6 Pcs Acrylic Glass Light Prism Optical Lens Triangular Semicircular Rectangular Concave Convex Mirror Len Physics Demonstration Tools Equipment for Physics Teaching Lab Reflection Refraction Science

At 41, I'm still just a big nerd at heart and I love learning. Physics and physics demonstrations never cease to entertain me and when I saw these lenses something in me just had to have them. I use a laser often for my astronomy outreach and I guess a part of me thought "now I can use my lasers for other fun things too" and share demonstrations with my young nieces etc.The kit is a nice mix of lenses to demonstrate a handful of light bending physics. The quality seems nice with no noticeable seams or blemishes etc. If I had to nitpick one thing about them I would have appreciated a slightly nicer way to keep them, like protective cloth pockets instead of just the cardboard envelope with the plastic slots. But, it suffices so it's not a big deal and it keeps the cost down.

These prisms have brought many smiles to my classroom. They helped my students see light refraction first-hand. However one of them did arrive chipped.Overall a good tool for modeling and would purchase again.

These were ok. Makes a tiny rainbow and it needs perfect sunlight to make it work. I purchased it for a lesson and it could not be used.

These prisms came in handy for my homeschooling. It was a great opportunity to go out in the sun and use the prisms to find rainbows. The material made it more difficult to see the rainbows than in higher quality prisms, but I also didn't have to worry about durability being an issue. Overall I have no complaints and they served their intended purpose.

These were just chunks of plastic with absolutely NO prism qualities AT ALL.100% scam.

Well, I feel a little silly about this one. I saw the word “prism” and assumed they would all cast different types of rainbows, so I jumped on it because I thought my daughter would enjoy trying it out. I guess it didn’t exactly help that there was a rainbow on the packaging. It seems the intention is to explore light refraction using lasers on this set, and I don’t own a laser pointer so that’s not really going to be possible for me. I was able to get some interesting effects using a flashlight but I’m pretty sure my kid would be more interested if the beam from the flashlight turned to rainbows.The bottom of the box marks out measurements and angles to study the changes to the light beam as it passes through each prism. I imagine this is a nice touch for the experiments.I was disappointed to see that two of the prisms had dark specks of a material I can’t identify floating inside of them. A third had scratches on the side. Obviously I’m not an expert about prisms but I’d have thought something you’re using to experiment with light refraction shouldn’t have impurities. I note it here for more knowledgeable folks to help them make a determination on whether this set will suit their needs.I tested them as best as I could using a little flashlight and was able to see some interesting effects, especially when I tried shining the light through different parts of each one. It might be a fun experiment for my daughter for that purpose, even if there aren’t any rainbows. I still think it would be preferable for them to be completely free of impurities but for our home use they’ll be fun to play with. My parents have a laser pointer at their house so we may take the set there sometime to see how the laser’s beam is affected by them too.

This set of prisms is really good to teach about the properties of light. It's a good thing my kids are insatiable nerds. I originally thought it would be a traditional set to project rainbows, I was wrong.As luck would have it, we keep a supply of lasers around and were able to demonstrate principals of light.Just make sure you know what you're getting and keep them in the case to avoid damage (acrylic can scratch, cloud and mar) and you'll be happy.

Points:+Comes with 6 different prisms+/-Affordable but not good quality+/-Can create rainbows, but very faintly+Box includes a printed protractor-Acrylic doesn’t have great claritySummary:I love small at home experiment kits. They make learning and teaching kids complex things a lot more exciting. The EUDAX acrylic light prism set is affordable which makes it more accessible. The problem is that the acrylic isn’t of high quality, due to a lack of clarity it makes getting that classic prism rainbow difficult. I was able to get it to work, but it was very faint.If you’re new to prims just be aware that to get a rainbow the light must be concentrated. Ideally you’d have a special light for this experiment. Most of us don’t. You can however make one using black paper and your phone light. Cut a thin slit in the black paper and hold in front of your phone light with the lights off. You can concentrate a smaller diameter beam and at the right angle you get that cool rainbow.The problem here was that the acrylic isn’t of great quality. It’s a little cloudy (or at least unpolished) so it makes getting all that light through and refracted into a pretty rainbow difficult. Some of the light is absorbed through the opaque acrylic so it’s not as bright as you would want for a great rainbow effect. Maybe if these were polished better or perhaps molded better they’d be great. As is they kind of work so if you’re interested in this experiment you’d likely want something with better clarity, if you just want to bend light they’re work alright.
