Through the ingenious structure design, the integral sphere can be flexibly adjusted in multiple dimensions. The opening and closing assembly 1 serves as the overall support structure, and the symmetrically installed front and rear translation screw slides 2 at the top of the opening and closing assembly 1 enable the integral sphere 4 to move forward and backward in the horizontal direction, meeting the needs of different measurement positions. The lifting assemblies 3 installed at the top of the front and rear translation screw slides 2 further endow the integral sphere 4 with the ability to lift in the vertical direction. The lifting frame 31 in the lifting assembly 3 and the vertically installed lifting screw 32 are connected and fixed with the two hemispheres of the integral sphere 4 through the lifting block 34, realizing the precise adjustment of the height of the integral sphere 4. This design not only improves the applicability of the integral sphere 4, enabling it to adapt to different sizes and shapes of measured light sources or detectors, but also greatly enhances the flexibility and accuracy of measurement.

[0026] In this embodiment, the top of the lifting screw 32 is driven to rotate by a lifting motor 33. By driving the lifting screw 32 to rotate through the lifting motor 33, the vertical movement of the lifting block 34 on the lifting screw 32 is realized, which in turn drives the lifting of the integral sphere 4. This electric driving mode is easy to operate, accurate in control, and can quickly and accurately adjust the height of the integral sphere 4, meeting different measurement needs.

[0027] Specifically, the horizontal sliding block of the front and rear translation screw slide 2 is connected and fixed with the bottom end of the lifting assembly 3, and the front and rear translation screw slide 2 is horizontally arranged. The design of the front and rear translation screw slide 2 enables the integral sphere 4 to move forward and backward in the horizontal direction. The connection and fixation of the horizontal sliding block with the bottom end of the lifting assembly 3 ensure the stability and accuracy during translation. This horizontal translation ability enhances the flexibility of the integral sphere 4, enabling it to more accurately align the measured light source or detector.

[0028] Further, the opening and closing assembly 1 comprises a shell 11, the shell 11 is installed with an opening and closing screw 12, the opening and closing screw 12 comprises two segments with opposite threads symmetrically arranged, the two segments are each installed with an opening and closing sliding block 14, and the top of the opening and closing sliding block 14 is connected and fixed with the bottom of the front and rear translation screw slide 2. The design of the opening and closing assembly 1 enables the two hemispheres of the integral sphere 4 to be conveniently opened and closed. The symmetric thread design of the opening and closing screw 12 realizes the opening and closing action of the integral sphere 4 through the movement of the opening and closing sliding block 14. This design not only facilitates the assembly and disassembly of the integral sphere 4, but also facilitates the replacement or adjustment of the internal components of the integral sphere 4.

[0029] Further, the top of the shell 11 is horizontally provided with a strip-shaped hole 111, the opening and closing slider 14 is in sliding fit with the strip-shaped hole 111, and one end of the opening and closing lead screw 12 is driven to rotate by the opening and closing motor 13. The strip-shaped hole 111 is designed to provide a sliding track for the opening and closing slider 14, thereby ensuring the stability and accuracy in the opening and closing process. The opening and closing motor 13 drives the opening and closing lead screw 12 to rotate, and the electric opening and closing of the integrating sphere 4 is realized through the movement of the opening and closing slider 14. This design makes the opening and closing operation more convenient and fast, and improves the work efficiency.

[0030] Further, the support assembly 5 comprises a threaded sleeve 51, the top of the threaded sleeve 51 is connected and fixed with the bottom of the opening and closing assembly 1, the bottom of the threaded sleeve 51 is threadedly connected with a threaded rod 52, and the bottom end of the threaded rod 52 is installed with a supporting leg 53. By rotating the threaded rod 52, the height and horizontal position of the integrating sphere 4 can be fine-tuned to ensure its stability during the measurement process. This design not only enhances the applicability of the integrating sphere 4, but also improves the measurement accuracy.

[0031] Further, the top of the opening and closing assembly 1 is installed with a level 6. By adjusting the support assembly 5 or the front and rear translation lead screw sliding table 2, it can be ensured that the integrating sphere 4 remains horizontal during the measurement process, further improving the measurement accuracy.

[0032] Further, the bottom of the supporting leg 53 is installed with a foot pad. When moving or adjusting the integrating sphere 4, the foot pad can play a buffering role to protect the integrating sphere 4 from being damaged. At the same time, the foot pad can also prevent the integrating sphere 4 from being displaced due to external vibration during the measurement process, thereby ensuring the stability of the measurement.

[0033] The adjustable optical integrating sphere of the utility model in use, first opening and closing assembly 1 as a whole support structure, its top symmetry installs two front and rear translation lead screw sliding table 2. Two sliding tables are horizontally arranged, which provides a basis for the front and rear translation of the integrating sphere 4 in the horizontal direction. The top of the front and rear translation lead screw sliding table 2 is installed with one lifting assembly 3 respectively, and the integrating sphere 4 is arranged between the two lifting assemblies 3. The integrating sphere 4 is composed of two hemispheres, and the two hemispheres are connected and fixed with the lifting sliders 34 on the outer side. The support assembly 5 is installed at the bottom of the opening and closing assembly 1, and the height and horizontal position of the integrating sphere 4 can be fine-tuned through the cooperation of the threaded sleeve 51 and the threaded rod 52.

[0034] The lifting frame 31 in the lifting assembly 3 is vertically installed with a lifting lead screw 32, and the lifting lead screw 32 is installed with a lifting sliding block 34.

Due to the thread cooperation between the lifting lead screw 32 and the lifting sliding block 34, the lifting sliding block 34 will move vertically on the lifting lead screw 32. The movement of the lifting sliding block 34 drives the half sphere connected thereto to move up and down, thereby achieving the lifting adjustment of the integrating sphere 4 in the vertical direction.

[0035] The design of the front and rear translation lead screw sliding table 2 enables the integrating sphere 4 to be translated forward and backward in the horizontal direction. When the front and rear position of the integrating sphere 4 needs to be adjusted, the horizontal sliding block of the front and rear translation lead screw sliding table 2 will move horizontally on the lead screw by driving the front and rear translation lead screw sliding table 2. The movement of the horizontal sliding block drives the front and rear translation lead screw sliding table 2 and the lifting assembly 3 connected thereto to move forward and backward, thereby achieving the forward and backward translation adjustment of the integrating sphere 4 in the horizontal direction.

[0036] The opening and closing assembly 1 includes a shell 11, and the shell 11 is installed with an opening and closing lead screw 12. The opening and closing lead screw 12 includes two symmetrically arranged threads opposite segments, and the two segments are installed with opening and closing sliding blocks 14. When the integrating sphere 4 needs to be opened or closed, the opening and closing motor 13 drives the opening and closing lead screw 12 to rotate. Due to the symmetric thread design of the opening and closing lead screw 12, the two opening and closing sliding blocks 14 will move in opposite directions on the opening and closing lead screw 12 at the same time. The movement of the opening and closing sliding block 14 drives the front and rear translation lead screw sliding table 2 and the lifting assembly 3 connected thereto to move, thereby achieving the opening or closing of the two half spheres of the integrating sphere 4. The strip-shaped hole 111 at the top of the shell 11 provides a sliding track for the opening and closing sliding block 14, ensuring the stability and accuracy during the opening and closing process.

[0037] The level 6 is installed at the top of the opening and closing assembly 1, which is used to observe the horizontal state of the integrating sphere 4. When it is found that the integrating sphere 4 is not horizontal, the horizontal position of the integrating sphere 4 can be calibrated by adjusting the threaded rod 52 in the supporting assembly 5 or the front and rear translation lead screw sliding table 2. The foot pad at the bottom of the supporting leg 53 plays a buffering role when the integrating sphere 4 is moved or adjusted, which protects the integrating sphere 4 from being damaged and prevents the integrating sphere 4 from being displaced due to external vibration during the measurement process.
