Plano-Convex Lenses is widely used in optical display systems, projection optics systems, imagining optical systems, and laser measurement systems.
It is best to use where conjugate point– object distance, S or image distance S is more than five times of the other.
This lens is almost the most super form for both collimating a point source and focusing collimated light.
Applications:
●Optical Display Systems
●Projection Optics System
●Imaging Optics Systems
●Laser Measurements Systems
