12 Oct 2009 Lenses have many applications ranging from the simple collection of the scanning of laser beams to precise imaging and image transfer 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.
The Double Convex Lenses are made from BK7 material, which are manufactured with an identical convex surface on both sides of the lens. The Double Convex lenses have positive focal lengths and form both real and virtual images. |
