biconvex lens
Description
The biconvex lens is a type of convex lens, which is thicker in the middle and thinner at the edges. This characteristic allows it to correct defects that arise from both flatness and curvature. Another attribute of the biconvex lens is its spherical surface, which enables light to travel parallel to the axis.
The biconvex lens is, as you would expect, convex on both sides. A biconvex lens has two foci and when used in combination with a plano-concave lens one of the foci is a real focus and the other is an apparent focus.
For astronomy, giving better sharpness and contrast. In photography, giving extra depth of field. Also used in binoculars and telescopes.
