k9 large plano convex lens hino 500

The front and rear surfaces of the plane Convex Lens are asymmetric. The plane convex lens can effectively reduce the spherical aberration, especially in the application of unequal object image distance. The best application is to place an object at an infinite distance (i.e. parallel light incidence) and place the image in the focal plane. The plane convex lens manufactured by our company has been sold to many countries and regions in the world and has won a good reputation in the international optical industry.

Material: K9, BK7, FS, UVFS, CaF₂, ZnSe

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.
