Description

Technical Field

[0001] This utility model relates to the field of optical instrument technology, and in particular to an optical lens and an optical instrument. Background Technology

[0002] As a key component of an optical system, an optical lens is defined by its ability to precisely refract and reflect light through a combination of lenses, thereby achieving focusing and high-quality imaging. Common types include single-lens lenses, compound-lens lenses, and aspherical lenses, each suitable for optical systems of varying complexity, meeting diverse needs from basic to high-end. In terms of applications, optical lenses are virtually ubiquitous, from everyday cameras and telescopes to microscopes and optical instruments in scientific research, and even high-tech optical communications, lasers, and semiconductor manufacturing—all relying on their powerful focusing and imaging capabilities.

[0003] Currently, optical lenses are mostly fixed using methods such as adhesive bonding, pressure ring fixing, and metal spring fixing. Among these methods, adhesive bonding requires high-temperature baking, which is time-consuming and energy-intensive; pressure ring fixing requires specific installation tools and the pressure ring is prone to deformation and jamming during operation, which can easily lead to the scrapping of the workpiece and lens; while using metal springs to fix the lens usually requires multiple metal springs, which takes up a lot of space and is not suitable for environments with limited installation space.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example 1

[0031] Reference Figures 1-8 As shown, an optical lens of this utility model includes,

[0032] The first lens holder 1 has a first stepped through hole coaxially formed on the first lens holder 1;

[0033] The second lens holder 2 has one end coaxially connected to one end of the first lens holder 1, and the second lens holder 2 is coaxially provided with an annular first extension 21 extending into the first step through hole;

[0034] The first lens assembly 3 includes a first lens 31, a first annular elastic member 32, and a first annular gasket 33. The first lens 31 is coaxially fitted into the first stepped through hole. The first annular elastic member 32 is coaxially disposed between the first lens 31 and the first extension 21 and is pressed onto the first lens 31 by the first extension 21. The first annular gasket 33 is coaxially disposed between the first lens 31 and the first annular elastic member 32.

[0035] Specifically, when assembling the optical lens, first place the first lens mount 31 on the operating table, then insert the first lens mount 31 into the first stepped through hole. Next, place the first annular shim 33 and the first annular elastic element 32 coaxially on the first lens mount 31. Then, align the second lens mount 2 with the first lens mount 1, so that the first extension 21 at the bottom of the second lens mount 2 is inserted into the first stepped through hole. Then, connect the second lens mount 2 and the first lens mount 1 with fasteners. During the fastening process, the first extension 21 will gradually press the first annular elastic element 32 onto the first lens mount 31, thereby completing the fixation of the first lens mount 31. Other lens mounts and lenses are assembled sequentially according to the same method and steps to complete the assembly of the entire optical lens.

[0036] This utility model discloses an optical lens with multiple lens mounts that can be sequentially connected and assembled into a lens barrel. Each lens mount serves as a support for mounting individual lenses. By providing extensions on the lens mounts in conjunction with annular elastic elements, when two adjacent lens mounts are connected, the lenses installed in the lens mounts can be pressed against the stepped surface of the mounting holes of the lens mounts by the extensions and annular elastic elements. During the connection of external lens mounts, the internal lenses can be fixed simultaneously, eliminating the need for fixing springs or using special tools to tighten clamping rings, simplifying the lens installation process and improving installation efficiency. The entire optical lens has a simple structure, is easy to install and maintain, and has high practicality.

[0037] Further, a third lens mount 4 is included, one end of which is coaxially connected to the end of the second lens mount 2 away from the first lens mount 1. The second lens mount 2 has a second stepped through hole coaxially provided, and the third lens mount 4 has an annular second extension 41 coaxially provided extending into the second stepped through hole. Specifically, this embodiment provides a specific structure for an optical lens, comprising a first lens mount 1, a second lens mount 2, a third lens mount 4, a fourth lens mount 6, and a flange mounting base 8 connected sequentially to form the lens barrel structure. A first lens 31, a second lens 51, a third lens 71, and a fourth lens 91 are respectively mounted in the first lens mount 1, the second lens mount 2, the third lens mount 4, and the fourth lens mount 6. Each lens is pressed into a mounting hole by an extension on another lens mount connected to its respective lens mount and an annular elastic element. It is conceivable that the fixing methods and structures of each lens are the same; different usage requirements can be met simply by adding or removing lens mounts and lenses according to different needs.

[0038] Reference Figure 2 , Figure 3 and Figure 4 As shown, the system further includes a second lens assembly 5, which comprises a second lens 51, a second annular elastic member 52, and a second annular gasket 53. The second lens 51 is coaxially fitted into the second stepped through hole. The second annular elastic member 52 is coaxially disposed between the second extension 41 and the second lens 51 and is pressed onto the second lens 51 by the second extension 41. The second annular gasket 53 is coaxially disposed between the second lens 51 and the second annular elastic member 52. Specifically, the annular gaskets coaxially disposed between each lens and the annular elastic member can protect the lens, further preventing damage to the lens during installation, thereby ensuring the final performance of the optical lens.

[0039] Furthermore, it includes a fourth lens holder 6, one end of which is coaxially connected to the end of the third lens holder 4 away from the second lens holder 2. The third lens holder 4 is coaxially provided with a third stepped through hole, and the fourth lens holder 6 is coaxially provided with a third extension 61 extending into the third stepped through hole. Specifically, the extensions on each lens holder are all integrally formed structures.

[0040] Further, the system includes a third lens assembly 7, which comprises a third lens 71, a third annular elastic member 72, and a third annular gasket 73. The third lens 71 is coaxially fitted into the third stepped through hole. The third annular elastic member 72 is coaxially disposed between the third extension 61 and the third lens 71 and is pressed against the third lens 71 by the third extension 61. The third annular gasket 73 is coaxially disposed between the third lens 71 and the third annular elastic member 72. Specifically, the annular elastic member between the lens and the extension ensures that the force ultimately applied to the lens is elastic, which can both firmly fix the lens and absorb vibration and impact energy, preventing the lens from breaking due to hard contact. Specifically, the annular elastic member can be a wave spring.

[0041] Furthermore, the system includes a flange mounting base 8, one end of which is coaxially connected to the end of the fourth lens mount 6 away from the third lens mount 4. The fourth lens mount 6 has a fourth stepped through hole coaxially provided, and the flange mounting base 8 has a fourth extension 81 coaxially provided extending into the fourth stepped through hole. Specifically, the flange mounting base 8 can also be considered a lens mounting base, except that it is used to connect to the fiber optic flange. However, its main structure is the same as that of a lens mounting base, and it also has an extension (i.e., the fourth extension 81) for use with the mounting hole of the lens mounting base to which it is connected.

[0042] Furthermore, it includes a fourth lens assembly 9, which includes a fourth lens 91, a fourth annular elastic member 92, and a fourth annular gasket 93. The fourth lens 91 is coaxially fitted into the fourth stepped through hole. The fourth annular elastic member 92 is coaxially disposed between the fourth extension 81 and the fourth lens 91 and is pressed onto the fourth lens 91 by the fourth extension 81. The fourth annular gasket 93 is coaxially disposed between the fourth lens 91 and the fourth annular elastic member 92.

[0043] Furthermore, the flange mounting base 8 has a threaded hole coaxially provided, which is used to install the fiber optic flange.

[0044] Reference Figure 1 As shown, the first lens holder 1 and the second lens holder 2 are further fastened together by a plurality of first screws, the second lens holder 2 and the third lens holder 4 are fastened together by a plurality of second screws, the third lens holder 4 and the fourth lens holder 6 are fastened together by a plurality of third screws, and the fourth lens holder 6 and the flange mounting seat 8 are fastened together by a plurality of fourth screws.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
