Refraction

Materials such as white glass and thin paper scatter the light rays in many random, unpredictable directions as they pass through. This is called diffuse transmission

that strikes it: it can transmit, absorb, or reflect that photon.

Absorption and reflection are both more major influences on

Transmission

direct transmission, in which light passes through a material in a predictable path.

Chromatic aberration is the most pernicious optical problem found in telephoto lenses. There are others, including spherical aberration, astigmatism, coma, curvature of field, and similarly scary-sounding phenomena. The best solution for any of these is to use a better lens that offers the proper degree of correction for aberrations, or stop down t
