Abstract

The utility model discloses a beam overlapping optical structure comprising a plurality of lasers or laser collimators with different wavelengths; a laser or laser collimator is corresponding to a group of WDM films and optical parallel plain blocks; the laser light produced by the laser or laser collimator becomes parallel beams through the WDM films; the optical parallel plain blocks are inserted between the laser or laser collimator and the WDM films to make the central lines of the parallel beams overlap and produce the overlapped beam. In this way, the WDM films can adjust beams of different wavelengths and ensure that the directions of laser lights of different wavelengths are parallel after being reflected and transmitted and the centers of the light spots are overlapped or close to each other as much as possible; the optical parallel plain blocks do not change the optical direction and only move the central lines of the beams to overlap the central lines of all beams to effectively overlap the laser beams of different wavelengths into one beam.

Description

A kind of beam optics structure of closing

Technical field the utility model relates to optical field, relates in particular to swash the combiner field.

Background technology often need be closed bundle with different wavelength of laser Shu Jinhang such as red, green, blue three colors in the laser display field.And usual manner fixedly can only roughly be realized being parallel to each other between the light beam behind the discrete laser instrument or vertical mutually, has influenced the effect that laser beam is closed bundle.

The summary of the invention the purpose of this utility model provides a kind of beam optics structure of closing, and its laser beam that one group of different wavelength of laser device can be produced is effectively synthetic a branch of.

For achieving the above object, the utility model comprises a plurality of have different wavelength of laser device or laser aligners, the corresponding one group of wavelength-division multiplex diaphragm of laser instrument or laser aligner (is a Wave Division Multiplexing diaphragm, the WDM diaphragm) and the optical parallel plain block, the laser that laser instrument or laser aligner send becomes the light beam that is parallel to each other through the wavelength-division multiplex diaphragm, the optical parallel plain block is plugged between laser instrument or laser aligner and the wavelength-division multiplex diaphragm, make the central lines of the light beam that is parallel to each other, produce and close light beams.

Like this, the wavelength-division multiplex diaphragm can be regulated light beams of different wavelengths, can guarantee that different wavelength of laser light direction when export transmission and reflection back is parallel to each other, and spot center is overlapping as far as possible or approaching; The optical parallel plain block does not then change the optical direction of laser, and the center line of a mobile beam makes the central lines of all light beams, thus realize different wavelength of laser Shu Youxiao overlapping close restraint into a branch of.

The laser vertical that the utility model also can make laser that last laser instrument or laser aligner send and previous laser instrument or laser aligner send, its directly the wavelength-division multiplex diaphragm by previous laser instrument or laser aligner carry out light beam and close bundle, can save 1 group of wavelength-division multiplex diaphragm and optical parallel plain film like this.

One group of wavelength-division multiplex diaphragm of the present utility model and optical parallel plain block can adopt a pair of concavo-convex globe joint carry out continuously every or the bonding or the welding in less gap fixing, can obtain temperature performance preferably.

Description of drawings is described in further detail the utility model below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of another embodiment of the present utility model;

Fig. 3 is wavelength-division multiplex diaphragm of the present utility model and the fixing structural representation of optical parallel plain block.

Embodiment sees also shown in Figure 1, the utility model comprise n can produce λ 1, λ 2, λ 3 ... λ n, the laser instrument of n kind different wave length laser or laser aligner 101,102,103 ... 10n, can make different wavelength of laser transmission and reflection with the serial wavelength-division multiplex diaphragm 121,122,123 that swashs combiner ... 12n, have certain thickness serial optical parallel plain block 111,112,113 ... 11n.

When concrete the use, with laser instrument or laser aligner 101,102,103 ... 10n press the direction of almost parallel fixing after, regulate successively wavelength-division multiplex diaphragm 121,122,123 ... light direction was parallel to each other when 12n was adjusted to output with n road different wavelength of laser, and spot center is overlapping as far as possible or approaching, in light path, insert again optical parallel plain block 111,112,113 ... 11n makes the beam center line produce translation, make the central lines of all light beams, thus realize different wavelength of laser overlapping close restraint into a branch of.

See also shown in Figure 2 again, the laser λ n that the utility model also can make laser instrument or laser aligner 10n send is vertical with the laser λ n-1 that laser instrument or laser aligner 10 (n-1) send, directly carrying out light beam by wavelength-division multiplex diaphragm 12 (n-1) closes bundle for it, can save 1 group of wavelength-division multiplex diaphragm and optical parallel plain film like this, insert optical parallel plain block 11 (n-1) in the light path of the laser λ n-1 that laser instrument or laser aligner 10 (n-1) send and make the beam center line produce translation.

As shown in Figure 3, one group of wavelength-division multiplex diaphragm 121 of the present utility model and optical parallel plain block 111 adopt a pair of concavo-convex globe joint 131,132 carry out continuously every or the bonding or the welding in less gap fixing.
