FIBER-OPTIC SYSTEM FOR PROCESSING OF DETAILS AT A REMOVE FROM LASER INSTALLATION

Fiber-optic system is applied as a compound of laser equipment utilities; it allows processing of details that are at a remove from the radiation source and in hard-to-reach places.

 

The fiber-optic system includes an input device for laser radiation into optical fiber 1, optical fiber 2, a laser output device from optical fiber 3, a visual observation channel 4, a video camera with a monitor 5, and an illumination system 6.

Application of this system allows controlling the processing by means of a monocular device and a device for the output of the processed zone image to the screen, resulting in effectiveness and quality increase od laser processing of the details in comparison with the existing analogues.
Technical characteristics of the fiber-optic system in the laser system are given in the table.
