WebPlano-Convex lenses are the best choice for focusing parallel rays of light to a single point. They can be used to focus, collect and collimate light. The asymmetry of this lens shape minimizes spherical aberration in situations where the object and image are located at unequal distance from the lens. WebPlano-convex lenses have one convex (positive) surface and one plane surface. They are often used for focusing collimated or near collimated light in applications where focus spot size is not critical. Plano-concave lenses have one concave (negative) surface and one plane surface. Main applications are diverging collimated or near collimated light. sly stone family affair lyrics and chords
