Optical double convex sphere mirror is a Cylindrical Lens sheet including an incident surface and an exit surface, which is characterized in that the focal length in the middle of the lens surface is long and the focal length at the end of each lens surface is short. Cylindrical lens is mainly used to condense light from point light source or transmit images to other optical systems. The lenticular 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

Example with BK7 material:These N-BK7 biconvex 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.
