Description

Technical Field

[0001] This utility model relates to the field of precision optical instrument technology, and in particular to an adjustable magnetic eyepiece holder. Background Technology

[0002] In high-precision optical systems such as two-photon fluorescence microscopes, key optical components such as dichroic mirrors and reflecting mirrors often need to be installed and replaced in the optical path to adapt to different experimental conditions or imaging requirements. Traditional frame structures generally fix optical components with threads or elastic clips. Although the structure is simple, it has the following shortcomings: 1) The disassembly and assembly steps are cumbersome, and frequent lens replacements cause operational inconvenience; 2) Repeated installation has low precision, which can easily cause optical path misalignment and affect imaging results; 3) Angle adjustment is inconvenient, making it difficult to meet the requirements of optical path fine-tuning and collimation. At the same time, as microscope systems develop towards modularity and miniaturization, optical modules are increasingly tending to be integrated into the internal space of the main unit, which places higher demands on the size and compactness of the frame. Traditional frames are large in size, their structure is not convenient for integration, and they are difficult to arrange flexibly in limited spaces.

[0003] A search revealed that application publication number CN110908061A discloses a rapid and precise positioning and fixing eyeglass frame, specifically comprising: a frame body and a base, and a positioning pin screw.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.

[0029] like Figure 1 and Figure 2 As shown, this utility model provides an adjustable magnetic lens holder, including a base 1, a lens mounting bracket 2, bolts, positioning pins 4, and positioning pins 5. The lens mounting bracket 2 is used to mount optical components such as dichroic mirrors and can be repeatedly positioned and disassembled from the base 1.

[0030] like Figure 2As shown, the base 1 is made of metal and includes a support part 10 and a mounting part 11. The support part 10 is a cuboid, and the mounting part 11 is a rectangular plate structure with a large surface area for mounting the lens mounting bracket 2. The mounting part 11 is perpendicular to the upper surface of the support part 10 and is located on the diagonal of the upper surface of the support part 10.

[0031] The support part 10 is provided with a first threaded hole 101, and the standard optical platform is provided with a second threaded hole. The bolt is screwed into the first threaded hole 101 and the second threaded hole to fix the base 1 on the standard optical platform.

[0032] The lower surface of the support part 10 is provided with a first positioning hole. If it is installed on the microscope body, a second positioning hole can be provided at the installation location. The positioning post 4 passes through the first positioning hole and the second positioning hole to assist in positioning the base 1 and ensure stable installation.

[0033] The mounting section 11 has a first light-transmitting hole 112 in the middle, and one surface is used to mount the lens mounting bracket 2. Each of the three corners of this surface has a threaded hole 114, and an adjustable fine-threaded screw 110 is screwed into each threaded hole 114. The heads of the three adjustable fine-threaded screws 110 are respectively abutted against the three corners of the lens mounting bracket 2. The adjustable fine-threaded screws 110 are used to achieve precise adjustment of the angle of the lens mounting bracket 2 by fine adjustment pressure. By rotating the screws, the plane of the lens 6 can be slightly tilted, thereby achieving fine adjustment of the optical axis to meet the needs of different incident angles or optical path collimation. Magnet mounting positions 115 are provided at the three corners of this surface, and magnets 3 are embedded in the magnet mounting positions 115. The two sides of this surface have third positioning holes 113.

[0034] like Figure 4 As shown, the lens mounting bracket 2 is a rectangular plate structure. A second light-transmitting hole 22 and a second groove 23 are opened in the middle of the lens mounting bracket 2, and the lens is installed in the second groove 23. Fourth positioning holes 21 are provided on both sides, and positioning pins 5 are fixed to the fourth positioning holes 21, passing through the third positioning hole 113. After insertion, they can restrict the movement of the lens mounting bracket 2 in the X and Y directions, achieving rapid and accurate initial positioning of the lens mounting bracket 2. Magnets 3 are installed on three corners of one surface of the lens mounting bracket 2, attracting each other with the magnets 3 on the mounting part 11, achieving rapid installation and firm fixation of the lens mounting bracket 2, while also possessing strong anti-disturbance capabilities, ensuring stability and repeatability during the experiment. A first groove 20 is provided on the edge of the lens mounting bracket 2 that contacts the mounting part 11, facilitating the removal of the lens mounting bracket 2.

[0035] Magnet 3 is a round neodymium iron boron magnet.

[0036] This invention utilizes a magnetic design for rapid assembly and disassembly, improving experimental efficiency. Positioning pins 5 ensure repeatable installation and prevent positional shifts. Adjustable fine-threaded screws 110 allow for micro-adjustment of the lens 6, facilitating optical path alignment. Its compact structure allows for embedding within optical equipment. The overall compact design makes it suitable for scenarios involving frequent replacement of optical components in high-precision optical systems. This invention does not affect the layout of other modules within the optical equipment and is particularly suitable for highly integrated, compact scientific imaging equipment or industrial optical systems.
