sapphire optical glass lens, rod lens

Sapphire rod lens is precision-engineered from monocrystalline aluminum oxide, combining exceptional mechanical strength with broad-spectrum transmission from 0.15-5.5um Sapphire rod is specialized optical component designed for handling line light spots or extreme environments. Accordingly shape it's a cylindrical rod lens, two ends polishing or cylindrical surfaces polishing or all polishing as customer's demand. Rod lens belong to cylindrical lens, it has curvature in only one direction, it can not converge the light into a point, but is a line generator. Endoscope rod lens is typically used to focus incoming light to a line, or to change the aspect ratio of an image *The diameter of a rigid endoscope is usually only 2-10mm, and the internal space is extremely limited, making it impossible to accommodate a complex multi-lens assembly, so the rod lens is the best choice. *Image quality requirements: The rod-shaped lens is precisely ground on both ends( flat end or slightly convex), w…
