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

Niece liked it.

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.

I purchased a class set of these for an optics/ light waves lab. The first time I used them I noticed many of the optics are cloudy, making it more difficult to fully experience the hoped for phenomenon.

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.

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.
