下面將結合附圖，對本技術方案實施例提供之鏡片結 ❹構及鏡片結構陣列及鏡片結構之製造方法作進一步之詳二 說明。 、 請參閱圖1，本技術方案第一實施例提供之鏡片結構 100包括一體成型之第一鏡片110與第一支撐部12〇。 第一鏡片110呈圓形，第一鏡片110具有第一光學面 111、與第一光學面111相對之第二光學面112及連接於第 一光學面111與第二光學面112之間之第一侧面113。本實 施例中，第一鏡片110為雙凸透鏡，第一光學面U1之中 心具有圓形凸起，圓形凸起具有球形曲面之表面。第二光 8 201020090 學面112之中心亦具有圓形凸起，圓形凸起亦具有球形曲 面之表面。當然，第一鏡片110亦可為其他形狀之鏡片， 如雙凹透鏡、凸透鏡等。 第一支撐部120亦呈圓形，第一支撐部120具有第一 表面121、與第一表面121相對之第二表面122及連接於第 一表面121與第二表面122之間之第一侧壁123。該第一表 面121為平面，第二表面122與第一鏡片110之第一光學 面111配合接觸。即，於第二表面112之中心具有與第一 ®鏡片110之第一光學面111形成之圓形凸起相配合之凹 陷，從而使得第一鏡片110之第一光學面111可與第二表 面122緊密接觸。 第一鏡片110之中心轴線與第一支撐部120之中心軸 線重合，第一鏡片110之直徑與第一支撐部120之直徑相 等，從而，第一鏡片110之第一側面113與第一支撐部120 之第一側壁123相互對齊。 φ 第一鏡片110與第一支撐部120均可由透明且具有高 透光率與低吸收率之熱塑性材料或熱固性材料製成。並 且，第一鏡片110之材料之折射率不同於第一支撐部120 之材料之折射率。第一鏡片110採用具有較高之折射率材 料製成時，則第一支撐部120採用具有較低折射率之材料 製成。或者，第一鏡片110採用具有較低之折射率材料製 成時，則第一支撐部120採用具有較高折射率之材料製成。 較高折射率之範圍應介於1.55至1.60之間，較低折射率之 範圍應介於1.45至1.49之間。具有較低折射率之材料可為 201020090 聚甲基丙烯酸曱酯（PMMA)等，具有較高折射率之材料 可為聚碳酸酯（PC)等。由於第一鏡片110之材料與第一 支撐部120之材料之折射率不同，當光從第一鏡片110至 第一支撐部120時，方向發生改變，從而實現鏡片結構100 之光學性能。 請參閱圖2,本技術方案第二實施例提供之鏡片結構 200，其與第一實施例提供之鏡片結構10大致相同，不同 之處在於：鏡片結構200除包括第一鏡片210與第一支撐 ®部220之外，還進一步包括第二支撐部230。

光學面351與第二支撐部340之第四表面342緊密配合接 觸。即，第三光學面351之圓形凸起恰可收容於第二支撐 部340之第四表面342之圓形凹陷中。第四光學面352之 11 201020090 中心亦具有圓形凸起，圓形凸起亦具有球形曲面之表面。 當然，第二鏡片350亦可為其他形狀之鏡片，如雙凹透鏡、 凸透鏡等。 第三支撐部360亦為圓形，第三支撐部360具有相對

亦可不設置濾光片310，而使承載面11與第一端面201之 間距與待成型之第一支撐部320之厚度相等，從而使承載 面11與套筒20之内壁22圍合形成一成型腔。 其次，將熔融之第一支撐部材料填充於外表面314與 套筒20之内壁22圍合形成之成型腔内，利用第一模具30 壓印成型第一支撐部320。第一模具30由透光材料製成。 第一模具30具有第一成型面31，於第一成型面31之形狀 201020090 ' 與第-支樓部320之第二表面322之形狀相對應。於第一 模具3〇上設置有與濾光片310上之第-對位標記313相對 應之第二對位標記34。先將第一模具30放置於套筒2〇之 第Γ端面2〇1上方’並使得第一模具之第二對位標記34 與渡光片310上之第—對位標記313相對。再對第一模具 30施加垂直於承載面u方向之壓力，多餘之液態或溶融態 之成型材料從第一模具3〇第一成型面31與第-端面2〇1 ❹之間流出，直至第一成型面31與第一端面2〇1接觸。 再次，將第一支撐部32〇之支撐部材料固化成型。支 撐部材料處於液態或熔融態，可採用降溫或紫外光照射之 方式使支撐部材料固化。本實施例中，採用紫外光照射之 方式使得支撐部材料固化，以形成第一支禮部32〇。由於第 一模具30由透光材料製成，因此，紫外光可藉由第一模具 30並照射固化第一模具3〇與濾光片31〇之間之成型材料，

INSTRUCTIONS: FIELD OF THE INVENTION The present invention relates to the field of lens fabrication, and more particularly to a method for fabricating a lens structure by continuous imprinting and an array of lens structures and lens structures. [Prior Art] An optical lens having a wafer size is embossed on both sides of a light-transmitting substrate to be embossed into a type-type optical portion (see The Novel Fabrication Method and Optimum Tooling Design Used for Microlens Arrays) Proceedings of the 1st IEEE International Conference on Nano/Micro Engineered and Molecular Systems ; January 18-21, 2006, Zhuhai, China).

The combined lens structure is prone to eccentricity, that is, the optical axes of the lenses are not in line, affecting the optical properties of the lens structure. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a method for manufacturing a lens structure. By adopting the method, the lens structure can be continuously imprinted, thereby avoiding the problem of eccentricity when the individual lenses are assembled into a lens structure in 201020090. a first lens and a first branch, and a first optical surface and a second optical surface, opposite to the first surface and the second surface, the first surface and the first surface The optical surface is mated to contact, and the first surface is made of a flat material.

The method for fabricating the lens structure comprises the steps of: providing the carrying platform with a bearing surface, The bearing surface is a flat surface; the melted first port 7 201020100 is formed on the bearing surface to imprint the first support portion array Forming a first array of support portions, the first set of floor portions having a first array support surface in contact with the load bearing surface and a second array support surface opposite the first array support surface '. forming the melted first lens array material Imprinting the first lens array material to form a first lens array on the first support surface, such that the first lens array has a first array optical surface in mating contact with the second array support surface of the first support array and The first barrier optical surface is opposite to the second array optical surface; (4) the lens structure array 'to obtain a plurality of lens extraction structures. Compared with the prior art 'the lens structure manufacturing method, the support portion and the lens which are sequentially stacked and sequentially stacked can be formed In this way, the optical axis of each optical component generated during the process of fabricating the lens structure is prevented from being shifted. [Embodiment] The lens structure, lens structure array and lens structure provided by the embodiments of the present technical solution will be described below with reference to the accompanying drawings. The manufacturing method is further described in detail. Referring to FIG. 1 , the lens structure 100 provided by the first embodiment of the present technical solution includes one body. The first lens 110 is shaped like a first support portion 12. The first lens 110 has a circular shape, and the first lens 110 has a first optical surface 111, a second optical surface 112 opposite to the first optical surface 111, and a second optical surface 112. The first side surface 113 between the optical surface 111 and the second optical surface 112. In the embodiment, the first lens 110 is a lenticular lens, and the center of the first optical surface U1 has a circular protrusion, and the circular protrusion has a spherical shape. The surface of the curved surface. The second light 8 201020090 The center of the surface 112 also has a circular protrusion, and the circular protrusion also has a surface of a spherical curved surface. Of course, the first lens 110 can also be a lens of other shapes, such as a biconcave lens, The first support portion 120 also has a circular shape, and the first support portion 120 has a first surface 121, a second surface 122 opposite to the first surface 121, and a connection between the first surface 121 and the second surface 122. The first side wall 123. The first surface 121 is a flat surface, and the second surface 122 is mated with the first optical surface 111 of the first lens 110. That is, the center of the second surface 112 has a recess corresponding to the circular protrusion formed by the first optical surface 111 of the first lens 110, so that the first optical surface 111 of the first lens 110 can be combined with the second surface. 122 close contact. The central axis of the first lens 110 coincides with the central axis of the first support portion 120, and the diameter of the first lens 110 is equal to the diameter of the first support portion 120, so that the first side 113 of the first lens 110 and the first support The first side walls 123 of the portion 120 are aligned with each other. φ The first lens 110 and the first support portion 120 may each be made of a thermoplastic material or a thermosetting material which is transparent and has high light transmittance and low absorption rate. Moreover, the refractive index of the material of the first lens 110 is different from the refractive index of the material of the first support portion 120. When the first lens 110 is made of a material having a higher refractive index, the first support portion 120 is made of a material having a lower refractive index. Alternatively, when the first lens 110 is made of a material having a lower refractive index, the first support portion 120 is made of a material having a higher refractive index. The higher refractive index should range from 1.55 to 1.60 and the lower refractive index should range from 1.45 to 1.49. The material having a lower refractive index may be 201020090 poly(methacrylic acid methacrylate) (PMMA) or the like, and the material having a higher refractive index may be polycarbonate (PC) or the like.
