Single equilateral prism measuring 4" (100mm) long. Each face measures 1" (25mm). Made of durable, highly polished acrylic. Excellent tool for optical experiments, and can be used for photography lighting effects as well. Prisms will create a nice rainbow (even in room light) by using the simple led light of a smart phone. User will need to create a small slit in a black piece of paper and use that slit in front of the led which will create a light ray. The prisms will then refract the white light and create a nice rainbow on a target away from the prism. The farther away you move the target the bigger the rainbow gets and the more distinct colors the user can see. A great tool for teaching optics or for just having fun.

Worked well for my kid’s science fair. I wanted glass but it was prohibited by the school, but it ended up not mattering. This prism does a great job. The bigger issue is finding a good light source since so many flashlights these days are LED. I ended up buying an old school D cell xenon mag lite which did the trick.

A fun distraction for home or office, the prism splits white light into a rainbow. It is light weight and sturdy. It would be excellent in a classroom. No criticisms about this product.

This is well manufactured- my only complaint is that it is a bit pricey for non-glass.

Purchased this for my 7 year old great grand daughter and she seems to like it.But you have to tilt it very accurately or it will not produce the rainbow of colors from the sun.
