About This Product
A concave lens is thinner at the centre than at the edges. It spreads a parallel beam so that the rays appear to come from a point on the incoming side, and it always forms a virtual, upright and diminished image. In school physics, concave lenses are used on an optical bench to study image formation and, together with a convex lens, to find focal length. They are also the standard example of the lens used to correct short sight. The Concave Lenses can be supplied and exported to buyers in São Tomé and Príncipe, Tunisia, Tajikistan, Gabon, France and Jordan.
