Description
本發明涉及一種鏡片鍍膜治具。 The invention relates to a lens coating jig.
隨著光學產品之發展，光學鏡片之應用範圍越來越廣。相應地，業界採用各種方法來製造光學鏡片以適應市場對不同規格光學鏡片之需求(請參閱“Fabrication of Diffractive Optical Lens for Beam splitting Using LIGA Process”,Jauh Jung Yang；Mechatronics and Automation,Proceedings of the 2006 IEEE International Conference on，pp.1242-1247,2006.06)。同時，為降低成本及提高效率，進行批量生產以滿足對光學鏡片之需求。通常來說，製造出之光學鏡片需經過後續處理以獲得適於應用之良好性能。 With the development of optical products, the application range of optical lenses is becoming wider and wider. Accordingly, the industry uses a variety of methods to fabricate optical lenses to accommodate the market demand for different sizes of optical lenses (see "Fabrication of Diffractive Optical Lens for Beam splitting Using LIGA Process", Jauh Jung Yang; Mechatronics and Automation, Proceedings of the 2006 IEEE International Conference on, pp. 1242-1247, 2006.06). At the same time, in order to reduce costs and improve efficiency, mass production is carried out to meet the demand for optical lenses. Generally, the manufactured optical lens is subjected to subsequent processing to obtain good performance suitable for the application.
鍍膜工序為後續處理中之重要步驟之一。鍍膜係指以物理或化學方法於光學元件表面鍍上單層或多層薄膜，利用入射、反射及透射光線於薄膜介面產生之干涉作用實現聚焦、準直、濾光、反射及折射等效果。光學元件之鍍膜製程為：首先，將光學元件安裝於鍍膜治具上，鍍膜治具設置於一容器中；其次，密閉容器，對容器抽真空；然後，以蒸鍍或濺鍍等 方法於光學元件需要鍍膜之部位進行鍍膜；最後，將經過鍍膜之光學元件從鍍膜治具上拆卸下來。由於先前之鏡片尺寸越來越小，於鍍膜過程中，夾持鏡片之治具將會對鏡片產生遮蔽效應，導致鏡片邊緣出現反射或異色等現象，從而影響鏡片鍍膜之品質。 The coating process is one of the important steps in the subsequent processing. Coating refers to the physical or chemical method of plating a single layer or a multilayer film on the surface of an optical element, and utilizing the interference of incident, reflected and transmitted light on the film interface to achieve focusing, collimation, filtering, reflection and refraction. The coating process of the optical component is: first, the optical component is mounted on the coating fixture, the coating fixture is disposed in a container; secondly, the container is sealed, and the container is vacuumed; then, by evaporation or sputtering, etc. The method is applied to the portion where the optical component needs to be coated; finally, the coated optical component is removed from the coating fixture. As the size of the previous lens is getting smaller and smaller, during the coating process, the fixture holding the lens will have a shadowing effect on the lens, causing reflection or abnormal color on the edge of the lens, thereby affecting the quality of the lens coating.
有鑒於此，有必要提供一種防止鏡片鍍膜產生遮蔽效應之治具。 In view of the above, it is necessary to provide a jig that prevents the lens coating from producing a shadowing effect.

請參見圖2，本發明實施例提供之鏡片鍍膜治具100所承載之鏡片20之結構示意圖。該鏡片20包括一個中心光學部201與一個圍繞該中心光學部201之承載部202。 2 is a schematic structural view of a lens 20 carried by a lens coating jig 100 according to an embodiment of the present invention. The lens 20 includes a central optic 201 and a carrier 202 surrounding the central optic 201.
該承載部202包括一個承載第一表面2021以及一個與該承載第一表面2021相對之承載第二表面2022，於該承載部202之承載第一表面2021與該承載第二表面2022上之遠離該中心光學部201之邊緣處分別形成複數個向該鏡片20內延伸之缺口203，於本實施例中，該複數個缺口203沿該鏡片20之圓周方向對稱分佈，且形成於該承載部202之承載第一表面2021之複數個缺口203與形成於該承載第二表面2022上之複數個缺口203分別相對設置。 The carrying portion 202 includes a carrying first surface 2021 and a carrying second surface 2022 opposite to the carrying first surface 2021, and the carrying first surface 2021 of the carrying portion 202 and the carrying second surface 2022 are away from the A plurality of notches 203 extending into the lens 20 are formed at the edges of the central optical portion 201.

請參見圖3，本發明實施例提供之鏡片鍍膜治具100之使用狀態示意圖。該基體11之複數個第一凸起112與該蓋體12之複數個第二凸起122分別與該鏡片20之複數個缺口203相配合用以夾持上述鏡片20。且該第一凸起112之高度H3以及該第二凸起122之高度H1分別等於該複數個缺口203之高度H2，因此，該鏡片20之承載部202之承載第一表面2021與該蓋體12之第四表面1202於同一個平面上，該鏡片20之承載部202之承載第二表面2022與該基體11之基體第二表面1102於同一個平面上，從而使得該鏡片20之中心光學部201不會被治具所遮蔽，從而有利於鍍膜之順利進行。 Referring to FIG. 3, a schematic diagram of a state of use of the lens coating jig 100 according to an embodiment of the present invention is shown. The plurality of first protrusions 112 of the base 11 and the plurality of second protrusions 122 of the cover body 12 cooperate with the plurality of notches 203 of the lens 20 to clamp the lens 20 . The height H3 of the first protrusion 112 and the height H1 of the second protrusion 122 are respectively equal to the height H2 of the plurality of notches 203. Therefore, the bearing surface 202 of the lens 20 carries the first surface 2021 and the cover. The fourth surface 1202 of the lens 12 is on the same plane, and the second surface 2022 of the bearing portion 202 of the lens 20 is on the same plane as the second surface 1102 of the base 11 of the substrate 11, so that the central optical portion of the lens 20 is 201 will not be covered by the fixture, which will facilitate the smooth progress of the coating.
可理解的是，該複數個第一凸起112、該複數個第二凸起122以及該複數個缺口203亦可沿圓周方向不對稱分佈。該第一凸起112之高度H3以及該第二凸起122之高度H1亦可分別小於該複數個缺口203之高度H2。因此，於使用鏡片鍍膜治具100時，該鏡片20之承載部202之承載第一表面2021高出該蓋體12之第四表面1202，該鏡片20之承載部202之承載第二表面2022高出該基體11之基體第二表面1102，從而使該鏡片20之中心光學部201不會被鍍膜治具100所遮蔽。 It can be understood that the plurality of first protrusions 112, the plurality of second protrusions 122, and the plurality of notches 203 can also be asymmetrically distributed in the circumferential direction. The height H3 of the first protrusions 112 and the height H1 of the second protrusions 122 may also be smaller than the height H2 of the plurality of notches 203, respectively. Therefore, when the lens coating jig 100 is used, the bearing carrying portion 202 of the lens 20 carries the first surface 2021 higher than the fourth surface 1202 of the cover 12, and the carrying portion 202 of the lens 20 carries the second surface 2022. The second surface 1102 of the base of the base 11 is removed such that the central optical portion 201 of the lens 20 is not obscured by the coating fixture 100.
綜上所述，本發明確已符合發明專利之要件，遂依法提出專利申請。惟，以上所述者僅為本發明之較佳實施方式，自不能以此限制本案之申請專利範圍。舉凡熟悉本案技藝之人士援依本發明之精神所作之等效修飾或變化，皆應涵蓋於以下申請專利範圍內。 In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law.
