They work wonderful and are as advertised. However the shipping method for them is pretty lack luster. They came in these flimsy cardboard boxes and one of my prism ended up chipping. Because I'm using these for a classroom I cannot let kids handle or maneuver the broken one.

Bought to use for experiments in the Physics unit with my Grade 8 class. Great quality for the price. Prisms refract sunlight well and all students were able to see a rainbow.

I used a glass prism to refract the sunlight and disperse this intense rainbow 🌈 onto my clear quartz elongated alien skull. 💗 💡 Easy to use and educational for examining basic properties of light, especially refraction (Snell's law) for glass and air combined with dispersion. Output color is as vibrant as shown if using sunlight. Great value and quality for money, since the product shipped in perfect condition.

Bought them to bend infrared to my TV which sits a little too far back to get a good signal from my remote. Works exactly as I anticipated.

Not a prism like I used to have, this one is just glass. Forgot about it because it fell behind other items. Trash.

Very good quality, no rough edges, well packaged. I taught the grandchildren a brief mini lesson on the spectrum of light and now they keep these in their backpacks and use them frequently. Great for car rides!

I bought these because I was reminded of the prism and the spectrum produced I saw in science class many decades ago. In my second childhood, I am occasionally fascinated by the spectrum produced by these prisms. For best enjoyment, put them in a window and darken the room as much as possible while still keeping direct sunlight on the prisms. Put a piece of white paper in the location of the spectrum to see it in it's full glory.NOTE ON LIGHT SOURCES: Almost all artificial lighting these days DO NOT contain much of a spectrum at all so you will not see a spectrum with any prism. A halogen or LED flash light will not produce a spectrum. I cannot say 100% about fluorescent or incandescent lights since I do not have flashlights with them, but I doubt they have much of a spectrum either.

I am satisfied with the prisms but, there was no protective material around them when they arrived. They were in a thin envelope. Amazon distribution people dropped the ball on this one!

I tutor a 14 year old boy in the eighth grade. His science class is very weak so I purchased these prisms to illustrate refraction of sunlight. I stood with the Sun behind me, put the prism over my shoulder and directed the spectral display onto the shadow in front of me. It was beautiful- Violet, Blue , green,yellow, red.Note- these things are glass and the corners are very fragile. Don't just toss them around they will chip easily.

I bought these to see if they would be good for teaching about prisms. Particularly about refraction of light. But if you look at the reflection of a line, or look through the prism at a straight line. (I used the edge of the white background on this screen) you will see that the whole is curved and not straight. The colors spread out as they should - but the whole line is curved - STRONGLY.So I think they took hot glass and forced it into a mold at the lowest temperature possible. Then polished the surface. So what happens (pretty sure) is the optical properties change from one end of the prism to the other.These are CHEAP. They have the right shape. They are clean. They will more or less refract single rays of light and spread out a beam of light for verbal demonstrations.Would this be a good starting point for any quantitative experiment - I don't think so. Unless you were teaching modeling and calibration. Then, the fun is taking a really badly made device (a prism is an optical device) - measure it, model everything, and then use the computer to standardize the poorly made device. Use measurement and computers to fix the too quick way they made this.I think all they need to do is heat the glass to a higher temperature, and be careful to cool it uniformly. I think these guys sell short prisms. I will see if the short ones are not so distorted.Such a curvature could come from strain left in the glass. But it can be a slowly varying index of refraction. If you were teaching gradient index things, it might be a good example. Ask the students to use the gradients for something practical.Hold the prism in two hands with the triangular shape pointing up. Look through the top (thin part) of the prism at the bottom of the computer screen. Slowly lift the prism until you can see the bottom of the screen. The line of your eye through the prism will be pointing above the screen. It should be fuzzy with the colors spread out. Notice how strongly it curves from one side of the prism (right to left, left to right)Hold the prism vertically, and turn it slowly around the vertical axis. Look for an image of the edge of the screen. It should have vivid colors. BUT it won't be a straight line. In mine, the apparent distance of the "straight" edge of the screen from long axis of the prism changes from top to bottom and is also curved. Wish I could show you. Will see if I can find a camera somewhere.Richard

These prisms work great with sunlight.Indoor lights (I have LEDs) are not bright enough and/or maybe don't produce the whole spectrum to be seen with these prisms.
