Description
Technical field
The present invention relates to optical element, particularly relate to a kind of optical mirror slip of injection mo(u)lding.
Background technology
Along with the development of laser lighting technology and 3D body sense interaction technique, demand and the application of near-infrared light source and laser diode are more and more extensive.But LASER Light Source has gaussian beam profile characteristic because of it, it has the features such as the bad and beam shape of beam uniformity is single, and is not suitable for directly being used for illumination application.And existing laser shaping technical scheme common configuration is complicated, realize difficulty.As patent publication No. CN104991347A proposes a kind of laser shaping luminaire based on microlens array, that includes colimated light system, microlens array group and beam-expanding system, complex structure, assembling calibration difficulties.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those skilled in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Figure 1 shows that the structural representation of laser shaping optical element in an embodiment of the present invention.In the present embodiment, comprise the first optical surface and the second optical surface that are arranged in order along light transmition direction, described first optical surface is dispersed with periodically lenticule, for receiving and even diverging incident light, changes beam shape simultaneously; Described second optical surface is polished surface, for increasing the transmitance of diverging light after incidence, to reduce light loss of energy.
Fig. 2 is the first optical surface detail view of laser shaping optical element in an embodiment of the present invention.
The rectangular shape of first optical surface lenticule in embodiments of the present invention.By rectangular-shaped microlens array formula arrangement, can by the process of light beam micronized.Gaussian beam is divided into infinitesimal light beam by lenticule, and every light beams homogeneity is separately much better than Gaussian beam homogeneity.What simultaneously lenticule cyclic array arrangement can improve whole optical element accepts efficiency, reduces light loss of energy.The lenticular length of rectangle is 0.24mm, and wide is 0.18mm, can form the rectangular illuminating area of 4:3, to reach the effect of beam shaping in far field.
First optical surface lenticule is convex surface in embodiments of the present invention.By convex lens, there is converging action, light beam of light source differential can be converged to numerous light pencils, make point light source of single be transformed into multi-point source and irradiate, thus reach certain even light effect.The radius-of-curvature of the R=0.108 of convex microlenses.
First optical surface lenticule adopts aspheric surface in embodiments of the present invention.By adopting aspherical shape, differential light beam can be made to assemble well, the light beam after simultaneously also can making convergence has the larger angle of divergence, to meet the requirement of visual field, field of illumination, thus realizes beam expander effect.The conical section system K=-0.88 of aspherical microlens.
Second optical surface adopts polished surface in embodiments of the present invention, and the surface roughness Ra <0.5 micron of polished surface, reduces and cause optical energy loss because of diffuse reflection.Simultaneously at the second optical surface plated surface antireflective coating, the transmitance of spectrum effectively can be increased.
Fig. 3 A and Fig. 3 B be laser shaping optical element in an embodiment of the present invention shaping before and after design sketch.As can be seen from design sketch, the laser shaping optical element of this specific embodiment 1 has good shaping, expands the effect with even light.
First optical surface described in above-mentioned laser shaping optical element and the second optical surface are by being injected and molded in same optical mirror slip.Described laser shaping optical element have structure simple, shaping can be realized, expand and even light effect.
It should be noted that, design parameter in above-mentioned elaboration is only exemplary, each optical surface parameter such as radius-of-curvature, asphericity coefficient, material etc. are not limited to numerical value shown in above-described embodiment, adopt similar structures and parameter all can reach similar invention technique effect.
Above-mentioned laser shaping optical element adopts the form of the first optical surface microlens array and the second optical surface polished surface, effectively can realize the shaping of laser, expand and even light effect.
Apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping; Meanwhile, for those skilled in the art, according to the thought of the embodiment of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
