Abstract
The utility model discloses the optical lens that a kind of focal length is 50mm, including the first eyeglass, the second eyeglass, third eyeglass, the 4th eyeglass and the image planes being from left to right arranged in order, the center of each eyeglass and image planes is on the same line, first eyeglass, the second eyeglass, third eyeglass and the 4th eyeglass center thickness be respectively 6.73mm, 4.52mm, 7.16mm and 6.45mm, and its focal length is 50mm.By each optical mirror slip, pass through convergence to ambient and peptizaiton so that light finally can be uniformly applied in image planes, pixel is allow to reach 2,000,000, thus, it is possible to which the optical lens that the focal length is 50mm is applied to detection device or is taken pictures on camera, applicability is improved.
Description
Technical field
The utility model belongs to a kind of light path, more particularly, to the optical lens that a kind of focal length is 50mm.
Background technology
With the development of science and technology, requirement of the people to various products is gradually diversified.In every detection device and phase
There is the light path for using different pixels requirement in machine, but the light path in detection device cannot lead to mostly with magazine light path
With increasing the production difficulty of optical mirror slip.
Utility model content
The purpose of this utility model is to provide the optical lens that a kind of focal length is 50mm, in capable of solving the above problems
It is at least one.
One side according to the present utility model provides a kind of optical lens that focal length is 50mm, including from left to right
The center of the first eyeglass, the second eyeglass, third eyeglass, the 4th eyeglass and the image planes being arranged in order, each eyeglass and image planes is same
On straight line, the first eyeglass, the second eyeglass, third eyeglass and the 4th eyeglass center thickness be respectively 6.73mm, 4.52mm,
7.16mm and 6.45mm, the distance between the first eyeglass, the second eyeglass, third eyeglass and the 4th eyeglass adjacent mirror are followed successively by
0.1mm, 1.58mm and 14.92mm, the first eyeglass are convex lens, the radius of left and right sides minute surface be respectively 24.63mm and
The left and right sides minute surface of 327.6mm, the second eyeglass are raised to the left, and radius is respectively 20.81mm and 37.11mm, third eyeglass
Minute surface for concavees lens, the left and right sides is respectively 605.65mm and 12.35mm, and the left and right sides minute surface of the 4th eyeglass is to the left
Protrusion, radius are respectively 23.94mm and 75.6mm.
The utility model has the beneficial effects that：By each optical mirror slip, by convergence to ambient and peptizaiton,
So that light finally can be uniformly applied in image planes so that pixel can reach 2,000,000, thus, it is possible to be by the focal length
The optical lens of 50mm applies to detection device or takes pictures on camera, improves applicability.
In some embodiments, focal length is the optical lens of 50mm, focal length 50mm.Adjustment is facilitated to detect as a result,
With the clarity requirement in electrophotographic process.
In some embodiments, the both ends of minute surface and the second lens contacts on the left of third eyeglass.Thus, it is possible to ensure
The light of two eyeglasses convergence, can act on third eyeglass.
Description of the drawings
Fig. 1 is the light path principle schematic diagram that the focal length of the utility model is the optical lens of 50mm.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig.1：Focal length is the optical lens of 50mm, including the first eyeglass 1, the second eyeglass being from left to right arranged in order
2, the center of third eyeglass 3, the 4th eyeglass 4 and image planes 5, each eyeglass and image planes on the same line, the first eyeglass 1, the second mirror
The center thickness of piece 2, third eyeglass 3 and the 4th eyeglass 4 is respectively 6.73mm, 4.52mm, 7.16mm and 6.45mm, the first eyeglass
1, the distance between the second eyeglass 2,4 adjacent mirror of third eyeglass 3 and the 4th eyeglass be followed successively by 0.1mm, 1.58mm and
14.92mm, the first eyeglass 1 are convex lens, and the radius of left and right sides minute surface is respectively 24.63mm and 327.6mm, the second eyeglass 2
Left and right sides minute surface it is raised to the left, radius is respectively 20.81mm and 37.11mm, and third eyeglass 3 is concavees lens, left and right two
The minute surface of side is respectively 605.65mm and 12.35mm, and the left and right sides minute surface of the 4th eyeglass 4 is raised to the left, and radius is respectively
23.94mm and 75.6mm.
Wherein, the radius of each minute surface mentioned above refer to the single minute surface of eyeglass vertical optical axis direction size one
Half.
The first eyeglass 1, the second eyeglass 2 and third eyeglass 3 gradually converge ambient as a result,；Then, the 4th mirror
Piece 4 further converges light.To so that the focal length can reach 2,000,000 pixels for the optical lens of 50mm to be wanted
It asks, meets photograph or relevant device detection uses.As shown in Figure 1, dotted line upward arrow direction is illustrated for light direction of transfer in figure
Figure.
Focal length is the optical lens of 50mm, focal length 50mm.Facilitate as a result, and light is adjusted in use
Section, to reach the requirement of light path light.
The both ends of 3 left side minute surface of third eyeglass are contacted with the second eyeglass 2.Thus, it is possible to so that the light of the second eyeglass 2 convergence
Line can act on third eyeglass 3, further be converged.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field
For personnel, without departing from the concept of the present invention, various modifications and improvements can be made, these all belong to
