The angle grinding penetrating loss and doing.
But in existing optical fiber component, there are problems that precision is low and be difficult to produce in batches.The end face of optical fiber relatively in
Mandrel line devises the angle θ, the angle that the general angle is 4 degree or more, however the angle causes in the deviation of light beam main shaft
Axis propagation, so as to cause the deterioration of precision, so that the light beam and benchmark A after collimation form the angle at an angle α, and light
The main beam of beam has the lateral shift of certain position with respect to optical axis；And band can be assembled and be used to small point precision to be subsequent
Carry out convenience, but put precision production generally the smaller the more difficult and design, is unfavorable for mass production.Therefore, a kind of precision is designed
It is high and be necessary convenient for the high point precision optical fiber component of batch production.
Summary of the invention
The purpose of the present invention is to provide a kind of high point precision optical fiber components, to solve mentioned above in the background art ask
Topic.
In order to solve the above technical problem, the present invention provides following technical solutions: a kind of high point precision optical fiber component, including

The inside for stating front cover is equipped with ceramic sleeve, and the ceramic sleeve is internally provided with ceramic insertion core, the ceramic insertion core it is interior
Adhesion has optical fiber at portion center, and the inside of the rear cover is separately installed with angle of wedge piece and lens, and angle of wedge piece is located at optical fiber and thoroughly
The middle position of mirror.
Further, one end of the ceramic insertion core is inserted into the inside of rear cover.
Further, angle grinding polishing is done in the end face of the ceramic insertion core 4.
Further, the angle of wedge sheet glass 6 is a kind of glass material, and there is opposite angle grinding to throw on light passing two sides
Light.
Further, the lens 7 collimate the light being emitted from fiber end face.
Further, the lens 7 are one of spherical lens, non-spherical lens or self-focusing lens.
Compared with prior art, the beneficial effects obtained by the present invention are as follows being: the present invention, it is fixed according to the refraction of geometric optics
Rule may make that the upper light beam propagated is changed to opposed optical fibers to the right to propagation to opposed optical fibers to the right, and then light beam is in angle of wedge glass
