Description
Technical Field
The utility model relates to an optical element technical field specifically says, relates to a novel glued glass lens of high-end single anti-lens.
Background
The main raw material of the glass lens is optical glass which has excellent optical property, good light transmittance and mechanical and chemical properties, constant refractive index and stable physical and chemical properties. In the design and manufacture of high-end single lens reflex, two or more glass lenses are often cemented together in order to meet the requirements of transmittance improvement, chromatic aberration elimination and the like. Traditional glued glass lens, its bore of lens that carries out the veneer is unanimous, and at the veneer in-process, glue is diffused and is overflowed to the edge by the center of lens veneer, through the fixed back of UV light irradiation, glue takes place the chemical reaction solidification behind the ultraviolet ray, and the glue after the solidification will be remained to the lens periphery, produces the influence to follow-up manufacturing procedure such as the japanning of lens to the phenomenon of white point bright line appears. Moreover, even if the residual glue is removed by a pencil sharpener processing mode, the problem of lens scratch and the like is still easily generated in the residual glue removing process, the appearance of the lens is not attractive, and the residual glue particles are more.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
the utility model provides a novel glued glass lens of high-end single anti-lens, is including the first lens base member, solidification cementing layer and the second lens base member that set gradually, first lens base member is equipped with the veneer convex surface towards the second lens base member, the second lens base member is equipped with the veneer concave surface towards the first lens base member, first lens base member and second lens base member use its relative veneer convex surface and veneer concave surface to be a lens body through solidifying cementing layer fixed connection, the edge of veneer concave surface is provided with and solidifies cementing layer assorted inner chamfering.
Further, the first lens substrate is a meniscus lens, and the second lens substrate is a plano-concave lens.
Further, the curvature of the gluing convex surface is consistent with the curvature of the gluing concave surface within the inner chamfer.
Further, the periphery of the lens body is uniformly coated with a dull black paint layer.
Further, the curing glue layer is a UV glue curing glue layer.
Further, the overflow portion of the cured glue layer is received in the inner chamfer of the glue concavity.
Furthermore, the shape of the lens body is a circular structure.
The utility model has the advantages that: the utility model has reasonable structure, low manufacturing cost, high aesthetic degree, good optical performance and strong practicability, and solves the problem of white point and bright line of the existing laminated glass lens; the arrangement of the extinction black paint layer ensures the image quality of the cemented glass lens and avoids the stray light reflection; the arrangement of the inner chamfer of the utility model not only further enhances the adhesive force of the first lens base body and the second lens base body, avoids glue failure, but also ensures the width of overflowing UV glue, and avoids the influence on the coating of the subsequent extinction black paint layer, thereby avoiding the condition of white point bright lines; the utility model discloses a UV glues and veneer, and safety ring protects, and bonding strength is high, and bonding efficiency is high, and transparent, the product does not turn yellow for a long time, does not whiten after the solidification completely, has guaranteed the pleasing to the eye degree and the definition of glued glass lens.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic cross-sectional view of fig. 1.
Fig. 3 is a partially enlarged view of fig. 2.
In the figure: 1. the lens comprises a lens body, 2, a delustering black paint layer, 3, a first lens base body, 4, a curing gluing layer, 5, a second lens base body, 6, a gluing convex surface, 7, a gluing concave surface, 8 and an inner chamfer.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-3, a novel cemented glass lens of high-end single lens reflex, including the first lens base member 3 that sets gradually, solidify veneer 4 and second lens base member 5, first lens base member 3 is meniscus lens, second lens base member 5 is plano-concave lens, first lens base member 3 is equipped with the veneer convex surface 6 towards second lens base member 5, second lens base member 5 is equipped with the veneer concave surface 7 towards first lens base member 3, first lens base member 3 and second lens base member 5 use its relative veneer convex surface 6 and veneer concave surface 7 to be a lens body 1 that is circular structure through solidifying veneer 4 fixed connection. The curing glue layer 4 is formed by UV glue curing, UV glue is dispensed through a dispensing valve of a dispenser (the discharge amount of the glue is stabilized within 3% precision at the moment), then the glue is cured through UV irradiation, the curing time is 24 hours, the glue is baked at high temperature for 3 hours after the curing is finished, the condition that the glue cannot be wiped by using a solvent after the UV glue is cured is ensured, the thickness of the curing glue layer 4 can be set as small as possible, and limitation is not made on the thickness.
The edge of veneer concave surface 7 is provided with and solidifies 4 assorted internal chamfer 8 of veneer concave surface, solidifies the partial interior chamfer 8 that holds in veneer concave surface 7 that overflows of veneer concave surface 4, has both further strengthened the adhesive force of first lens base member 3 and second lens base member 5, avoids splitting glue, has guaranteed again to spill over the width that UV glued glue, has avoided producing the influence to the coating of follow-up extinction black lacquer layer 2 to the condition of white point bright line that leads to. The curvature of the gluing convexity 6 coincides with the curvature of the gluing concavity 7 inside the inner chamfer 8.
