Amlong Crystal2.5 inch Optical Glass Triangular Prism for Teaching Light Spectrum Physics and Photo Photography Prism, 60mm

I had no specific use for a prism other than sheer curiosity after finding the one I had 25-30 years ago as a kid. It was acrylic and a bit dulled up, like what happens to car headlights. This came in the mail promptly. It IS solid glass and is much more solid. I was using a small AA Maglite to try to get a spectrum Dark Side of the Moon style and what I got was... ok. The next day, I held it in the direct sunlight of a window and it gave off a deep, brilliant spectrum. The colors were enhanced beautifully from the red to the indigo and violet. I held it side by side with my old acrylic one and the glass prism definitely worked much nicer. I imagine that being glass, it would scratch or break easily, so it does come in a padded storage box with a soft liner. Glad I purchased it. Pretty cool conversation piece. Supposedly, a right angle prism works nicely too and I may jump on one too.

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?

Takes some work to get the light to bend just right but it makes a very vibrant rainbow, albeit a narrow one.

I got this for teaching a unit on light and color, and I wasn't sure we'd get it to work for us, living in the PNW where the sun is usually behind clouds. However - it worked beautifully! We were able to make many rainbows almost immediately. It also came packaged well in a box that is nice for storage.

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...

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.

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.
