A plano-convex lens is a positive focal length lens with a plane on one side and a convex on the other. It is used to concentrate parallel light, or convert point light sources into parallel light. Widely used in telescope, microscope, sight, laser, optical fiber and other products.H-K9L (N-BK7) plano-convex lenses are often used to focus parallel light or collimating point light sources and have excellent transmittance from visible to near infrared (350-2000nm).H-k9L is an commonly used optical glass when you do not need the additional advantages of uv melting quartz .In the convergence of light, if the absolute magnification is lower than 0.2 or greater than 5, usually choose plano-convex lens.When the magnification is between 0.2 and 5, a double convex lens is more suitable.To reduce spherical aberration, parallel light should be incident on the surface during focusing.

Optical Mirrors are used for beam turning, interferometry, imaging, or illumination.Using polished glass or metal as the substrate, the light beam hits the surface to form mirror reflection.In order to obtain as much reflected light as possible, the substrate is often coated ...
Plano-Convex lenses have positive focal lengths, converge incident light, and from both real images(as might be focused in a piece of paper), and virtual images(as are seen through the lenses when they are used as magnifiers).They are widely used in telescopes, collimators, ...
