Product description
Glass Plano convex lens is a high-quality glass Plano convex lens made by fine grinding of high-quality glass. Because of its high stability and good performance, it is widely used in different high-precision optical elements and optical lenses for industrial scientific research, such as national defense, military industry, precision medical instruments and so on. The glass Plano convex lens is composed of a plane and a sphere. When focusing, the collimated beam should be incident on the curved surface of the lens, while when collimating, the point light source should be incident on the plane of the lens, the beam converges on the rear focus, and the point light source can also be converted into a collimated beam.

Example with BK7 material:These N-BK7 Plano-Convex lenses are available uncoated or with one of five antireflection coatings (-A, -AB, -B, -C, or -D), which reduces the amount of light reflected from each surface of the lens (see the Selection Guide table below for coating option). Since approximately 4% of the incident light is reflected at each surface of an uncoated substrate, the application of an AR coating improves transmission, which is important in low-light applications, and prevents the undesirable effects (e.g., ghost images) associated with multiple reflections. Having optics that are AR coated on both surfaces is particularly desirable for applications utilizing multiple optical elements. Please see the Graphs tab for additional coating information.
