Amlong Crystal 2.5 inch Optical Glass Triangular Prism for Teaching Light Spectrum Physics and Photo Photography Prism, 60mm

We purchased this prism for our toddler grandson. He's a curious fellow, and the chance to experiment with light refraction is right up his alley. The prism is high quality. Well cut and polished. Sturdy too, even as our toddler "heavy hands" it. The prism produces clear, defined, and colorful spectra. What else could you want?

This was a good quality prism and you can see the great rainbows that it makes in the picture. It comes in a nice protective case and would definitely buy again.

Has a defect in it making the refraction from certain angles have a shadowy blob, other than that great tool.

I use this for a toddler to entertain and learn colors. Price is good and a good deal of fun. I buy many toys on Amazon that, under adult supervision, help a toddler learn how objects work, and this is one of the items. Playing with real objects rather than just digital screens is worthwhile.

Good quality glass. Works well as a ROYGBIV color separator using either sunlight or flashlight. Hint: shine the light through a slot to get the best color stripes. Not exactly a “toy”, Amazon. It’s a scientific instrument!

Tried a few times with a flashlight to no avail....hard to get sunlight through it i guess we'll try again (even on a sunny day, even with sunlight coming through a window) guessing you have to catch a specific ray which isn't always easy. It's clear and fun to play with but edges are a little sharp...

Seems good quality and will separate light into a rainbow when adjusted properly. It's a lot harder to achieve than those decorative teardrop style, where you just hang them and they throw rainbows when the sun hits them, but this style is better for showing how the light is bent.

I purchased this to enable my grandson (age 9) to understand the composition of light. I have placed it in beams of sunlight several times at different angles and only managed a small patch of full spectrum light. I was expecting a nice display of the spectrum like I use to receive from cheap prisms in science kits when I was a child. Sorry this was not what I was expecting.
