Product Introduction
Ball Lens(K9,BK7)is optical glass beads of smaller diameter used to improve signal coupling between optical fiber, transmitter and detector to improve signal quality, also used in internal mirrors, barcode scanning, pre-processed materials for aspheric lenses, sensors, etc. Ball Lens(K9,BK7)has a shorter focal length and greater magnification than ordinary convex lenses, and its focal length depends on the refractive index of the material itself. Because of the short focal length behind the ball Lens, which allows for a greater reduction in the distance required from the ball Lens(K9,BK7) to the optical fiber, ball lensis primarily used in fiber optic applications.
