The Plano Convex Lenses are made from BK7 material. It presents a curved interface and a planar interface. They are for instance the microlenses situated on top of a wafer, but can also encountered in macroscopic optical systems. Their asymmetrical nature influences their properties of bending the light. Depending on their role in an optical system, their orientation has to be taken into account.
