Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done description further.
According to one embodiment of present invention, a kind of light guide module that is used to regulate light path between casing is provided.Said light guide module comprises two optical medium pieces (for example glass blocks) that material is identical.Each optical medium piece has an axis and two end faces, and one of them end face is a vertical plane, and it is perpendicular to said axis, and another end face is the inclined-plane, and the angle (hereafter is the inclination angle) of it and said vertical plane is θ, and θ is not 0.The inclination angle on the inclined-plane of two optical medium pieces is identical, and the inclined-plane of two optical medium pieces is relative.With reference to figure 4; An optical medium piece 1 fixing coaxially (for example fixing with the mode of bonding) constitutes first assembly 4 on rigid pipe 3; It is (not shown among Fig. 4 that the inwall of this rigid pipe 3 (for example steel pipe) has groove 11; Can be with reference to figure 7), another optical medium piece 2 fixing coaxially (for example fixing with the mode of bonding) is gone up at rigid member 5 (for example steel pipe or bloom) and is constituted second assembly 7, and the outer wall of this rigid member 5 is provided with the guide rail 6 of projection.The form fit of said rigid pipe 3 and rigid member 5; Rigid member 5 embeds in the rigid pipe 3 and the guide rail 6 of said rigid member 5 embeds in the groove 11 of rigid pipe 3; Make the inclined-plane of two optical medium pieces 1,2 relative; Make second assembly 7 to slide with respect to first assembly 4, so just can regulate two optical medium pieces 1, the distance between 2 on axis along axis.Fig. 5 (a) shows first assembly 4 of the light guide module after the assembling and the synoptic diagram that second assembly 7 is in first relative position; Fig. 5 (b) shows first assembly 4 of the light guide module after the assembling and the synoptic diagram that second assembly 7 is in second relative position; Can find out; Second assembly 7 slides with respect to first assembly 4 along axis, can the two be changed to second relative position from first relative position.Said first assembly 4 is provided with securing member 8 (for example nut), is used for after two optical medium pieces 1, distance adjustment between 2 finish first assembly 4 and second assembly 7 is fixing.Said light guide module also comprises tubular bracket 9, and this tubular bracket 9 can be fixed on the casing of laser optical path.First assembly 4 embeds in the said tubular bracket 9, and can rotate around axis with respect to said tubular bracket 9.Said tubular bracket 9 is provided with securing member 10 (for example nut), is used for after first assembly 4 rotates to desired location, the tubular bracket 9 and first assembly 4 being fixed together.
In a preferred embodiment, the xsect of the inwall of the outer wall of rigid pipe 3 and tubular bracket 9 cross section of axis (promptly perpendicular to) shape is circle, so that rotation.Need to prove; Though the xsect of two the optical medium pieces 1,2 shown in Fig. 4 to 7 cross section of axis (promptly perpendicular to) shape is circle; But those skilled in the art's easy to understand; The xsect of two optical medium pieces 1,2 also can be other shape, and the cross section of axis (promptly perpendicular to) shape is circle as long as the xsect of the inwall of the outer wall of rigid pipe 3 and tubular bracket 9, can reach the effect of being convenient to rotate.
In addition, with reference to figure 6, generally speaking, two optical medium pieces 1, distance is not 0 between 2, and have air gap between the two this moment.
Fig. 3 shows the schematic diagram of this embodiment, and the inclination angle of establishing the inclined-plane of two optical medium pieces is θ, and the refractive index of optical medium is n, and the refractive index of air is that 1, two distance between the optical medium piece is L.When light transmission optical medium piece incided the A point, incident angle was θ, and the refraction angle is β, by the refraction law of light nsin θ=sin β was arranged, then β=arcsin (nsin θ).δ=β-θ is arranged simultaneously, and the side-play amount h of light has so:
Promptly
h=L*tanδ=L*tan(β-θ)=L*tan(arcsin(nsinθ)-θ)（1）
That is to say, regulate the size of the distance L between two optical medium pieces, can make the light path h that correspondingly squints.After distance L is confirmed; First assembly and second assembly are fixed; Again the assembly integral body of first assembly and second assembly is rotated around axis CD; Just can quick adjustment because the mismachining tolerance of cabinet shell or mount the skew that the vertical of light path or this bidimensional of level take place error, thereby compensate above-mentioned error.
Find out easily; The present invention is through the adjustment of two dimensions; It is also fixing promptly to adjust two distance L between the optical medium piece, and the assembly after the axis rotational fixation can compensate because the mismachining tolerance of cabinet shell perhaps mounts the skew that the vertical perhaps horizontal direction of light path takes place error again.With respect to prior art, the optical axis before and after light path is corrected between casing of the present invention roughly is on the same straight line, can not cause the interior space of casing idle, helps improving the space availability ratio in the casing; The occupation space of light guide module of the present invention own is less; And the present invention need not use and can carry out the electronic mirror holder that 4 dimensions are regulated, and is with low cost.
At last, the above embodiments only are used for explaining the present invention, and it should not be construed is that protection scope of the present invention is carried out any restriction.And, it will be apparent to those skilled in the art that do not breaking away under the foregoing description spirit and the principle, to various equivalent variation that the foregoing description carried out, modification and in the text not the various improvement of description all within the protection domain of this patent.
