▎ 摘 要
NOVELTY - The separated type zero-clearance combined lens has a first lens, a second lens, a lens seat bracket of single layer graphene film and a fixed lens. The single layer graphene film separates first and second lenses without air gap. USE - Separated type zero-clearance combined lens for optical imaging system. ADVANTAGE - The processing of the combined lens is made convenient and reduction in cost of the combined lens is achieved. The production efficiency of combined lens is increased. The combined lens is made stable for a long time. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of separated type zero-clearance combined lens.
