Detailed Description
The invention is further described with reference to the following figures and specific examples.
The invention adopts two or more than two optical materials with different refractive indexes to form two or more than two groups of semi-micro wedge angle sheets with different angle combinations by splicing through optical cement, and can obtain a micro light beam separation angle under the condition of a large-angle wedge angle only by the fact that the refractive indexes of the optical materials are similar; the large-angle wedge angle is convenient to process, and various problems of micro wedge angle processing are avoided; and the micro wedge angle sheet with any angle can be manufactured.
Specifically, the method for manufacturing the composite optical wedge angle piece comprises the following steps: (1) deepening and gluing at least two optical elements together, wherein the optical elements are made of different materials with similar refractive indexes; (2) polishing the light transmitting surface of the optical element combination after the optical cement is deepened to ensure that the light emitting surface is spliced by the different materials; both polished optical elements have a wedge angle with the same inclination.
As shown in fig. 2 and 3, a combination of an optical flat sheet 12 and a wedge angle prism 11 with similar refractive indexes is adopted, and the wedge angle prism 11 has a wedge angle of delta theta; the optical flat sheet 12 is closely overlapped on the inclined plane of the wedge angle prism 11 and deepens the optical cement into a whole; and then the upper end of the optical element combination is horizontally polished into a light-emitting surface parallel to the lower end surface, the light-emitting surface is formed by splicing the two materials, and a delta theta wedge angle is processed on the horizontally polished optical flat sheet. Wherein the refractive index n2 of the optical flat sheet is greater than the refractive index n1 of the wedge-angle prism, and n2-n1 are less than or equal to 0.1, preferably less than 0.02, and the difference between the coefficients of expansion is less than or equal to 5 × 10-6K. When a certain beam separation angle is required, if the refractive index difference of the two optical materials is smaller, the required delta theta wedge angle is larger, so that the processing is easier and the precise control is easier.
In the second method shown in fig. 4 and 5, two optical flat sheets (the first optical flat sheet 21 and the second optical flat sheet 22) with similar refractive indexes are horizontally spliced and deepened to form an optical cement; and then the optical element combination is polished into a combined wedge angle prism, the combination after flat polishing has a delta theta wedge angle, and the inclined surface of the combined wedge angle prism is formed by splicing the two materials. The refractive index n1 of the material of the second optical flat sheet 22 at the lower end of the inclined surface is smaller than the refractive index n2 of the material of the first optical flat sheet 21 at the higher end, and similarly, n2-n1 are less than or equal to 0.1, preferably less than 0.02, and the difference in the expansion coefficients is less than or equal to 5 x 10-6K. When a certain beam separation angle is required, if the refractive index difference of the two optical materials is smaller, the required delta theta wedge angle is larger, so that the processing is easier and the precise control is easier.
For example, in the composite optical wedge plate prepared by the second method, the incident light may have slight grazing reflection light at the optical cement position of the two optical flat plates, so that the optical wedge plate is best processed by using the optical flat plate which is as thin as possible, and the optical path length of the grazing reflection is reduced. However, the excessively thin optical flat sheet increases the difficulty of polishing into a wedge prism, and for this reason, a thickened optical flat sheet 23 is added. As shown in fig. 6, after the two optical flat sheets are horizontally spliced, the combined flat sheet is stacked on the thickened optical flat sheet 23 and the optical cement is deepened into a whole, and then the polishing process is performed on the combination of the two optical flat sheets. In the method, the thickness of the two optical flat sheets can be controlled to be 20-50 microns.
In the third method shown in fig. 7 and 8, two optical flat sheets (optical flat sheet three 31 and optical flat sheet four 32) with similar refractive indexes are adopted to be stacked up and down and deepen the optical cement into a whole; and then the optical element combination is polished into a combined wedge angle prism, the combination after flat polishing has a delta theta wedge angle, and the inclined surface of the combined wedge angle prism is formed by splicing the two materials. The refractive index n1 of the optical flat sheet IV 32 at the lower end of the inclined surface is smaller than the refractive index n2 of the optical flat sheet III 31 at the higher end, and similarly, n2-n1 are less than or equal to 0.1, preferably less than 0.02, and the difference in the expansion coefficients is less than or equal to 5X 10-6K. When a certain beam separation angle is required, if the refractive index difference of the two optical materials is smaller, the required delta theta wedge angle is larger, so that the processing is easier and the precise control is easier.
The composite optical wedge angle sheet manufactured by the method comprises at least two optical wedge angle sheets with different refractive indexes, wherein the light emitting surface of the combined wedge angle sheet is formed by splicing the optical wedge angle sheets with different refractive indexes, and the light beam incident into the combined wedge angle sheet is divided into two beams of light to be emitted; wherein the refractive index of the optical wedge angle piece at the lower end is smaller than that of the optical wedge angle piece at the higher end.
Specifically, as shown in the first structure of fig. 3, the composite optical wedge angle piece manufactured by the first method includes two optical wedge angle pieces, and the two optical wedge angle pieces have bevel edges with the same inclination; the inclined edges of the two optical wedge angle sheets are relatively abutted and deepened to form a group of flat sheets with parallel upper and lower surfaces, the upper surfaces of the flat sheets are spliced by the two optical wedge angle sheets, and the light beams incident into the flat sheets are divided into two beams of light to be emitted. Wherein the refractive index of the optical wedge angle piece at the lower end is smaller than that of the optical wedge angle piece at the higher end.
As shown in fig. 5, the composite optical wedge angle sheet prepared by the second method includes two optical wedge angle sheets, and the two optical wedge angle sheets have bevel edges with the same inclination; the two optical wedge angle sheets are butted along the horizontal direction, optical cement is deepened to form a group of new optical wedge angle prisms, the inclined planes of the formed optical wedge angle prisms are formed by splicing the inclined planes of the two optical wedge angle sheets along the inclined direction, and light beams incident into the optical wedge angle prisms are divided into two light beams to be emitted. Wherein the refractive index of the optical wedge angle piece at the lower end is smaller than that of the optical wedge angle piece at the higher end.
In order to make the two optical wedge angle sheets have the thinnest thickness as possible, a thickened optical flat sheet can be added to the bottom of the second structure, and as shown in fig. 6, the optical wedge angle prisms of the second structure are stacked on the thickened optical flat sheet and deepen the optical cement into a whole.
As shown in fig. 8, the composite optical wedge angle sheet obtained by the method three includes two optical wedge angle sheets, and the two optical wedge angle sheets have bevel edges with the same inclination; the two optical wedge angle sheets are overlapped up and down, optical cement is deepened to form a group of new optical wedge angle prisms, the inclined planes of the formed optical wedge angle prisms are formed by splicing the inclined planes of the two optical wedge angle sheets along the inclined direction, and light beams incident into the optical wedge angle prisms are divided into two light beams to be emitted.
