Specific embodiment
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
It puts and is implemented, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is unlimited
In following embodiments.
A kind of light channel structure of optical fiber end face detector, including optical path pedestal 1, objective tube 3, light splitting lens barrel 2 and condenser
Cylinder 4 is provided with object lens channel 31 and spectroscope channel 21 in the optical path pedestal 1, and the objective tube 3 is telescopic to be installed on institute
It states in objective tube 3, the light splitting lens barrel 2 is installed in spectroscope channel 21,2 hollow design of light splitting lens barrel, is divided lens barrel 2
It is provided with optically focused lens barrel 4 in internal cavities, light source 5 is provided on optically focused lens barrel 4.Due to various, light is by anti-
It penetrates after refraction when eventually falling in imaging system, facula position and fiber end face the imaging often not heart in the picture, sometimes image
Image blur can not obtain clear available image.This programme is by the way that each influence such as condenser, spectroscope, object lens to be imaged
Critical component be arranged to adjustable form, to realize " fine adjustment " of all parts, finally make the image clearly obtained
It can use.
It is provided on optical path pedestal 1 and adjusts notch 12, the adjusting notch 12 is set on 31 side wall of object lens channel, described
It is provided on objective tube 3 and adjusts strut 8, adjusted strut 8 and connect with the mandril 61 of adjusting handle 6, the adjusting handle 6 is set to
On the outer wall of optical path pedestal 1.The rotation of adjusting handle 6 can make mandril 61 elastic, so that the position to objective tube 3 carries out essence
True fine tuning forms clear image to focus.Total design is simple, easy to process, easy to repair, at low cost
