Description of Ajax Scientific Concave Convex Diameter
Reversible concave and convex spherical mirror for demonstrating optical principles and effects for students. Outward curved surface forms an image of the reflected object that is slightly distorted and smaller than actual size. Inward curved surface forms an image of the reflected object that is upside down when past the focal point and magnified and right-side up before the focal point. Focal length is 200mm. Mirror is 75mm in diameter.
Thanks to my knowledge gained in practice, I find this optic tool to be quite disappointing. THE quality is subpar and doesn't meet my expectations. i was hoping for better accuracy and durability, but unfortunately, this product falls short..
This mirror is fine except it's a lot smaller than I expected. I paid over $9 for it and it felt like a compact makeup size. There's nothing special about that. On one side you see things bigger (concave) and on the other side you don't. So the price is definitely too high for this size. If they charge that much for it, it would be nice if they at least added some interesting science experiments to do with it.
