The invention further proposes a method of forming an optical raft in a third aspect. First, a template having a first cylindrical groove and a second cylindrical groove is provided. Secondly, the first columnar groove and the second columnar groove are respectively filled with the first polymerizable material, but the first polymerizable material is not connected in series with the first columnar groove and the second columnar groove. . Then, a prepolymerization step is performed such that the first polymerizable material in the first columnar groove and the second columnar groove becomes a prepolymerized material. Continuing, the second polymerizable material is again coated such that the second polymerizable material simultaneously contacts the prepolymerized material in the first cylindrical groove and the second cylindrical groove.

The present invention first provides a method of forming an optical enthalpy. The optical cymbal formed by this method can also be used as a transparent rib structure for integrated optical tampering.

Figures 1 through 6 illustrate an exemplary flow of the method of the present invention. Referring to Figure 1, first, an optical raft is made using the template 105. The template 105 used has a single piece of plane 106 and a plurality of columnar grooves in the plane, such as a first cylindrical groove 110 and a second cylindrical groove 120. The first cylindrical recess 110 and the second cylindrical recess 120 extend parallel to each other on the plane 106. FIG. 1 is a schematic view of a template 105 of the present invention. The shape of the template 105 may be circular, elliptical or rectangular, and the material used for the template 105 may be a plastic-like material. The width of the columnar grooves may be the same or different, for example, the width of the columnar grooves may be between 0.03 mm and 1.00 mm.

Fig. 1A is a side view showing Fig. 1. Please refer to FIG. 1 and FIG. 1A respectively. Preferably, the same plane 106 of the template 105 can also be arranged with more columnar grooves, such as the third columnar groove 130, the fourth column groove 140 or It is more columnar grooves. The present invention is a non-limiting example of the first columnar groove 110, the second columnar groove 120, the third columnar groove 130, and the fourth columnar groove 140, which are illustrated in the respective figures. . The third columnar groove 130 and the fourth columnar groove 140, as well as the first columnar groove 110 and the second columnar groove 120, extend parallel to each other.

Each cylindrical groove has its own apex angle and depth. For example, the first columnar groove 110 has a first apex angle 111 and a first depth 112, the second columnar groove 120 has a second apex angle 121 and a second depth 122, and the third columnar groove 130 has a third The top corner 131 and the third depth 132 and the fourth columnar recess 140 have a fourth top angle 141 and a fourth depth 142. The top angle and depth of different columnar grooves may be the same or different depending on the requirements of the optical specifications. For example, the apex angle of the columnar groove may range from 20 degrees to 70 degrees, the depth may range from 0.1 mm to 1.0 mm, and the aspect ratio may range from 1:1 to 1:3. FIG. 1A illustrates that the first columnar groove 110, the second columnar groove 120, the third columnar groove 130 and the fourth columnar groove 140 have the same apex angle, and the first columnar groove 110 and the first column The depth of the two columnar grooves 120 is 200 micrometers, and the depths of the third columnar groove 130 and the fourth columnar groove 140 are 400 micrometers.

In other words, the first columnar groove 110 and the second columnar groove 120 can be regarded as having the same optical parameter in the first optical region, and the third columnar groove 130 and the fourth columnar groove 140 are It can be considered to be located in the second optical region adjacent to the first optical region, and thus has different optical parameters. Since the plane 106 of the template 105 can simultaneously accommodate multiple sets of optical regions having different optical parameters, the distance D between the different cylindrical grooves can be the same or different. The distance D between the different columnar grooves may be between 2 mm and 15 mm. For example, a first cylindrical recess 110 and the second cylindrical recess 120 a distance D _1, a second cylindrical recess 120 and the third cylindrical recess distance D 130 between the _two, the third cylindrical recess The distance D ₃ between the 130 and the fourth cylindrical recess 140 may be adjusted to be the same or different as needed. Figure 1A shows D ₁ <D ₂ <D ₃ .

Next, referring to FIG. 2, the respective columnar grooves are independently filled with the polymerizable material 150, for example, respectively in the first columnar groove 110, the second columnar groove 120, and the third column. The shaped recess 130 and the fourth cylindrical recess 140 are filled with the polymerizable material 150 to be injected by a dispenser (not shown). Preferably, since the polymerizable material 150 is filled in the respective columnar grooves independently, the polymerizable material 150 is simply filled into the respective columnar grooves, but the columnar shapes are not The grooves are connected in series, or connected to each other. Figure 2A shows a side view of Figure 2. The polymerizable material 150 is at least filled with the respective columnar grooves. Preferably, the polymerizable material 150 may also fill the respective columnar grooves to form a convex surface. 2A illustrates that the polymerizable material 150 is filled flat in the first columnar groove 110 and the second columnar groove 120, and the polymerizable material 150 fills the third columnar groove 130 and the fourth columnar groove. 140. Note, however, that the polymerizable material 150 is not to overflow the respective columnar grooves such that the polymerizable material 150 connects the columnar grooves together.

The polymerizable material 150 is an organic liquid that can undergo polymerization. The polymerization which can be carried out may be an anionic polymerization reaction, a cationic polymerization reaction, a radical polymerization reaction or a condensation polymerization reaction. The polymerizable material 150 is preferably a liquid so that the polymerizable material 150 can be easily filled completely into the cylindrical grooves without leaving voids. More preferably, the smaller the reduction in volume of the polymerizable material 150 after complete polymerization, the more desirable. The polymerizable material 150 can be an optical plastic and includes a suitable polymerization initiator such as Darocur. The viscosity of the polymerizable material 150 can be between 10 cp and 20000 cp.

Then, referring to FIG. 3, the pre-polymerization step is performed such that the first columnar groove 110, the second columnar groove 120, the third columnar groove 130, and the fourth columnar groove 140 are filled. The polymeric material 150 is polymerized into a prepolymerized material via incomplete polymerization. The prepolymerization step carried out must be an incomplete polymerization reaction, so that the polymerizable material 150 is not completely polymerized into the prepolymerized material 159, so the prepolymerized material 159 is preferably a combination of relatively few repeating units. An oligomer, an oligomer. The incompletely polymerized prepolymerized material 159 is preferably not a solid but a high viscosity liquid having a viscosity higher than that of the original polymerizable material 150. Figure 3A shows a side view of Figure 3.

It is recommended to determine how to carry out the incomplete polymerization of the prepolymerization step depending on the chemical nature of the polymerizable material 150. For example, incomplete polymerization of the prepolymerization step can be carried out by heat or light. For example, if the polymerizable material 150 is subjected to incomplete polymerization of the prepolymerization step by heat, the polymerizable material 150 may be heated to about 150 ̊C over a period of about 3 minutes to 30 minutes. Alternatively, if the polymerizable material 150 is subjected to incomplete polymerization of the prepolymerization step by light, the polymerizable material 150 may be at an energy density of about 1 Joules per square centimeter to 6 Joules per square centimeter, under 365 nm of ultraviolet light. About 2 minutes to 10 minutes. Alternatively, it is also possible to determine the reaction end point of the prepolymerization step by increasing the illuminance, energy or temperature holding time, such as time method and light absorption method. For example, confirm that the shape of the product is no longer changing to confirm the end of the reaction.

Continuing, referring to Fig. 4, the polymerizable material 160 is again injected and pressed in a dispenser (not shown) and coated on the plane 106 of the template 105 such that the second polymerizable material 160 contacts all of the same simultaneously. Prepolymerized material 159 in the cylindrical recess. The thickness of the second polymerizable material 160 after application of the flattening may be between 60 micrometers and 400 micrometers. Figure 4A shows a side view of Figure 4. The polymerizable material 160, like the polymerizable material 150, is also a liquid that can undergo polymerization. The polymerizable material 150 and the polymerizable material 160 may be the same liquid that can undergo polymerization. Alternatively, the polymerizable material 150 and the polymerizable material 160 may be different and may be subjected to the same polymerization conditions. The polymerizable material 160 can be referred to the description of the aforementioned polymerizable material 150.

Next, referring to Fig. 5, the glass substrate 170 as needed is placed over the second polymerizable material 160 which has not yet been polymerized and is still liquid. The glass substrate 170 can be optical glass or industrial glass and can have a thickness between 200 microns and 1300 microns. Fig. 5A is a side view showing Fig. 5. If the glass substrate 170 is not used, proceed to the next step.

Next, referring to Fig. 6, another polymerization reaction is carried out after the incomplete polymerization reaction, which is called a final polymerization step. However, unlike the incomplete polymerization represented by the prepolymerization step, the final polymerization step must be a complete polymerization process. After the final polymerization step, the prepolymerized material 159 and the second polymerizable material 160 are polymerized together, but the prepolymerized material 159 becomes the first final polymeric material 151 and the second polymerizable material 160 becomes the second final polymeric material 161. The third columnar groove 130 has a third final polymeric material 151 therein. At this time, the first final polymeric material 151 and the second final polymeric material 161 together with the glass substrate 170 as occasionally required constitute a transparent rib structure for optical enamel, and the composite optical enthalpy provided by the present invention is obtained. 100. The first final polymeric material 151, the second final polymeric material 161, and optionally the glass substrate 170 are highly penetrating for a predetermined source of light.

Fig. 6A is a side view according to Fig. 6. In a feature of the invention, the prepolymerized material 159 located in each of the columnar grooves is polymerized together with the second polymerizable material 160 to produce a first interface 113 and a second interface 123, respectively. In a feature of the invention, the first interface 113 and the second interface 123 are a material interface rather than an optical property interface. In other words, the first final polymeric material 151 and the second final polymeric material 161 have substantially the same refractive index, that is, the difference in refractive index between the first final polymeric material 151 and the second final polymeric material 161 is negligibly small. Do not count or not observe. Preferably, the first final polymeric material 151 and the second final polymeric material 161 have the same refractive index, so that between the first interface 113 and the second interface 123, there is no optical property, such as refractive index or The difference in the reflective surface is considered as the difference in material properties. Similarly, the first final polymeric material 151 located in the third cylindrical recess 130 and the second final polymeric material 161 together define a third interface 133 after the final polymerization step. The first final polymeric material 151, which is again located in the fourth cylindrical recess 140, and the second final polymeric material 161 together define a fourth interface 143 after the final polymerization step.

That is, the prepolymerized material 159 and the second polymerizable material 160 located in each of the columnar grooves respectively generate a first interface 113, a second interface 123, a third interface 133 and a fourth interface 143 after polymerization. The interface of polymer materials with different polymer properties is separated. Since the initial state of the prepolymerized material 159 and the second polymerizable material 160, such as viscosity, degree of polymerization, chemical property or length of the main chain, may be different before the final polymerization step, it is caused after the respective polymerizations are completely A final polymeric material 151 and a second final polymeric material 161 each have different polymeric properties. In an embodiment of the present invention, the polymer properties separated by the first interface 113, the second interface 123, the third interface 133, and the fourth interface 143 may be polymerization degree, statistical average molecular weight, dispersion, and glass transition temperature. At least one of the melting temperature with the crystal.

Since a polymer, also called a polymer, is usually a mixture of a group of molecular weights or homologue in homologous series, the degree of polymerization of the polymer referred to herein is Polymerization refers to the average degree of polymerization of homologues in a polymer and can be expressed as a statistical average. The statistical average of the molecular weight of the homologue is called the statistical average molecular weight. A number of different methods are currently known which can be used to calculate the statistical average molecular weight of a polymer. For example, end group analysis, boiling point rise method, freezing point drop method, vapor pressure drop method, osmotic pressure method, light scattering method, viscosity method, ultracentrifugation precipitation method, diffusion method, electron microscope method or gel permeation chromatography method, etc. Wait. The statistical average molecular weight obtained may be a number average molecular weight (M _n ), a weight average molecular weight (M _w ), a viscosity average molecular weight (M _η ), or a z-average molecular weight (M _z ). The peak molecular weight (M _p ) of the non-average molecular weight is also applicable as the case requires. Different statistical molecular weights have their own advantages and disadvantages and the applicable molecular weight range, and the statistical average values of the molecular weights obtained by various methods are also different. The foregoing polymer properties, the statistical average molecular weight of the polymer, and the calculation method thereof are the background knowledge of those skilled in the art in carrying out the prepolymerization step and the final polymerization step of the present invention, so that those skilled in the art can decide how to properly The invention is implemented.

As shown in FIG. 7 , after the first final polymeric material 151 , the second final polymeric material 161 and the glass substrate 170 as needed are demolded, the composite optical raft 100 provided by the present invention is obtained. Also used as a transparent rib structure for optical enamel, comprising a substrate 170 (matrix), a substrate 160, a first ridge (also referred to as a first rib) 115, and a second rib as needed. A peak (also referred to as a second angular rib) 125 and a first valley 181. The substrate 171 as needed is highly penetrating for a predetermined light source. The substrate 170 as desired may be a single piece, defining a glass substrate of a different optical area such that the substrate 161 is sandwiched between the substrate 170 and the first valley 181.

The first ridge 115, that is, the first angular rib, has a first apex angle 111 and a first height 112. The first apex angle 111 of the first ridge 115 and the first height 112 define the optical properties of the first ridge 115. For example, the angle of the first apex angle 111 may range between 20 degrees and 50 degrees, the first height 112 may be between 0.1 micrometers and 1.0 micrometers, and the aspect ratio may be between 1:1 and 1:3. between. The first ridge 115 is located on the substrate 160 and extends upwardly from the substrate 160, for example, extending vertically upward. The first ridge 115 and the substrate 160 are each a high molecular polymer, but because of their different polymeric properties, the first ridge 115 and the substrate 160 have a first interface 113.

The second ridge 125, that is, the second angular rib, has a second apex angle 121 and a second height 122. The second apex angle 121 and the second height 122 of the second ridge 125 define the optical properties of the second ridge 125, and FIG. 7 illustrates that the first ridge 115 and the second ridge 125 are located together in the first optics. In area 101. For example, the angle of the second apex angle 121 may range between 20 degrees and 50 degrees, the second height 122 may be between 0.1 micrometers and 1.0 micrometers, and the aspect ratio may be between 1:1 and 1:3. between. The second ridge 125 is located on the substrate 160 and extends upwardly from the substrate 160, for example, extending vertically upward.

The first peak 115 and the second peak 125 are the same high molecular polymer, so the polymerization properties are the same. Although the second ridge 125 and the substrate 160 are each a high molecular polymer, the second ridges 125 and the substrate 160 have a second interface 123 because of their different polymeric properties.

The substrate 160 may have a third peak 135 and a fourth peak 145 as needed. Similarly, the third ridge 135, that is, the third triangular rib, has a third apex angle 131 and a third height 132, and the fourth ridge 145 has a fourth apex angle 141 and a fourth height 142. The third ridge 135 and the substrate 160 are each a high molecular polymer, but because of their different polymeric properties, the third rib 135 and the substrate 160 have a third interface 133. The fourth ridge 145 and the substrate 160 are also each a high molecular polymer, but because of their different polymeric properties, the fourth rib 145 and the substrate 160 also have a fourth interface 143. Figure 7 shows that the third edge 135 and the fourth peak 145 are located in the second optical region 102 different from the first optical region 101 of the first peak 115 and the second peak 125, so although the angle is the same , but its height is different.

The substrate 160 has substantially the same refractive index as each of the ridges, that is, the difference in refractive index between the first final polymeric material 151 of each ridge and the second final polymeric material 161 of the substrate 160 is negligibly small Or not observed. Preferably, the first final polymeric material 151 and the second final polymeric material 161 have the same refractive index, and therefore are not considered to be between the first interface 113, the second interface 123, the third interface 133 and the fourth interface 143. There are optical properties, such as differences in refractive index or reflective surface, but are considered as differences in material properties, so each interface is not considered to be an optical property difference interface, but a material property interface.

Although the polymer material of the substrate 160, the first ridge 115 and the second ridge 125 is a homologue, the first interface 113, the second interface 123, the third interface 133 and the fourth interface 143 are separated by different Polymer properties. That is to say, the polymer material interface has different polymer properties on both sides. In an embodiment of the present invention, the polymer properties separated by the first interface 113, the second interface 123, the third interface 133, and the fourth interface 143 may be polymerization degree, statistical average molecular weight, dispersion, and glass transition temperature. At least one of the melting temperature with the crystal. Please refer to the above for details of polymer properties.

A first trapezoidal first valley 181 is further provided on the substrate and between the first peak 115 and the second peak 125. The size of the first valley 180 is determined by the apex angle of the ridges and the spacing D ₁ and is also one of the optical properties of the integrated optical raft of the present invention. Similarly, there is a trapezoidal second valley 182 between the second peak 125 and the third peak 135. There is a trapezoidal third valley 183 between the third peak 135 and the fourth peak 145. Please note that the second valley 182 is located on the boundary of the first optical region 101 and the second optical region 102, and does not belong to the first optical region 101 nor to the second optical region 102. In the composite optical crucible 100, the spacing, apex angle and height of the ridges need to be continuously tested to find the most suitable size for the optical raft.

Fig. 8 is a top view of a certain ridge in the composite optical disk 100 of the present invention. As can be seen from Fig. 8, the composite optical tweezers produced by the method of the present invention have excellent optical properties of the ribs and no bubbles. Therefore, the transparent rib structure provided by the present invention is a composite optical yoke, and therefore naturally has an advanced value in optical enamel products. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
