A kind of grinding device for optical fiber lens with adjustable radian

Abstract

The invention discloses a radian-adjustable optical fiber lens polishing device, comprising a worktable, a backboard and a fixed screw rod. A bearing on the worktable is connected with a bidirectional threaded rod, and a limit ring is fixed on the bidirectional threaded rod. The end of the threaded rod is fixed with a hand wheel, and at the same time, the two-way threaded rod and the movable frame are connected to each other, the fixed screw and the cylinder are connected to each other, and the bearing at the end of the fixed screw is connected to the fastening plate, and the fastening plate is fixed with a rubber pad At the same time, a slider is fixed on the fastening plate, and the slider and the workbench are connected to each other. The optical fiber lens grinding device with adjustable radian adopts a movable adjustment grinding mechanism, which can realize the adjustment of the inclination angle of the grinding plate, and then realize the processing of conical optical fibers with different radians, and can realize the processing of optical fibers of different sizes through the distance adjustment mechanism. , and cooperate with the clamping device with the pre-positioning structure, which can effectively avoid the deviation in the clamping and fixing of the optical fiber.

Description

technical field [0001] The invention relates to the technical field of optical fiber lenses, in particular to a polishing device for optical fiber lenses with adjustable radian. Background technique [0002] Fiber lens refers to the processing at the end face of the fiber to make a specific lens shape, thereby forming the change of the optical path or the conversion of the mode. Spherical and conic, etc., are widely used in various fields at this stage. [0003] With the development of society and the advancement of science and technology, the application range of fiber lenses is becoming more and more extensive, and conical fiber lenses have strong light-receiving ability, so they can be used in LDs with circular or approximately circular output beam cross-sections. , DFB and VCSEL, etc., and high-precision conical fiber lenses can also be used in medical laser microsurgery systems and micro-illumination systems, etc., so the demand for conical fiber lenses increases.
