Abstract
The utility model discloses a girdling light guide system, which comprises a laser, a reflecting mirror, a scanning oscillation mirror and a collecting mirror. The utility model is characterized in that a telescope composed of two lens is arranged between the laser and the reflecting mirror; the focus points of the two lens are in the same axial cord; the interval of two focal lengths is 0.5 mm to 40 mm. The utility model has the advantages that the focus points of the two lens are in the same axial cord, and the interval of the two focal lengths can be adjusted in a range of 0.5 mm to 40 mm; thereby, the light spot can be controlled at a required size when a flight light path is in a definite distance range.
Description
Technical field
The utility model relates to a kind of light-conducting system, especially a kind of shape light-conducting system with a tight waist that is applicable to the processing of laser flying light path.
Background technology
Existing flight light path is in Laser Processing, transmit on the general plane that all forms on the space, because the existence of laser beam divergence, therefore, in actual use, light path produces disperses, and becomes big gradually at the far-end hot spot, so that can't all enter the speculum of processing, so just limited the size of working face.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of spot size of flight light path system that makes to can be controlled in the interior shape light-conducting system with a tight waist of allowed band.
The technical solution of the utility model is: a kind of shape light-conducting system with a tight waist, it comprises laser instrument, speculum, scanning galvanometer and condenser, be characterized in, between lasers and mirrors, be equipped with the telescope of forming by two lens, the focus of described two lens is on same axis, and two focal length separations are 0.5～40mm.
The beneficial effects of the utility model are: because the focus of two lens is on same axis, and two focal length separations are adjustable in 0.5～40mm scope, and flight light path can make hot spot be controlled on the size that needs in certain distance range.
Description of drawings
Fig. 1 is shape light-conducting system light path principle figure with a tight waist.
The specific embodiment
By shown in Figure 1, a kind of shape light-conducting system with a tight waist, it comprises laser instrument 1, speculum 3, speculum 4, scanning galvanometer 5 and condenser 6, be characterized in, between laser instrument 1 and speculum 3, be equipped with the telescope of forming by two lens 2, the focus of described two lens 7,8 on same axis, two focal distance f
1, f
2Separation L is 0.5～40mm.The light that laser instrument 1 sends is through telescope 2, through behind the speculum 3,4 again behind the variable scanning galvanometer 5 of reflection angle to condenser 6, regulate by telescopical two focal lengths of lens, make the light between three speculums with a tight waist, make the controlled amount system of the hot spot behind condenser.
