FIELD: laser technology.
SUBSTANCE: invention relates to a focusing apparatus for laser processing and can be used in various branches of the national economy for processing various materials. The apparatus comprises a body, a connector for connecting laser emission, and two mirrors, a nozzle for supplying compressed gas and a rotary protective cover with a compressed gas overpressure valve, installed in the body. For the passage of a beam, the first flat mirror is made at an angle to the axis, with a central hole. The second mirror along the path of the beam is made convex, reflecting the beam onto the first flat mirror, wherein the beam reflected from said mirror along the path passes the focusing lens and focuses on the material.
EFFECT: provided possibility of cutting materials remotely, leading to an increase in the efficiency of processing materials.
