Review on Round Double Concave Optical Glass Science Education by Jake Larson

Thanks to my knowledge gained in practice, this Double Concave Optical Glass has become one of my favorite tools for SCIENCE education. The glass has high-quality construction and can easily be used to demonstrate principles of optics and light reflection. Due to its small size, it may not be suitable for large classroom demonstrations .Nonetheless, it's a useful tool for personal experimentation and provides a hands-on approach to learning. Overall, I highly recommend it!
