Abstract
The utility model relates to a high-power laser optical reflector with a light polarizing axis, particularly an optical reflector seat. The utility model comprises a base seat, a lens seat, an adjusting device and a cooling device; one surface of the base seat is provided with a cover plate, the cooling device and the lens seat, and the lens seat faces the inner side; light guiding holes are respectively arranged on two crossed oblique planes of the base seat opposite to the lens seat. The utility model is characterized in that the lens seat and the base seat can be rotated opposite to each other, and a locking device is arranged between the lens seat and the base seat; the positions of the light guiding holes enable a high-power laser beam to irradiate inwards to the radius of a lens deviating from the axis center of the lens. After the position of an incident point of a light polarizing axis of a reflecting lens is damaged, and after the lens seat is rotated for a certain angle, the lens seat and the base seat are mutually locked and fixed, and a light guiding system is accurately trimmed by the adjusting device. When a high-power laser beam irradiates the reflecting lens through the light guiding holes, the position of the incident point is a new and intact lens surface, and the reflecting lens can be reused, so the duration of service the reflecting lens is improved.
Description
Technical field:
The utility model relates to a kind of optical reflection microscope base.Particularly a kind of polarizing axis high power laser optical reflection microscope base.
Background technology:
At present, for laser technology being used for practice, need perfect light-conducting system, make laser beam according to the requirement of setting, have certain direction, therefore, perfect light-conducting system is indispensable in the laser technology.In light-conducting system, catoptron can be with the laser of incident, and with identical with the incident angle size, the direction of rotating respective angles reflects, thereby changes the direction of laser beam.Therefore, catoptron is vital parts in the light-conducting system.
In the use of laser machine, especially in the cut, must use powerful laser beam, this powerful laser beam, the energy height that carries, and the distribute power of light beam is peak shape, concentrates on the center of light beam.
When powerful laser beam enters light-conducting system, when inciding reflecting optics, because the power that laser beam carries is big, especially the center of laser beam has the energy peak district that concentrates more.Down conventional, the transmission optical axis of laser beam is coaxial with the center of reflecting optics, when powerful laser beam incides the center of reflecting optics, average peak power is higher in the center of reflecting optics, temperature raises, long-term work or when falling dust is arranged makes this place can cause lens surface to damage, so that scrap.
To the use of reflecting optics in the high power laser light beam light-conducting system, for planarity and the stability that guarantees that it is good, often the reflecting optics area of the catoptron of high power laser light beam is adopted greater than laser beam diameter 3-4 doubly about; And be provided with chamber in the back of reflecting optics, and in chamber, pass to chilled water, the heat of reflecting optics is conducted as early as possible, to reach good cooling, guarantee the request for utilization of reflecting optics.
The method that adopts the large tracts of land reflecting optics and adopt chamber to cool off, though reached the request for utilization of reflecting optics, but, because high power laser light beam incidence point is positioned at the center of laser mirror, after use a period of time, fault may appear in the center, in case this point forms fault, the full wafer reflecting optics have to be scrapped, and the reflecting optics of reflection high-power laser light beam costs an arm and a leg, therefore, cost is very high.
Summary of the invention:
The utility model aims to provide a kind of polarizing axis high power laser optical reflection microscope base, and it can make the reflecting optics of the high power laser optical mirror in the light-conducting system prolong serviceable life.
The utility model comprises pedestal, eyeglass seat, adjusting gear, cooling device; Wherein, The one side of pedestal is provided with cover plate, cooling device and eyeglass seat; The eyeglass seat is towards the inboard, is respectively equipped with light-conductive hole on two crossed ramps relative with the eyeglass seat on the pedestal.Between eyeglass seat and the pedestal, can rotate and be provided with locking device relatively; The position of light-conductive hole is incident on the radius of disalignment of reflecting optics the high power laser light beam.As Fig. 1, shown in 2,3.
Place high power laser optics to adjust control system the utility model, as the high power laser optical reflection microscope base of light-conducting system.
When the high power laser light beam is injected reflecting optics by light guide opening of the present utility model, because the incidence point of high power laser light beam is on the radius of the disalignment of reflecting optics, the center of circle of the axis deviation reflecting optics of laser beam forms polarizing axis on reflecting optics.
After the incidence point place of the polarizing axis of this reflecting optics damages, open bonnet, the rotating mirror bar after eyeglass seat rotating certain angle, will lock between eyeglass seat and the pedestal, and with adjusting gear light-conducting system carried out Precision trimming.When the high power laser light beam when the light guide opening toward mirror sheet, the fault of damaging on the reflecting optics has rotated to other position, the incidence point place be new, intact mirror mirror has promptly prolonged about one times the serviceable life of this reflecting optics.When rotating mirror bar once more, promptly prolonged about one times the serviceable life of this reflecting optics again.The eyeglass seat rotates repeatedly, and prolong several times the serviceable life with reflecting optics that can be relative.Because the utility model makes the high power laser light beam form polarizing axis on reflecting optics, makes after the reflecting optics anglec of rotation, can reuse, and has improved the term of life of reflecting optics.
In sum, the utility model is a kind of polarizing axis high power laser optical reflection microscope base, and it can make prolong the serviceable life of the high power laser optical mirror in the light-conducting system.

Fig. 2 looks for a left side of the present utility model, synoptic diagram is looked on the right side.
Fig. 3 is that the A of Fig. 2 is to synoptic diagram.
Among the figure:
The 1-pedestal, 2-eyeglass seat, 3-adjusting gear, 4-cooling device, 5-water delivering orifice, 6-water inlet, 7-cover plate, 8-light-conductive hole, 9-high power laser light beam incidence point, the axle center of 10-eyeglass seat.
Embodiment:
The utility model is used for CO
2On the laser machine, its laser power is 2200W, and requiring the angle of laser refraction is 90 °, make laser beam incidence reflection eyeglass after, on radius R, be positioned at and be slightly larger than beam radius r place and be formed into exit point, promptly reflecting optics is formed polarizing axis.After fault appears in this incidence point place, open bonnet, will lock with locking device behind the eyeglass seat half-twist and between the pedestal, and light-conducting system is carried out Precision trimming with adjusting gear.When the high power laser light beam once more when the light guide opening toward mirror sheet, the fault of damaging on the reflecting optics has rotated to other position, the incidence point place be new, intact minute surface has promptly prolonged about one times the serviceable life of this reflecting optics.The utility model as makes eyeglass seat rotation four times in this embodiment, will prolong four times the serviceable life of reflecting optics.
