Description

Technical Field

[0001] This utility model relates to the field of integrating sphere technology, and more specifically, to a high-efficiency optical integrating sphere with multiple coating materials. Background Technology

[0002] In the field of optical measurement and analysis, the integrating sphere, as an important optical device, is widely used in various aspects such as luminous flux measurement, spectral analysis, light source characteristic testing, and optical system calibration. The basic principle of the integrating sphere is to utilize its internal highly reflective surface to diffusely reflect incident light multiple times, thereby achieving uniform light distribution and collection, and thus accurately measuring relevant light parameters.

[0003] Traditional integrating spheres typically employ a single material or a single-structure reflective coating to enhance their internal reflectivity. However, this design often suffers from insufficient reflectivity, limited spectral response range, and poor durability. Especially when measuring wide spectral ranges or high-brightness light sources, the performance of a single coating material is often insufficient, limiting the measurement accuracy and efficiency of the integrating sphere.

[0004] In addition, traditional integrating spheres are often structurally complex, inconvenient to assemble and maintain, and the reflective coating is not securely fixed, making it prone to falling off or being damaged during use, which further affects the stability and service life of the integrating sphere. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency optical integrating sphere with multiple coating materials, in order to solve the problems mentioned in the background art. Traditional integrating spheres usually use a single material or a single structure of reflective coating to improve their internal reflectivity. However, such designs often have problems such as insufficient reflectivity, limited spectral response range, and poor durability.

[0006] To achieve the above objectives, this utility model provides a high-efficiency optical integrating sphere with multiple coating materials, comprising a sphere, a bracket mounted on one side of the sphere, a base mounted on the bottom end of the bracket, the sphere comprising a left hemispherical shell and a right hemispherical shell, a reflective component mounted on the inner wall of the left and right hemispherical shells, the reflective component comprising a base layer, and a coating layer mounted on the inner sidewall of the base layer.

[0007] Preferably, the sides of the left and right hemispherical shells are connected and fixed by a flange structure.

[0008] Preferably, the left and right hemispherical shells are locked and fixed to the reflector assembly by countersunk bolts.

[0009] Preferably, a light-entry hole is provided on one side of the outer wall of the left hemisphere, and an observation hole is provided on the top outer wall of the left hemisphere.

[0010] Preferably, the outer wall of the base layer is provided with several threaded grooves, one end of the countersunk bolt is threadedly connected to the threaded grooves, and the outer walls of the left and right hemispheres are provided with grooves with bottom holes near the countersunk bolts, and the end of the countersunk bolt is stuck in the groove.

[0011] Preferably, the coating layer includes a first coating, a second coating, and a third coating, wherein the back side of the first coating is bonded and fixed to the inner wall surface of the base layer.

[0012] Preferably, the base layer comprises two hemispherical shell-shaped structures, with the outer wall attached to the inner wall of the sphere.

[0013] Preferably, the first coating is a metal oxide, the second coating is a metal layer, and the third coating is a protective layer made of an insulating film material.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This high-efficiency optical integrating sphere, composed of multiple coating materials, effectively improves the reflectivity inside the sphere by employing a coating layer made up of various materials. This allows light to undergo more thorough diffuse reflection within the sphere, resulting in a more uniform light distribution. The combination of multiple coating materials also broadens the spectral response range of the integrating sphere, making it suitable for a wider range of spectral measurements and analyses, meeting the needs of more application scenarios. Furthermore, it is easy to assemble and disassemble, facilitating maintenance after long-term use.

[0016] The protective layer in the coating is made of insulating film material, effectively protecting the underlying metal and metal oxide layers and improving the coating's durability and resistance to damage. The reflective component is tightly locked to the sphere using countersunk bolts, and the outer wall of the base layer has threaded grooves to mate with the countersunk bolts. Simultaneously, the outer wall of the sphere has a recessed groove with a bottom hole to accommodate the end of the countersunk bolt. This fixing method is more secure and reliable, preventing the reflective coating from peeling off or being damaged during use.

[0017] The integrating sphere adopts a split design with a left and right hemisphere shell, connected and fixed by a flange structure, making the assembly and maintenance of the integrating sphere more convenient and quick. The placement of the light inlet and observation port also takes into account the convenience of practical use, facilitating the input of the light source and the connection of measuring equipment.

[0024] 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 embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This invention provides a high-efficiency optical integrating sphere with various coating materials, such as... Figures 1-4 As shown, the integrating sphere includes a sphere 1, a support 3 mounted on one side of the sphere 1, and a base 2 mounted on the bottom of the support 3. The sphere 1 includes a left hemispherical shell 12 and a right hemispherical shell 11. A reflective assembly 4 is mounted on the inner wall of the left hemispherical shell 12 and the right hemispherical shell 11. The reflective assembly 4 includes a base layer 41, and a coating layer 42 is mounted on the inner side wall of the base layer 41. Through ingenious design, the sphere 1 is divided into a left hemispherical shell 12 and a right hemispherical shell 11, and a reflective assembly 4 is mounted on its inner wall. The reflective assembly 4 is composed of a base layer 41 and a coating layer 42. This multi-layer structure design significantly improves the optical performance of the integrating sphere. Specifically, the coating layer 42 can efficiently reflect incident light, while the base layer 41 provides stable support for the coating layer. In addition, the support 3 and the base 2 mounted on one side of the sphere 1 not only provide stable support for the integrating sphere, but also facilitate its arrangement and use in practical applications. This structural design allows the integrating sphere to maintain high reflection efficiency while also possessing good practicality and convenience, providing a more efficient and stable tool for optical measurement and analysis.

[0026] In this embodiment, the left hemispherical shell 12 and the right hemispherical shell 11 are connected and fixed to each other via a flange structure 14. The flange structure 14 provides a stable and reliable connection between the left hemispherical shell 12 and the right hemispherical shell 11, ensuring the integrity and sealing of the sphere 1. This connection method facilitates disassembly and assembly, which is beneficial for the maintenance and upgrading of the integrating sphere.

[0027] Specifically, the left hemisphere 12 and the right hemisphere 11 are secured to the reflector assembly 4 using countersunk bolts 13. The use of countersunk bolts 13 not only firmly fixes the reflector assembly 4 to the inner wall of the sphere 1, but also ensures the flatness and stability of the reflective surface. This fixing method effectively prevents the reflector assembly 4 from loosening or falling off during use, improving the durability and reliability of the integrating sphere.

[0028] Furthermore, a light inlet 122 is provided on one side of the outer wall of the left hemisphere 12, and an observation hole 121 is provided on the top outer wall of the left hemisphere 12. The design of the light inlet 122 allows light to enter the interior of the integrating sphere smoothly, while the observation hole 121 provides a convenient channel for measurement and observation. This design makes the integrating sphere more flexible and convenient to use, meeting the needs of different application scenarios.

[0029] Furthermore, the outer wall of the base layer 41 is provided with several threaded grooves 411. One end of the countersunk bolt 13 is threaded into the threaded groove 411. The outer walls of the left hemisphere 12 and the right hemisphere 11 are provided with grooves with bottom holes near the countersunk bolt 13, and the end of the countersunk bolt 13 is stuck in the groove. The design of the threaded grooves 411 and the grooves with bottom holes allows the countersunk bolt 13 to be firmly fixed to the base layer 41 and the sphere 1, while maintaining the flatness of the inner surface of the sphere 1. This design improves the structural strength and stability of the integrating sphere, ensuring its reliability during long-term use.

[0030] Furthermore, the coating layer 42 includes a first coating 421, a second coating 422, and a third coating 423, with the back side of the first coating adhered and fixed to the inner wall surface of the base layer 41. This multi-layer coating structure design improves the reflection efficiency and spectral response range inside the integrating sphere. The combined use of the first coating 421, the second coating 422, and the third coating 423 allows the integrating sphere to adapt to a wider range of applications, improving its measurement accuracy and efficiency.

[0031] Furthermore, the base layer 41 comprises two hemispherical shell-shaped structures, with the outer walls fitted against the inner wall of the sphere 1. The hemispherical shell design of the base layer 41 fits tightly against the inner wall of the sphere 1, providing excellent support and fixation. This design allows the reflective components 4 to be evenly distributed inside the sphere 1, improving the optical performance of the integrating sphere.

[0032] Furthermore, the first coating 421 is a metal oxide layer, which directly contacts the substrate material of the integrating sphere (such as aluminum alloy, carbon steel, etc.). Its main purpose is to improve the adhesion between the functional layer and the substrate, ensuring the stability and durability of the coating. Simultaneously, by adjusting the optical properties and color of the film system, the performance of the integrating sphere can be further optimized. The second coating 422 is a metal layer, which is the core of the coating inside the integrating sphere and directly affects its reflectivity and optical performance. The metal layer can efficiently reflect light, ensuring that the light achieves a uniform distribution after multiple reflections inside the integrating sphere. The third coating 423 is a protective layer made of insulating film material. This layer mainly serves to reduce reflection and protect the functional layer from external environmental corrosion (such as moisture, oxidation, etc.), thereby extending the service life of the integrating sphere.

[0033] In use, the high-efficiency optical integrating sphere of this invention, which utilizes various coating materials, first allows light to enter the sphere through a light-entry hole located on the outer wall of the left hemisphere shell 12. This design ensures that light can enter the sphere smoothly and uniformly, providing a basis for subsequent reflection and measurement.

[0034] The light entering the integrating sphere first comes into contact with the reflective component 4, which consists of a base layer 41 and a coating layer 42. The coating layer 42 includes a first coating 421, a second coating 422, and a third coating 423, which have different functions and properties.

[0035] The first coating 421 serves as an adhesive layer to the substrate material, improving the stability and durability of the coating. The second coating 422, as a metallic layer, is the core of the reflection, efficiently reflecting light and ensuring that the light reaches a uniform distribution after multiple reflections inside the integrating sphere. The third coating 423 serves as a protective layer, preventing the functional layer from being corroded by the external environment and extending the service life of the integrating sphere. Due to the spherical design of the integrating sphere and the efficient reflection characteristics of the reflecting components, the light gradually reaches a uniform distribution after multiple reflections inside the sphere 1. This uniformly distributed light provides a stable and reliable light source for optical measurement and analysis. Measurement and observation can be conveniently performed through the observation hole 121 provided on the outer wall of the top of the left hemisphere shell 12.

[0036] The design of the observation aperture 121 makes the integrating sphere more flexible and convenient to use, meeting the needs of different application scenarios. The left hemisphere 12 and the right hemisphere 11 are connected and fixed by the flange structure 14, providing a stable and reliable connection method and ensuring the integrity and sealing of the sphere 1. The reflective assembly 4 is firmly fixed to the inner wall of the sphere 1 by countersunk bolts 13, ensuring the flatness and stability of the reflective surface. The outer wall of the base layer 41 is provided with several threaded grooves 411, which are threadedly connected to the countersunk bolts 13, further improving the structural strength and stability of the integrating sphere.
