Double Convex Lens

Double Convex Lens (aslo named Bi-Convex Lens) is most suitable where the object and image are on opposite sides of the lens and the ratio of the image and object (conjugate ratio) distances is between 0.2 to 5. It is used in beam expanders,. projection optics systems, optical viewers, imaging optics systems, optical character readers etc ...
