Plane Convex Lens is one of the most widely used lenses to meet different high-precision optical components and optical lenses for industrial research, such as defense, military, precision medical instruments, etc. The principle of a flat convex lens is to aggregate parallel light or to convert a point light source into parallel light. The flat convex lens is composed of a plane and a spout, the collimated beam should be incident to the surface of the lens when focusing, and the collimation point light source should be incident to the plane of the lens, the beam will consort in the rear focus, or the point light source can be converted to a collimated beam. Our company has manufactured flat convex lens has been sold to many countries and regions around the world, and in the international optical community to obtain a good reputation.

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.
