Lenses are classified by the curvature of the two optical surfaces. A lens is biconvex (or double convex, or just convex) if both surfaces are convex. If both surfaces have the same radius of curvature, the lens is equiconvex. A lens with two concave surfaces is biconcave (or just concave).
Power consumption is the amount of input energy (measured in watts) required for an electrical appliance to function. This is opposed to power output which is a measure of the level of performance, of a heat pump for example.
the measure of the perceived power of light.
