Detailed Product Description

Double-Convex Lens, also 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 etc;
Double-Concave Lens, also named Bi-Concave Lens, is used to divergent light. The Bi-Concave is best used when the input beam is converging. It is used in beam expanders,. Projection optics systems, optical viewers and optical charater readers etc;
