BICONCAVE LENSES
Compare
Biconcave lenses (BCC) have generally symmetrical shape but can also have surfaces with different radii of curvature, especially if integrated in special optical systems. They have negative focal lengths and always form virtual images that are viewed through the lens; they also have the property of diverging light beams incident on ...

BICONVEX AND ASYMMETRIC LENSES BCX - ABL
Compare
Biconvex lenses (BCX) and asymmetric lenses (ABL), similar to PCX ones, have positive focal lengths combined with convex surfaces. The surfaces of BCX lenses have equal and symmetrical radius of curvature, while ABL ones have both convex surfaces but with different radius of curvature. In the latter case there is a special ...

PLANO CONCAVE LENSES PCC
Compare
Plano-Concave Lenses (PCC) have a first plano surface and a second concave surface that generate an overall negative focal length. They never form real images and they can be used for diverge an incident beam or, alternatively, to increase the focal length of a previously known system. As for PCX ones, PCC lenses provide a minimum ...

Plano-Convex lenses (PCX) have a first convex surface (positive) and a second flat surface that give them a positive focal length. They are suitable for the conjugation of objects place at infinite distances when used with the convex surface turned toward the object and the plane surface turned to the image. They are also used to ...

These lenses have positive focal lengths. They work best when producing real images at near infinite conjugates or where one of the conjugates is virtual. They outperform the equivalent equiconvex lens if the magnification lies in the range: m<-5 or m>-0.2. The optimum orientation for most application is with the curved ...
