Great cheap prisms for fun and photography

They are definitely effective at spreading the spectrum of light, even with lower quality LEDs and broader spectrum halogens. But as always, the most impressive results come from angled and focused natural sunlight. I recommend them to parents and children, as well as broken artists and photographers. However, they are not the most durable. The largest prism in my order arrived with a few broken edges, due in part to the skinny seal.

Pros
  • Great overall performance
Cons
  • Doubtful

The lowest quality prism ever made!

In order for light to be refracted evenly and consistently through an object, that object must have no defects throughout its composition, otherwise it will distort the bandwidth of light and cause the visible spectra within individual Wavelengths can be wavy and curved. Through the acrylic triangle I get three bright reflections of white light from each source, and if you're lucky and in a dark enough place to find it, there's also a fuzzy spectrum that's not even decipherable due to…

  • beautiful thing

GARBAGE! They are non-refractory and non-refundable.

NO RETURNS. I was hoping that these prisms would be a good teaching aid for my child who is now asking questions about what creates rainbows and similar things related to refraction. These don't break! Therefore they are useless to me, and then I find that they are irrevocable. I wonder how Revain can sell a $9 item that honestly costs less than half that amount through their own fulfillment center and not back it up. I estimate over 90% of buyers buy them to conduct the experiments I have in…

Pros
  • New
Cons
  • Slightly torn
