Wholesale Optical Flat Convex Concave Lens optical lens Telescope Mirror Lenses
Plano concave lens are with negative focal lengths and they can be used to diverge collimated beams; in this case, the curved surface should face the source in order to minimize spherical aberration. In addition, they can be employed to offset the effects of spherical aberration caused by other lenses in an optical system. Because the spherical aberration of the Plano-Concave is negative, it can be used to balance the aberration of other lenses.
