[1 mode] κ τ 4 will be described below with reference to the accompanying drawings The preferred embodiment is described in detail below in conjunction with the drawings. Referring to FIG. 1, a lens 1 of a preferred embodiment of the present invention includes a first sub-mirror 100 and a second sub-lens 200. Referring to FIG. 2, the first sub-lens 1 〇〇 includes a first optical surface 1〇2 having a first optical axis 302 and a first connection plane 104 opposite to each other. Specifically, the first sub-lens 1〇〇 is a circular lens including a first side 101 and a second side 1〇3 opposite to each other. The central portion of the first side 101 has a spherical projection 1〇7, which is spherical; the outer surface of the projection 1〇7 serves as a first optical surface 1〇2 of the first sub-lens 100. The first optical face 102 has a first optical axis 302. The central portion of the second side surface 1〇3 is provided with a first groove 1〇5 having a trapezoidal cross section. The first recess 105 includes a bottom surface (not shown) at a central portion of the first side surface 1〇1, which is a first connecting plane 104 of the first sub-lens 1〇〇. The first optical axis 302 is perpendicular to the first connection plane 1〇4. The second sub-lens 200 includes a second optical surface 202 having a second optical axis 304 and a second connecting plane 2〇4 that are opposite each other. Specifically, the second sub-lens 200 is a circular lens including a first side 201 and a second side 205 that are opposite each other. A central portion of the first side surface 2〇1 defines a second recess 203, and a bottom surface of the second recess 2〇3 serves as the second optical surface 2〇2 of the first sub-lens 200 and the second optical surface 2 〇2 is aspherical. The second sub-lens 200 is located at one end of the second side surface m to form an embedding portion 220. The embedding portion 220 and the first groove 1〇5 cooperate with each other and the first form number A0101 is 5th/14 pages 〇982073866-〇201122603 205 (ie, the top surface of the embedded surface) includes the first connecting plane 1〇4, and the first connecting plane is flat; the surface!〇4 is the area of the first connecting plane 104 of the disc-sweeping lens 100. [0012] [0012] When assembled, the first sub-lens (10) is fixed on the _ barrel (not shown), and then on the two sides 206 of the first connection plane 1 () 4 of the second sub-lens 2GG The first connection plane 104 of the second sub-lens 2 贴 is attached to the first connection plane 104 of the first sub-lens 1 涂 by applying an ultraviolet curing adhesive (1] v glue). Since the first groove 1〇5 has a trapezoidal cross section and the first connection plane 1〇4 of the second sub-lens 200 is planar and has an area equal to the area of the first connection plane 104 of the first sub-lens 100, the second sub-lens The first connection plane 104 of the second sub-lens 1 is easily positioned on the first connection plane 104 of the first sub-lens 1 ,, and excessively large between the first sub-lens 1 〇〇 and the second sub-lens 200 can be avoided. Eccentricity. At this time, the ultraviolet (ϋν) light source (not shown) is turned on to irradiate the UV glue, so that the UV glue is gradually solidified, and the first sub-lens 100 is adjusted by the UV glue during the irradiation process using an eccentric adjusting device (not shown). The angle between the connection plane 104 and the first connection plane 1〇4 of the second sub-lens 200 is adjusted to adjust the eccentricity of the lens 丨0 so that the first optical axis 302 and the second optical axis 304 are coincident. Since the first sub-lens 1 and the first sub-lens 200 are easy to clamp each other, and the eccentricity can be adjusted during the assembly process, the development and manufacture of the mold are avoided many times, and the cost of the mold is greatly reduced. This further reduces the production cost of the lens 10. In this embodiment, the first groove 105 has a trapezoidal cross section, and the first groove 105 further includes two side faces 218 connected to the second connecting plane 2〇4 (ie, the bottom surface), and the side surface 2 is 8 The orthographic projection of the connection plane 204 is outside of the second connection plane 204. It can be understood that the shape of the side surface 218 is not limited to the present invention 098143052 Form No. A0I01 0982073866-0 201122603 [0013], as long as the 正18 is projected by the second connection plane 204 in the second connection plane 2 & The embodiment of the spirit. Similarly, it can be understood that the cross section of the first recess 105 may also be square, in which case the orthographic projection of the side surface at the second connecting plane 2〇4 coincides with the edge of the second connecting plane 2〇4. It can be understood that the first groove 105 is opened to facilitate mutual positioning between the first sub-lens 1 〇〇 and the second sub-lens 200, and the positioning mode of the present invention is not limited to the second. [0014] It can be understood that the structural features of the first sub-lens 1 〇〇 and the second sub-lens 2 不 are not limited to the above embodiments, as long as the first side 1 〇 1 , 2 〇 1 has a spherical or aspheric surface ' The fact that the two sides 1 〇 3, 2 〇 5 have a plane is an embodiment of the spirit of the present invention. Meanwhile, the fixing manner between the first sub-lens and the second sub-lens 200 is not limited to the above-described implementation, [0015] It can be understood that in some special-purpose lenses, an optical axis 3〇2 or a Gth [ The two optical axes 304 may also not be perpendicular to the first plane 204, as the case may be. Connection Plane 104 or Second Connection In other embodiments, at least one lens 1 can be utilized to form a lens module 30. For example, referring to FIG. 3, in the present embodiment, the lens module 30 includes a lens barrel 4 and lenses 1 , 20 disposed in the lens barrel 4 . Wherein the lens 20 includes a first sub-lens 3 〇〇 and a second sub-lens 4 〇〇. The first sub-lens 300 and the second sub-lens 4 are similar to the structural features and combinations of the first sub-lens 1 and the second sub-lens 200, respectively. Those skilled in the art can know the specific structural features, groups and modes of the first sub-lens 3 〇〇 and the second sub-lens 400 from the above embodiments, and therefore will not be described again. 098143052 Form No. 1010101 Page 7 of 14 09820783866-0 201122603 [0017] It will be appreciated by those skilled in the art that the present invention is used only to refer to the present invention and not to sleep.
