Review on Ajax Scientific Optical Equilateral Length: Precise Measuring Tool for Optical Experiments by Jerome Pritchard

Very nice glass prism. It's very crisp and I really liked the smooth edges and I don't have to worry about cutting myself with it. It worked great for my purposes! But it doesn't refract light nearly as well (doesn't create rainbows) as I would like. But since it worked for my project I still give it 4 stars as it's good quality!
