Rather, these embodiments are provided so that this disclosure will be thorough and complete. The following directions such as "axial direction", "above", "below", etc. are for more clearly showing the structural positional relationship and are not intended to limit the present invention. In the present invention, the terms "vertical", "horizontal" and "parallel" are defined as: including ± 10% of cases based on the standard definition. For example, vertical generally refers to an angle of 90 degrees relative to a reference line, but in the present invention, vertical refers to a situation within 80 to 100 degrees inclusive.
Referring to fig. 3 to 4, the cemented prism of the present embodiment includes a first optical lens 1, a second optical lens 2, a cementing layer 3 and a plating layer 4.
The first optical lens 1 and the second optical lens 2 in the present embodiment are fixed integrally by the adhesive layer 3. The first optical lens 1 in this embodiment can be made of glass. Similarly, the second optical lens can be made of glass. In some embodiments, the first optical lens 1 and the second optical lens 2 may be made of the same material. For example, the first optical lens 1 and the second optical lens 2 are made of glass. For another example, the first optical lens 1 and the second optical lens 2 are both made of plastic. In some embodiments, the first optical lens 1 and the second optical lens 2 may be made of different materials, for example, one of them is made of glass, and the other is made of plastic. The thickness of the glue layer in this embodiment is between 1-10 um.
The absolute value of the difference between the refractive indexes of the first optical lens 1 and the second optical lens 2 in this embodiment is less than 0.2. Further, the absolute value of the difference between the refractive indexes of the first optical lens 1 and the second optical lens 2 is less than 0.1. When the first optical lens 1 and the second optical lens 2 are made of the same material, the absolute value of the difference between the refractive indexes of the first optical lens 1 and the second optical lens 2 is 0.
The absolute value of the difference between the refractive index of the glue layer 3 and the refractive index of the first optical lens 1 and the refractive index of the second optical lens 2 in this embodiment is less than 0.3. Further, the absolute value of the difference between the refractive index of the glue layer 3 and the refractive index of the first optical lens 1 and the refractive index of the second optical lens 2 is less than 0.2. Furthermore, the absolute value of the difference between the refractive index of the glue layer 3 and the refractive index of the first optical lens 1 and the refractive index of the second optical lens 2 is less than 0.1. When light passes through different interfaces, the closer the refractive index between the two interfaces, the less reflection at the interface and the higher the light transmission. Therefore, by setting the absolute value of the difference between the refractive index of the glue layer 3 and the refractive index of the first optical lens 1 and the second optical lens 2 to be less than 0.3, 0.2, or 0.1, the overall light transmittance can be increased.
The coating 4 in this embodiment can be a coating target with good light transmission, such as SiO2，Al2O3，ZrO2，TiO2The refractive index is controlled between 1.38 and 1.8, so that the optical performance is better, the optical loss is reduced when the first optical lens 1, the second optical lens 2 and the cementing layer 3 are provided with the coating 4, and the light transmittance is improved. In other embodiments, the coating 4 may be opaque, and the coating 4 may reflect all light on the surface on which the coating 4 is disposed.
The plating layer 4 in this embodiment is provided on one or more of the sides of the cemented prism. The coating 4 comprises a first portion 41 covering the lateral part of the glue layer 3. Further, the plating layer 4 may further include a second portion 42 covering at least a portion of one side surface of the first optical lens 1 and a third portion 43 covering at least a portion of one side surface of the second optical lens 2. Further, the second portion 42 completely covers one side of the first optical lens 1, and the third portion 43 completely covers one side of the second optical lens 2.
The upper surface of the first optical lens 1 in this embodiment is provided with an incident surface 11, and the lower surface of the second optical lens 2 is provided with an exit surface 21, and light enters the prism from the incident surface 11 and exits from the exit surface 21. When the side of the glue layer 3 is provided with the plating layer 4, the juncture of the glue layer 3 and the plating layer 4 forms total reflection, so that at least a part of light reaching the juncture of the glue layer 3 and the plating layer 4 is reflected to the second optical lens 2, and light spots are prevented from being formed at the juncture of the glue layer 3 and the plating layer 4.
In the present embodiment, since the occurrence of flare is avoided by the plating layer 4, the area of the incident surface 11 occupies at least 80%, 85%, or 95% or more of the area of the upper surface of the entire first optical lens 1. Further, the area of the incident surface 11 is equal to the area of the upper surface of the first optical lens 1. Thus, the active area of the prism can be increased.
The thickness of the plating layer 4 in this embodiment is greater than 10 nm. The thickness of the plating layer 4 here refers to the thickness of the plating layer 4 with respect to the first optical lens 1 or the second optical lens 2. The thickness of the plating layer 4 is greater than 10nm, which ensures that the plating layer 4 completely covers the glue line (the side of the glue layer 3, such as the recesses 31 or the protrusions 32).
Referring to fig. 3 and 4, in one embodiment, the side surfaces of the first optical lens 1, the second optical member 2 and the glue layer 3 are flush with each other on the same side surface of the optical prism. The plating layer 4 is provided on the side surface.
Referring to fig. 5 and 6, in one embodiment, a concave portion 31 is formed on the same side of the prism by the end of the glue layer 3, the first optical lens 1 and the second optical lens 2. At least a part of the plating layer 4 is embedded in the recess 31 to fill the recess 31. Specifically, the first portion 41 of the plating layer 4 has a protrusion thereon, and the protrusion is embedded in the recess 31 to fill the recess 31. Further, the plating layer 4 is bonded to the end of the glue layer 3. The existence of the concave portion 31 causes a gap to exist between the first optical lens 1 and the second optical lens 2, a blaze line is formed at the concave portion 31 due to reflection, diffraction and scattering of incident light, and the concave layer 31 is filled with the plating layer 4, so that the reflection, diffraction and scattering at the concave portion 31 can be reduced or eliminated, and the blaze line is eliminated. The outer side surface of the plating layer 4 in this embodiment is set to be a flat surface.
Referring to fig. 7, in an embodiment, the end of the gluing part 3 is protruded from the side of the first optical lens 1 and/or the second optical lens 2 to form a protrusion 32 on the same side of the prism. In one embodiment, the protrusion 32 of the glue layer 3 covers a portion of the side surface of the first optical lens 1 and/or a portion of the second optical lens 2. The plating layer 3 covers the protrusion 32 of the adhesive layer 3 and the side surfaces of the first optical lens 1 and the second optical lens 2. The protrusion 32 of the bonding portion 3 protrudes from the side surface of the first optical lens 1 and/or the second optical lens 2, so as to prevent the bonding layer 3 from pre-cooling and shrinking to form the aforementioned recessed portion. In some embodiments, the projections 32 may also be formed in the finished state due to heat and cold. In some embodiments, the thickness of the plating layer 3 at the protrusion 32 is smaller than the thickness of the plating layer 3 at the side of the first optical lens 1 and/or the second optical lens 2, so that the side of the final prism is kept flat. In some embodiments, the thickness of the coating 3 at the protrusion 32 is equal to the thickness of the coating 3 at the side of the first optical lens 1 and/or the second optical lens 2. Referring to fig. 8, the outer side surface of the plating layer 4 in the present embodiment is set to be flat.
In this embodiment, the absolute value of the difference between the refractive indexes of the plating layer 4 and the glue layer 3, and the refractive indexes of the first optical lens 1 and the second optical lens 2 is less than 0.3. Further, the absolute value of the difference between the refractive indexes of the coating 4 and the glue layer 3, and the refractive indexes of the first optical lens 1 and the second optical lens 2 is less than 0.2. Furthermore, the absolute value of the difference between the refractive indexes of the coating 4 and the glue layer 3, and the refractive indexes of the first optical lens 1 and the second optical lens 2 is less than 0.1.
