A flat convex lens is a type of lens that is convex on one side and flat on the other. Its materials include K9 glass, fused silica, zinc selenide, zinc sulfide, germanium, silicon, lithium fluoride, magnesium fluoride, calcium fluoride and barium fluoride. So where is the O point of the planar convex lens?
The O-point of a planar convex lens usually refers to the optical center position of the lens. In a lens, light rays do not deflect when passing through the optical center, and their direction is the same as the direction of incident light. For a planar convex lens, due to one side being a plane and the other being a convex surface, the specific position of point O may not be entirely at the physical center of the lens, but closer to one side of the convex surface.
The above is an answer to where the O point of the planar convex lens is located. We hope it is helpful to you. If you have any questions, please feel free to consult or leave a message online.
