Product Description:
Plano-Concave Lenses
Plano-Concave Lenses bend parallel input rays so they divergefrom oneanother on the output side of the lens and hence have a negativefocal length. The spherical aberration of the Plano-Concave lenses is negativeand can be used to balance aberrations created by other lenses. Similar to thePlano-Convex lenses, the curvature surface usually faces the largest objectdistance or the infinite conjugate to minimize spherical aberration.
