[0029] See also Figure 1 and Figure 3An optical system includes an optical platform 200, an optical assembly 100 disposed on the optical platform 200, and a second optical module 300 disposed on the optical platform 200. The optical platform 200 and the second optical module 300 can be found in the optical system disclosed in Chinese Patent Application No. 202210186150.0. The second optical module 300 is equivalent to the combination of the positioning block and the optical components disposed thereon described in the patent. Therefore, the specific structures of the optical platform 200 and the second optical module 300 are not further described here. The second optical module 300 may have multiple functions, either identical or different.

[0030] In this embodiment, the optical assembly 100 is a cage-type structure, comprising a stand 1, a cage plate 2, and cage rods 3. The stand 1 is U-shaped and comprises a base plate 11 and arms 12 located at opposite ends of the base plate 11. The base plate 11 is a flat plate, and the two arms 12 are parallel to each other. The upper surface of the base plate 11 and the surfaces of the two arms 12 approaching and separating from each other are all flat. The base plate 11 can be fixed to the optical platform 200. Each arm 12 is provided with a through-hole 121. The through-hole 121 is a circular hole, and the distance between its center and the bottom surface of the base plate 11 is h, which is the central optical height of the stand 1. In this embodiment, h is 40 mm. The width of the stand 1 is d. Optionally, d can be 40 mm to facilitate compatibility with a second optical module 300 (the applicant's 40 mm optical building block, as shown in the prior application in the background art, which is used to build optical devices in the form of building blocks, referred to as optical building blocks). Thus, a hybrid system of optical building blocks and cage structures can be constructed. Parts of the system that require high precision and high stability can be built using optical building blocks (the second optical module 300), and parts that require flexibility can be built using cage structures (optical components 100). Figure 1 As shown in .

[0031] There are at least two cage plates 2, located between the two arms 12. In this embodiment, there are four cage plates in total, three of which are spaced apart between the two arms 12. Cage rods 3 pass through these three cage plates 2 and the arms 12, thereby fixing the positions of the cage plates 2 and the gantry 1 relative to each other. Another cage plate 2 is mounted on the cage rods 2 and arranged perpendicularly relative to the other three cage plates 2. Each cage plate 2 has a mounting hole 21. The mounting holes 21 on the three cage plates 2 passed through by the cage rods 3 are aligned with each other and with the through-holes 121 on the gantry 1. Another cage plate 2 mounted on the cage rods 3 provides the possibility of setting more directional light paths. The required optical functional components of the peripheral device (not shown) can be fixed to the mounting holes 21.

[0032] Preferably, the cross-section of the cage plate 2 is roughly rectangular, such as a square with rounded corners. Therefore, there are preferably four cage rods 3, which pass through the four corners of the cage plate 2 and the support arms 12 respectively. Holes can be opened in the support arms 12 and the cage plate 2 to facilitate the passage of the cage rods 3 and thereby position the cage rods 3.

[0033] Example 2

[0034] See 4~ Figure 6 In this embodiment, the difference from the above-mentioned embodiment 1 is that the optical assembly 100 is no longer a cage structure, that is, the cage plate 2 and the cage rods 3 are no longer provided, but a collimator 4 is provided.

[0035] Each arm 12 is provided with a fixing hole 122, which is a screw hole, which is provided around the through-hole 121. Optionally, the number of the fixing holes 122 is 3, which are evenly spaced along the circumference of the through-hole 121. The surfaces of each arm 12 that are away from each other constitute a mounting surface 123, and the two mounting surfaces 123 are parallel to each other. The mounting surfaces 123 can be processed by CNC processing technology, so as to have a high degree of parallelism. There are two collimators 4, each of which is respectively mounted on a side of a arm 12 away from the other arm 12, and a fastener such as a screw is used to pass through the collimator 4 and the fixing hole 122, so as to fix the collimator 4 to the arm 12, and fit with the mounting surface 123 of the arm 12. In this way, light coupling of the collimators 4 on both sides can be achieved.

[0036] In addition, a first optical function device 5 can be installed on the base plate 11 between the two arms 12 to achieve different functions. The first optical function device 5 is an optical device with a certain function, such as a polarizer, a turntable, a mirror frame, and an aperture. In this embodiment, there are four first optical function devices 5, which may include two turntables. The turntables are used to adjust the refraction angle of light. Existing technology can be used. For details, please refer to the device for achieving continuous refraction angle adjustment using a double wedge plate disclosed in the applicant's Chinese patent application number 201922204379.9. By setting up the turntable, the fiber-to-fiber coupling efficiency can be optimized. In addition, a turntable, a mirror frame, and an aperture can be installed between the two turntables to achieve different functions. First optical function devices 5 with different structures and functions can be fixed to the base plate 11 of the stand 1 by selecting a suitable base.

[0037] Example 3

[0038] See also Figure 7In this embodiment, the difference from the above-mentioned embodiment 2 is that a first optical module 6 is used to replace the above-mentioned first optical functional device 5. The first optical module 6 is the same as the second optical module 300, including a positioning block 61 and a second optical functional device 62 arranged on the positioning block 61. The positioning block 61 is fixed to the base plate 11. The second optical functional device 62 is the same as the first optical functional device 5, such as a polarizer, a rotating disk, a mirror frame and an aperture.

[0039] This allows the optical module to be mounted directly on the optical platform 200 or indirectly via the stand 1 of the optical assembly 100. In this case, the first optical module 6 can be selected to have an optical height of, for example, 25 mm, which, after assembly, can be aligned with the optical height of the support arm 12. The stand 1 of the optical assembly 100 thus forms a small optical platform.

[0040] Alternatively, in this embodiment, the collimator 4 may not be provided.
