Review on 🔍 Ajax Scientific Double Convex Bi-Convex Spherical Optics for Science Education by Anthony Grover

The upsides of this lens are that it produces a sharp image, the level of distortion I would expect from a $3 lens, and it's made of glass. The edges can be sanded but are rough. Its diameter is 50 mm. The bad side of the lens is that ajax Scientific's QC idea is to just read a magazine while random lenses are mummified in two layers of bubble wrap and industrial-grade plastic tape so nobody can see the object inside. correspond to the information on the labels. The actual focal length of 100mm versus 150mm makes it useless to me. If you just want a random lens or need to get rid of colonies of ants I think this isn't a bad $3 lens. But if you expect to get what the product promises.
