As shown in fig. 1, the present embodiment provides a specific implementation of an incident light path deviation fine tuning device for an optical fiber, including a mounting base 2, where the mounting base 2 is a rowland circular rail connected to a bottom plate 1, and a mounting position is provided above one end of the rowland circular rail, where the mounting position is used for installing an optical fiber base 3, and the optical fiber base 3 is used for installing an optical fiber device 4.

As shown in fig. 2, the optical fiber holder 3 is slidably connected to the mounting position, the mounting seat 2 is provided with an adjusting screw 5 which horizontally penetrates through the optical fiber holder, the adjusting screw 5 is slidably connected to the mounting seat 2, the adjusting screw 5 penetrates through the mounting seat 2 and then is in threaded connection with the optical fiber holder 3, specifically, the thread of the adjusting screw 5 is 0.3mm pitch, and when the optical fiber holder 3 is slightly shifted, the relationship between the number of turns of the adjusting screw 5 and the adjusting distance of the optical fiber holder 3 can be calculated according to the pitch of the adjusting screw 5, so that the adjusting distance of the optical fiber holder 3 is conveniently controlled, and the adjusting efficiency is improved.

As shown in fig. 2, an elastic member 6 is sleeved on the adjusting screw 5, and specifically, the elastic member 6 is a compression spring. The compression spring has an elastic force for driving the optical fiber base 3 to move towards a direction far away from the adjusting screw 5, and under the action of the compression spring, the adjusting screw 5 always extends towards the optical fiber base 3, so that the position of the optical fiber base 3 is kept.
