Double-Convex Lens
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.
●Beam Expanders
●Projection Optics System
●Imaging Optics Systems
●Optical Viewers
●Optical Character Readers
