?). Fun and great quality for a slide style, but there is some dust as another reviewer mentioned. Dust is Not hard to removed with a camera lens brush.

I teach science and this is a great way to introduce diffraction and the double-slit and multi-slit experiments. If you also get flashlights that can project both laser and white light, you can show the multi-slit effect with the laser as well as a beautiful rainbow that will attract the attention of younger learners. If you get different color lasers, you can demonstrate that the diffraction angle depends on wavelength, which will in turn explain the rainbow. Provides great teaching material.

I've used these for a variety of things, they are fun to play with and surprisingly accurate when messing around measuring the wavelength of lasers and stuff, you can easily make a rudimentary spectrophotometer or monochromator with one. Can't beat the value

I compared the 1000 lines with 500 lines, and have to say that the 1000 lines is definitely able to show more details in spectra. These are great for introductory spectroscopy discussions in Astronomy classes; what I use them for. What a student can expect to see after some explanation of what to look for, is a series of spectral rainbows with absorption or emission lines. The lines do change positions based upon elements and energy levels. Yes, that sounds very elementary. But, for a student with no experience, this can be eye-opening and exciting. I found these gratings to be a great introduction to spectroscopy; and, a good lead into using higher-end spectroscopes.

Perfectly serviceable diffraction gratings. There is a little bit of ripple in the surface, so the spectra from them are not perfectly crisp, but they do what they are supposed to do (I'm using them for home-built spectrometers).

I use these when I teach students about light and the color spectrum. They work by holding them up to your eye and peering at a light source. The color spectrum appears as two vertical lines, one extending to the left and one extending to the right. The larger the light source the thicker the lines are. I like to have students look at different colored light bulbs and see what colors are present compared to white light. They are made of thick cardboard, so they should last a while.

Some of them had distortions and scuff marks; Not enough to negate their use, but not what expected from a new product.

I used these in my physics classroom and they honestly worked better than the fancy long ones I already had. This made it affordable and easy for everyone to see the diffraction pattern given off by our various gas tubes.

TenÃa otros protectores de vidrio templado, pero no funcionaba bien el lector de la huella en pantalla. Con este protector de hidrogel el lector funciona perfectamente. La pantalla se ve con la misma claridad y la protección contra rayaduras es correcta. Un poco engorrosa la instalación, al tener que empapar las dos caras del protecto, y cuando parece que queda con manchas, al poco tiempo se seca todo y queda perfecta. Vienen dos protectores y yo sólo usé uno.
