Optisches Glas-X-Cube-Prisma

WOW! I was not expecting such a beautiful object! When I got the package, I couldn't understand what I had ordered that was so heavy. I was so pleasantly surprised to find this glass cube. I have ordered some similar to this before; one cube was made of acrylic so it was lighter weight. Another polyhedron was glass but much smaller, so they were both lighter weight. Being the size that it is and made of glass, it gives it gravitas and makes it more of a piece of art. I absolutely love it! It is mesmerizing. It makes a good paperweight or curiosity for your sideboard or coffee table. The pictures in the listing do not do it justice!

Interesting colored cube, good conversation piece. Good quality.

I really like it.Shine sunlight through it and move it around. Heavy piece of glass. Made in China.

I ordered thus because I lost all of my old prisms during a move. This cube was delivered in perfect shape, there is plenty of packaging. Definitely recommended

Exactly what I was looking for. This trichromatic cube is on the smaller side, but still demonstrated light refraction of different colors of light as you rotate the cube. My students were mesmerized. It was absolutely worth the cost. Now I want a 2nd one to show the secondary light refraction!

This is going to be a for an artist. I am not disappointed. It is glass, heavy and big enough to make an impact. I don't know how it works but it is so cool. This thing screams quality.

Fairly nice but it doesn't do as much as I hoped. If you get it in sunshine it does ok.

This hangs in a window that receives bright light in the afternoon. The pretty colors and lights that reflect in the room are fascinating to my two kitties. Sometimes I twirl it for them creating an exciting lightshow. Watching them playing with the lights entertains me too : ) : ) : )

Others like this just have a membrane on the faces which peel off overtime. This one it's actually the coloring of the glass/is atomically formed to the surface?

I have this in my office, iridescent is one of my favorite colors so this make me happy through out the day.

This thing is way more beautiful than it shows in the pics! Do not expect a traditional pure prism, this is not that. Each facet has filters that filter out and reflect a specific wavelength/color of light. Sometimes you can witness TIR or Total Internal Reflection too if you have the angle right, which is super cool to me as an optics nerd (Schmidt-Pechan vs Abbe Koenig prisms in binoculars, telescopes, etc) Its just a really pretty trinket, but not a traditional "rainbow" prism so dont expect that. I would buy again, I got the 25mm cube, thinking about getting the polyhedron now. It is so beautiful in sunlight and fun to play with different colors of lasers. But be careful in sunlight or with lasers! Wear eye protection! Some reflections can catch you off guard and are not necessarily what you would expect! Be careful.But its beautiful and packaged nicely.Only room for improvement would be if it came in a small velvet/microfiber sack or with a cloth to keep fingerprints off. Or a 3 pronged stand on which to hold it up, off centered.So cool to watch it in the light and turn it and see from different angles.

Given as gift, my grandson is really happy with the clarity and response of the refraction. Great quality and price, quick delivery.

You can get some very impressive displays of color with a strong LED flashlight.

I love these objects that manipulate light waves into many colors both from a scientific view and for just the magical wonder that it elicits. It is cheery to have these on my desk.

this doesn't have the same effect, as an actual prism, but it's really cool, so i kept it...
