Description

TECHNICAL FIELD [0001] The present invention relates to a high magnification optical lens assembly, a method of manufacturing a high magnification optical lens assembly, and an optical apparatus using the high magnification optical lens assembly,

The present invention relates to a high magnification optical lens assembly, a method of manufacturing a high magnification optical lens assembly, and an optical apparatus using the high magnification optical lens assembly, and more particularly to a high magnification optical lens assembly having a deep focal depth and a wide viewing angle, A manufacturing method of the lens assembly, and an optical apparatus using the high magnification optical lens assembly.

Generally, the lens module uses a lens made of a solid material such as glass having a fixed focal length. Such a lens module is required to have a plurality of solid lenses for adjusting the focus and to be able to change the distance between the lenses, which limits the miniaturization of the product and complicates driving for focus adjustment.

Liquid lenses capable of variably controlling the focal distance using electrowetting are being used to complement the disadvantages of such solid lenses. Electro wetting technology is a technique of changing the contact angle of a liquid by applying a voltage between an electrode coated with an insulator and a conductive liquid to control the surface tension of the conductive liquid.

For example, it is possible to arrange a conductive fluid and a non-conductive fluid in a cell having an electrode pattern so as to change the interface position or shape between the two fluids in an electrowetting manner, A variable iris, a variable prism, a variable focus lens, and the like can be implemented by adjusting the channel shape.

However, the conventional optical microscope has a disadvantage that the measurement area becomes narrower and the depth of focus becomes shallower as the measurement is performed at a higher magnification. That is, if a subject having a rough surface such as a fiber is photographed using a conventional high magnification optical lens, it is difficult to obtain a clear image and the shooting range is narrowed.

[

The first electrode unit 1215 is disposed on a part of the lower surface of the first top cover part 1216 and is in contact with the first conductive liquid 1217. The first electrode unit 1215 is preferably a transparent electrode since it must be disposed in a region where light is incident.

The first top cover part 1216 is made of a non-conductive material and is made of a transparent material. The first and second electrode parts 1215 are formed by depositing a part of the bottom surface of the first top cover part 1216 .

Since the second liquid lens 1220 and the third liquid lens 1320 have substantially the same structure as the first liquid lens 1210, detailed description thereof will be omitted.

Here, the first 1-1 electrode unit 1213 and the second-1 electrode unit 1223 provided in the second liquid lens 1220 are electrically connected to each other, and the 1-2 electrode unit 1215 And the second -2 electrode unit 1225 provided in the second liquid lens are not electrically connected.

Here, the second electrode unit includes the first 1-2 electrode unit 1215 and the third -2 electrode unit 1325, and the second electrode unit is deposited on the top cover body 1400.

Here, when a voltage is applied to the first horizontal electrode 1230 and the first vertical electrode 1330, only the crossover lens, i.e., the first liquid lens 1210 is driven.

The switching unit 300 is controlled by the control unit 500 to apply a voltage to the first liquid lens 1210 and the second liquid lens 1220 so that the liquid in the first liquid lens 1210 The time at which the curvature of the interface is controlled and the time at which the curvature of the liquid interface at the second liquid lens 1220 is controlled are controlled to be different from each other.

As a result, although the 1-1 electrode unit 1213 and the 2-1 electrode unit 1223 are electrically connected to each other, the 1-2 electrode unit 1215 and the 2-2 electrode unit 1225 are not electrically connected to each other, the first liquid lens 1210 and the second liquid lens 1220 can be operated independently of each other by the switching unit 300.

By controlling the voltage applied to the first liquid lens 1210 and the voltage applied to the second liquid lens 1220 to be different from each other, the curvature of the liquid interface in the first liquid lens 1210, 2 curvature of the liquid interface at the liquid lens 1220 is controlled differently so that the focal distance of the first liquid lens 1210 and the focal distance of the second liquid lens 1220 can be controlled to be different from each other .

That is, the first electrode unit of the plurality of liquid lenses constituting one longitudinal column is connected to each other, and the second electrode unit of the plurality of liquid lenses constituting one row is connected to each other to simplify the voltage applying structure, A plurality of liquid lenses can be individually controlled by applying a voltage sequentially to the row lens array and the column lens array.

Here, when the voltage is applied to the first horizontal sensor electrode 215 and the first vertical sensor electrode 225, only the crossover sensor, that is, the first image sensor 211 is driven.

Next, a step of installing a control unit 500 for independently adjusting the respective focal lengths of the plurality of liquid lenses is performed.

Next, a coupling step of coupling the lens unit 100 to the outer surface of the support unit 700 is performed.

In the combining step, the first liquid lens 1210 and the second liquid lens 1220 have different heights with respect to the bottom surface of the support unit 700, and at the same time, they have a viewing angle central axis that is not parallel to each other The lens unit 100 and the support unit 700 are coupled to each other.

The reason for manufacturing the lens unit 100 on a two-dimensional plane is that a lithography process is applied to a housing body having a three-dimensional curved surface structure to form a housing space portion for accommodating the conductive liquid and the nonconductive liquid, It is difficult to deposit the first electrode part on the inner surface of the part or to coat the dielectric material on the inner surface of the first electrode part.

Accordingly, by manufacturing the lens unit 100 on a two-dimensional plane and coupling the lens unit 100 to a support having a three-dimensional curved surface structure, that is, the support unit 700, And the like.

The housing main body 110 of the lens unit is attached to the outer surface of the supporting unit 700 by an adhesive along the three-dimensional curved surface of the supporting unit 700. At this time, It is preferable that the housing main body 110 is made of a polymer material.

Here, the image sensor unit 20 may be installed on the accommodation space 111 before the liquid filling step (see Fig. 6 (b)).

The plurality of liquid lenses may be formed on the housing body 110 at the same time. For example, the deposition of the first electrode part, the coating of the dielectric part, the filling of the liquid, the step of installing the second electrode part, and the step of installing the top cover part are simultaneously performed on all the plurality of liquid lenses do.

That is, in the first electrode part deposition step, the first electrode part forming mask is used to simultaneously deposit on the inner surface of the accommodation space part 111. In the dielectric part coating step, Is coated on the inner surface of the first electrode part 113 at the same time and the liquid filling step can be simultaneously filled in all the accommodating space parts 111 formed in the housing main body.

The second electrode portion may be formed by depositing the second electrode portion on a part of the lower surface of the top cover portion using a mask for forming a second electrode portion. That is, the top cover part 116 is integrally formed, and after the second electrode part 115 is deposited at a predetermined interval on the lower surface of the top cover part 116, the top cover part 116, The upper surface cover portion mounting step may be completed by being attached to the upper portion of the upper surface cover portion 110.

The planar substrate mold 60 may be manufactured through a lithography process in the mold fabrication step.

It is difficult to form the accommodation space 111 by using a lithography process in the housing main body 110 having a three-dimensional shape, so that the housing main body 110 made of a polymer material is molded using the flat substrate mold 60 The plurality of liquid lenses are disposed on the three-dimensional curved surface by attaching the housing main body 110 to the support unit 700. [

As a result, the lens unit 100 is attached to the support unit 700 having a three-dimensional curved surface after implementing the plurality of liquid lenses in the housing main body 110 made of a polymer material on two dimensions, The liquid lenses are arranged on the three-dimensional curved surface.
