Embodiment Construction

[0018] Embodiments of the present invention will be described below. The present invention can be applied to any situation as long as the adhesive formed on the substrate is peeled off, but in this embodiment mode, the manufacture figure 1 A method of prism 100 as shown. figure 1 The prism 100 shown in FIG. Various optical films can be used as the optical functional film 9 , for example, a dichroic film that transmits and reflects incident light differently depending on the wavelength can be used.

[0019] Below, according to figure 2 The flow chart of FIG. 1 illustrates the processing flow of this embodiment. for manufacturing figure 1 The Prism 100, initially as image 3 As shown in (a), the flatness and parallelism of the two substrates are obtained mainly by grinding the two surfaces of the flat substrates 10 and 11 composed of glass plates (step S1). Then, among the substrates 10 and 11, the optical functional film 9 is formed on one surface of the substrate 11 (st...

Abstract

The invention provides a peeling method of adhesive capable of peeling an adhesive adhered to a substrate in a short time without exerting an adverse effect to an optical function of an optical element and the environment. Strip-like substrates 3 are adhered to each other by the adhesive 1, an optical functional film 9 is formed on the surface adhered by the adhesive 1 to form the rod-like substrate 6, and a plurality of rod-like substrates 6 are adhered by a temporary adhesive 2 having a thermal expansion coefficient larger than that of the adhesive 1 to constitute a substrate constitutional body 5. In order to selectively peel only the temporary adhesive 2 from the substrate constitutional body 5, the temporary adhesive 2 is peeled by immersing the substrate constitutional body 5 into high temperature water and low temperature water alternatively one or more times.

Description

technical field [0001] The present invention relates to a peeling method for peeling an adhesive bonded to a substrate, a method for manufacturing an optical element using the peeling method, a method for manufacturing a prism, and a prism manufactured using the method for manufacturing a prism. Background technique [0002] Various optical elements are used in constituting an optical system represented by an optical pickup, and these elements are mass-produced, not individually, in order to improve productivity. As an example thereof, Patent Document 1 discloses a method of producing an optical path correction element. In Patent Document 1, many identical sheet glasses are prepared, and a large number of prisms are finally obtained by repeatedly performing lamination and cutting processes on them. Here, an adhesive is used when laminating sheet glass (including members cut after lamination of sheet glass). That is, when laminating sheet glass, each sheet glass is cut|disc...
