Plano-Concave Spherical Lens
Description
Plano-Concave Lenses are the best choice where object and image are at absolute conjugate ratios greater than 5:1 and less than 1:5 to reduce spherical.Plano-Concave lenses bend parallel input rays so they diverge from one another on the output side of the lens and hence have a negative focal length.The spherical aberration of the Plano-Concave lenses is negative and can be used to balance aberrations created by other lenses. Similar to the Plano-Convex lenses,the curvature surface should face the largest object distance or the infinite conjugate (except when used with high-energy lasers where this should be reversed to eliminate the possibility of a virtual focus) to minimize spherical aberration. Atoptical provides these lenses with the material of BK7, fused silica ,Si,Ge,CaF2,or other optical glass and crystal, etc.

Frequently Asked Questions
Plano-Concave Spherical Lenses are used in laser optics, OEM, vision, and metrology applications.
Plano-Concave Spherical Lenses are made of BK7, fused silica, Si, Ge, CaF2, or other optical glass and crystal.
The curvature surface of Plano-Concave Spherical Lenses should face the largest object distance or the infinite conjugate (except when used with high-energy lasers where this should be reversed to eliminate the possibility of a virtual focus) to minimize spherical aberration.
The focal length tolerance of Plano-Concave Spherical Lenses is +/-2%, +/-1%, or +/-0.5%, depending on the precision level.
