Description

  The present invention relates to a composite optical component and a manufacturing method thereof, and more particularly to a composite optical component having a function of changing an optical path such as a lens function formed by resin molding and a manufacturing method thereof.

  Conventionally, an optical element in which an optical function pattern is transferred to the surface of an optical element substrate is known. For example, an optical element is known in which a micro Fresnel lens pattern made of a ring-shaped pattern or the like is formed of a transparent resin on the surface of a transparent lens substrate having a smooth surface. Such a manufacturing method is called a 2P method (abbreviation of photo-polymerization process). Usually, an ultraviolet curable (UV) resin is ejected to a profile as a pattern forming portion formed on the upper surface of the stamper, and a transparent lens substrate having a smooth surface made of glass, synthetic resin, or the like is pressed thereon, The resin is spread on the surface of the stamper so that the resin adheres to the lens substrate, and then the resin is cured by irradiating ultraviolet rays through the lens substrate, and finally the resin is released from the stamper together with the lens substrate.

  However, when the mold is released from the stamper, since the resin is in close contact with the Fresnel lens pattern of the stamper, the resin may be peeled off from the lens substrate. Furthermore, even if a good micro Fresnel lens is manufactured, if it is stored or used in a high temperature or high humidity environment, or if it is used in an environment such as a heat cycle, the heat of the micro Fresnel lens pattern and the lens substrate There is a problem that the micro Fresnel lens pattern is easily peeled off from the lens substrate due to the difference in expansion coefficient.

  Therefore, in Patent Document 1, in an optical element in which an optical functional pattern is transferred to the surface of an optical element substrate, a plurality of concave and convex shapes are provided on the pattern transfer surface of the optical element functional substrate, and the optical functional pattern is adhered to the concave and convex shapes. An optical element characterized by the above is disclosed. Here, if unevenness is provided on the lens substrate, the optical characteristics of the micro Fresnel lens may be adversely affected. In other words, when unevenness is provided on the substrate and a lens function is provided with a material having a different refractive index on the substrate, when the optical path of the light beam is changed through the lens, the change occurs between the uneven portion and the unexposed portion. The situation is different, for example, since the state of light collection is different, there is a problem that light collection is difficult or the design of the lens shape is complicated. Therefore, in Patent Document 1, if the refractive index of the lens substrate and the resin for forming the micro Fresnel lens pattern are the same, the refractive index gap is eliminated, so that inconvenience due to the unevenness can be avoided, and the size of the unevenness is used. It is described that even when the size is sufficiently small with respect to the wavelength of light, the influence due to the unevenness can be ignored, so that the disadvantage due to the unevenness can be avoided.

  In Patent Document 2, in a translucent plate made of a transparent synthetic resin material such as polymethyl methacrylate resin, polycarbonate resin, poly 4 methyl pentene-1, etc., the translucent plate is provided on the light exit surface for emitting light. A light guide plate that is made of a light-transmitting resin different from the conductive plate material and is arranged so that a large number of protrusions having a circular planar shape and an arc-shaped cross-sectional shape are arranged vertically and horizontally at a required interval It is disclosed.

Moreover, the conventional solar power generation system normally generates power by exposing a solar cell panel made of a silicon semiconductor having a power generation function to sunlight. In this case, sunlight is applied to the photoelectric element through a transparent substrate such as glass or through a transparent protective film, but the one provided with a function of condensing light on the transparent substrate or the transparent protective film is provided. It has not been. As described above, an element in which unevenness is provided on a minute optical element substrate and a micro Fresnel lens is formed on the unevenness is known (Patent Document 1), but a synthetic resin is used on a large glass plate. No device has been known that forms a Fresnel lens function and collects sunlight to generate electricity. Here, when forming fine unevenness on the surface of the glass substrate in order to improve the adhesion to the resin, the refractive index of the substrate and the resin material should be matched in order to eliminate the adverse optical effect of the unevenness. Is difficult to select materials and cannot be perfectly matched, and making the unevenness dimension sufficiently smaller than the wavelength of the target light means that a fine molding technique of the order of 100 nm is required, This leads to a significant increase in cost, and is not practical for application as a large-area optical component, and any of the workarounds is not practical.

Suitable for outdoor use.

  In addition, according to the method for producing a composite optical component of the present invention, PDMS used as a raw material for an optical path changing functional layer formed on the surface of a glass substrate has high fluidity before heat treatment, and a thin layer is formed in a wide area. Therefore, it can be easily formed into a desired shape.

  Hereinafter, embodiments of a composite optical component and a method for manufacturing the same according to the present invention will be described. FIG. 1 shows a composite optical component P according to the present invention, in which an optical path changing functional layer 2 made of a transparent synthetic resin having soft elasticity is formed on the surface of a glass substrate 1. Here, “transparent” means having sufficient transparency to light of the target wavelength. In addition, the “soft elastic synthetic resin” has characteristics as a rubber having stretchability and shape restoring property. A typical example of the optical path changing functional layer 2 is a Fresnel lens. And many fine Fresnel lenses may be arranged in the vertical and horizontal directions on the surface of the glass substrate 1 having a large area. Moreover, it is also possible to use a transparent synthetic resin substrate excellent in weather resistance, heat resistance, and cold resistance instead of the glass substrate.

[Selection of synthetic resin materials]
Polydimethylsiloxane (hereinafter abbreviated as “PDMS”) was selected as a transparent synthetic resin that forms a lens shape on a glass substrate. PDMS is highly transparent, has excellent weather resistance, and is rubber elastic. Therefore, it is easy to absorb the difference in thermal dimensional change between glass and PDMS, and also has excellent cold resistance. Suitable for outdoor use. PDMS is the most prevalent silicone and has a wide range of use, from contact lenses and medical instruments to elastomers. Furthermore, since the optical characteristics of PDMS are closely related to the weight average molecular weight and the molecular weight distribution, they can be prepared according to optical requirements such as refractive index.

  As the raw material of PDMS, one-component or two-component liquid silicone can be used. The forming process of the raw material is performed by injecting the raw material into a high-temperature mold in a low-temperature and low-viscosity state and causing a curing reaction in the mold to solidify.

  As a molding method of the synthetic resin material in the present invention, an injection molding method can be adopted, but in the case of PDMS, unlike the thermoplastic synthetic resin injection molding, the raw material material of PDMS that is an injection material has a low viscosity. For example, it is suitable as a synthetic resin for realizing the concept of the present invention in that it is excellent in transferring a fine structure placed on a mold cavity surface in order to form a precise and minute lens or prism. Since the present invention uses a material excellent in fluidity, it is particularly effective when a thin Fresnel lens is formed on a glass substrate.

[Production method]
In the first manufacturing method, as shown in FIG. 2, a PDMS raw material 3 having fluidity is flowed on a glass substrate 1, and a stamper 4 in which, for example, a precise and minute lens or prism mold is formed is pressed onto the glass substrate 1. In this method, after PDMS is thermally cured, the stamper 4 is peeled off to form the optical path changing functional layer 2 on the upper surface of the glass substrate 1. Further, in the second manufacturing method, as shown in FIG. 3, after flowing a PDMS raw material 3 having fluidity on the same stamper 4 as described above, the glass substrate 1 is pressed from above to thermally cure the PDMS, In this method, the stamper 4 is peeled off to form the optical path changing functional layer 2 on the lower surface of the glass substrate 1.

  Here, the surface of the stamper 4 is formed with a pattern forming portion 5 for imparting an optical path changing function, and the unevenness pattern increases the bonding force between the optical path changing function layer 2 and the stamper 4, thereby releasing the mold. Therefore, in order to weaken the bonding force, a mold release agent such as a mold release agent may be applied to the mold surface, or a composite plating for improving the mold release may be applied to the surface. Then, the profile of the pattern forming portion 5 of the stamper 4 is transferred to the surface of the layer made of the PDMS raw material 3 to form the optical path changing functional layer 2. Reference numeral 6 in the figure denotes a Fresnel lens having a profile in which the concave-convex relationship of the pattern forming portion 5 of the stamper 4 is reversed.

  Furthermore, an injection molding method can be adopted as a method suitable for mass production of the present invention. In addition, when performing injection molding, a glass substrate can be set in advance in a mold and so-called insert molding can be performed, but such a method is particularly effective for economical production of the apparatus.

  It is also possible to separately create an optical path changing function sheet corresponding to the optical path changing function layer 2 made of PDMS and then adhere it to the glass substrate 1. Similarly to the above, before bonding the optical path changing function sheet to the glass substrate, the bonding surface of the glass substrate and / or the optical path changing function sheet is subjected to plasma treatment, specifically, oxygen plasma treatment and then bonding. Is preferred. Moreover, before joining the said optical path change function sheet | seat to the said glass substrate, it is also preferable to interpose a thin layer bonding agent in the joint surface of this glass substrate and / or an optical path change function sheet | seat.

[Method to improve adhesion between glass substrate and PDMS]
In the composite optical component P of the present invention, the glass substrate 1 and the optical path changing functional layer 2 made of PDMS must be closely and bonded. In order to bond both materials closely and without any special treatment for normal applications, it is sufficient, but there are cases where higher adhesiveness and stronger adhesiveness are required, and various measures are taken. Is added. At least the adhesive force between the glass substrate 1 and the optical path changing function layer 2 made of PDMS must be higher than the adhesive force between the optical path changing function layer 2 made of PDMS and the stamper 4.

  For example, before the PDMS raw material 3 is brought into close contact with the glass substrate 1, it is effective to perform plasma treatment on the surface of the glass substrate 1 in contact with the PDMS raw material 3. In addition, when an optical path changing function sheet corresponding to the optical path changing function layer 2 made of PDMS is separately prepared and then adhered to the glass substrate 1, the surface of the glass substrate 1 in contact with the PDMS is subjected to plasma treatment or the glass substrate. It is an effective method to perform plasma treatment on the PDMS surface in contact with the surface of 1 or to perform plasma treatment on both surfaces of the glass substrate 1 and PDMS which are to be in contact with each other. Although there are various types of plasma used for the plasma treatment, oxygen plasma is preferable. The plasma treatment is preferably a short time treatment.

  Prior to the bonding, an organic adhesive that does not impair the light transmittance with respect to the wavelength of the target light when using the composite optical component P is applied to the bonding surface of the glass substrate 1 and the optical path changing functional layer 2 made of PDMS. It may be applied to increase the strength of bonding. Moreover, it is also preferable to interpose a thin layer bonding agent between the glass substrate 1 and the optical path changing functional layer 2. Here, the bonding agent is a bonding agent capable of forming siloxane and / or a siloxane derivative by a sol-gel method, and more preferably a tetraethylorthosiloxane (TEOS) and / or a derivative of TEOS.

  Specifically, as a method for improving the bonding strength between the glass substrate 1 and the optical path changing function layer 2 made of PDMS, when the optical path changing function layer 2 is integrally formed on the glass substrate 1, the surface of the glass substrate 1 is In addition, when an optical path changing function sheet made of PDMS formed separately on the glass substrate 1 is bonded, a condensation polymerization compound using a metal alkoxide or a metal salt on the metal alkoxide on the surface of the glass substrate 1 and / or the optical path changing function sheet. And after joining and forming the coating layer (it abbreviates as "coating layer A" hereafter) consisting of the condensation polymerization compound using the mixture which added the metal organic salt thinly, it can join. Or after forming the coating layer A on the surface of the glass substrate 1, PDMS can be injection-molded to produce an integrally molded product of the present invention.

  Similarly, when the optical path changing function layer 2 is integrally formed on the glass substrate 1, when the PDMS optical path changing function sheet separately formed on the glass substrate 1 is bonded to the surface of the glass substrate 1, the glass substrate is used. 1 and / or a polycondensation compound using a mixture of a metal alkoxide and a metal salt and / or a metal organic salt in a polycondensation compound using a metal alkoxide on the surface of the optical path changing function sheet, Bonding is performed after a thin coating layer (hereinafter abbreviated as “coating layer B”) in which the metal colloid is dispersed is formed. Or after forming the coating layer B on the surface of the glass substrate 1, PDMS can be injection-molded to produce the integrally molded product of the present invention. Prior to performing such joining or injection molding, the coating layer A and the coating layer B may be subjected to plasma treatment.

  As a metal constituting the metal salt used when forming the coating layer A and the coating layer B, silicon, zirconium, titanium, boron, aluminum, nickel, tantalum, calcium, magnesium, zinc, or phosphoric acid ester is used. It is preferable to choose. The material of the coating layer A and the coating layer B is at least one of tetraethyl silicate, trimethyl borate, zirconium n-butoxide, titanium isopropoxide, aluminum n-butoxide, zinc chloride, titanium oxide, and ethoxytrimethylsilane. It is preferable that In addition, the process which uses the silane coupling agent which has a some functional group in a molecule | numerator with respect to the surface and / or PDMS surface of the glass substrate 1 can also be performed.
