Similarly, if beam splitter 4(5) be meant beam splitter 5, then light beam 24 and 28 by the last par 13a(of patrix 11a with reference to Fig. 1) reflection, and light beam 26 by the following par 13b(of counterdie 11b with reference to Fig. 1) reflect.
Below, the method for the core shift of revising mould 1 by the optic element forming device 100 with above structure (below, be called transfer core with this action) is described.
At first, penetrate collimated beam, on the surface of photodetector 6, form luminous point S1(with reference to Fig. 2 from light source 2), and use beam splitter 5 on the surface of photodetector 6, to form luminous point S2(with reference to Fig. 2).Then, adjust the angle of inclination of patrix 11a and/or counterdie 11b, so that the formation position consistency of the formation position of luminous point S1 and luminous point S2.When these position consistency, among the patrix 11a make by the forming composition moulding time required (being provided with the face of forming part 12a) and counterdie 11b in make by the forming composition moulding time required (being provided with the face of the 12b of compacted under portion) all become appropriate angle of inclination, and be parallel to each other.Like this, can transfer core to the inclination core shift by patrix 11a in the correction mould 1 and the parallelism of counterdie 11b.
Then, adjust the position on directions X and Y direction beam splitter 4 or patrix 11a in advance, so that be incident upon last summit 12ac in the combination of a certain composing type portion from the light beam of beam splitter 4 guiding patrix 11a (that is, shown in Figure 2 light beam 24).Afterwards, make light source 2 penetrate collimated beam, and on the surface of photodetector 6, form luminous point S1(with reference to Fig. 2), and use beam splitter 4 on the surface of photodetector 6, to form luminous point S2(with reference to Fig. 2).Then, adjust the position on directions X and Y direction of counterdie 11b, so that the formation position consistency of the formation position of luminous point S1 and luminous point S2.When these position consistency, the last summit 12ac in the combination of a described composing type portion is located on the same straight line of Z direction (with the perpendicular direction in described appropriate angle of inclination) extension each other with following summit 12bc.So just, can reach parallel core shift between the 12b of compacted under portion with its subtend (two surfaces of optical element separately in the heart position offset) to the last forming part 12a that a composing type portion described in the mould 1 combination be correlated with and transfer core.
Next, accent core same as described above, parallel core shift is carried out in other at least one group forming part combinations different with above-mentioned forming part combination.At this moment,, beam splitter 4 is moved for above-mentioned other the forming part combination of beam direction, also can reset other beam splitters 4(make up at each forming part of each mould of subtend configuration the forming part reflecting mechanism is set).Consequently, can make up the accent core that carries out parallel core shift with regard at least two composing type portions, therefore can be on the cycle direction of the optical axis of each optical element (with the cycle direction on vertical of the optical axis), promptly, can transfer core to counterdie 11b with respect to the cycle degree of patrix 11a along the face that is constituted by directions X and Y direction.
In addition, beam splitter 4 and 5 need not to be provided with separately separately, also can the be shared same beam splitter that moves of accent core operation that can corresponding mould 1.
In addition, about in order to adjusting patrix 11a and the angle of inclination of counterdie 11b and/or the technical pattern of position, can be by with patrix 11a and counterdie 11b is installed on the movable pedestal respectively and this pedestal is moved realizes.Such structure can utilize known common technology easily to realize, therefore omits its detailed description at this.
