Wide-angle optical fiber preparation device for hard tube lens

Abstract

A wide-angle optical fiber preparation device for a hard tube lens comprises a base, a positioning shaft sleeve is fixedly installed in the middle of the upper surface of the base, a motor containing groove is formed in the bottom of the positioning shaft sleeve, a mold column hole is formed in the positioning shaft sleeve, a rotating motor is arranged in the motor containing groove, the rotating motor is fixedly installed above the base, and a mold column is installed in the mold column hole. The lower end of the mold column is fixedly connected with the driving end of the rotating motor through a key groove, an arc groove is formed in the upper end of the mold column, a positioning plate is fixedly installed at the upper end of the positioning shaft sleeve, and an optical fiber guide hole is formed in the middle of the positioning plate and corresponds to the arc groove in position. The device overcomes the defects in the prior art, the driving end of the rotating motor drives the mold column to rotate in the mold column hole, then the end of the optical fiber is ground in the arc groove to form a semicircular end face, and therefore the wide-angle effect of the end of the optical fiber is achieved.

Description

technical field [0001] The invention relates to the technical field of optical fiber preparation, in particular to a wide-angle optical fiber preparation device for hard tube mirrors. Background technique [0002] With the continuous popularization of high-definition cameras, because high-definition image signals have higher requirements on the transmission rate of transmission cables, the use of cables to transmit endoscope image signals has gradually changed to optical fiber transmission, that is, the transmission of optical signals, so as to meet the Higher transfer rate requirements. [0003] In the past, the end face of the optical fiber was usually flat, so that when the light was transmitted through the optical fiber and then exported from the end face, it was limited by the limitation of the refractive index of the material of the optical fiber itself, and the structural limitation of the flat end face, which made the viewing angle of this kind of display quite compa...

Problems solved by technology

[0003] In the past, the end face of an optical fiber is usually flat, so when the light is guided by the optical fiber and then exported from the end face, it is limited by the refractive index of the fiber itself and the structural limitation of the end face being flat, which makes the viewing angle of this kind of display comparable. narrow
