Walk-in hood is a device used to block or absorb light, commonly used in optical systems, optoelectronic equipment, laser equipment and other fields. It can be used to control the propagation path of light, reduce the interference of light and protect the effective work of optical instruments. In different application scenarios, the types, materials and manufacturing processes of walk-in shades vary. This paper will introduce the supply, application and manufacturing process of the walk-in hood.
First of all, the walk-in hood plays an important role in the optical system. In the fields of optical measurement, optical microscopy, optical imaging, etc., walk-in shades can be used to limit the propagation range of light and improve the clarity and resolution of imaging. At the same time, the walk-in hood can also be used to shield the stray light of the light source, reduce background interference, and improve the ratio of signal to noise. Therefore, in the design and debugging of optical system, the selection of appropriate walk-in hood can improve the quality of optical signal and improve the performance of the system.
Secondly, walk-in shades are also widely used in optoelectronic devices. Optoelectronic devices, such as photodiodes, photomultiplier tubes, photodetectors, etc., need to block out unwanted light and only receive light signals in a specified direction or wavelength. The walk-in hood can block and propagate the beam of a specific wavelength or direction by selecting the appropriate material and structure. These optoelectronic devices are usually used in optical communication, optical sensing, spectral analysis and other fields, and the requirements for walk-in shades are relatively strict, requiring high optical performance and stability.
In addition, walk-in shades also have important applications in laser equipment. As a kind of precision optical equipment, the laser needs to use a walk-in hood to limit the propagation range of the laser beam and prevent laser radiation from causing damage to the surrounding environment and the operator. The walk-in hood can choose a less transparent material to reduce the intensity of the laser beam through absorption or scattering. In addition, laser equipment also needs to use a walk-in hood to control the shape and focus of the laser beam to meet the needs of different application areas.
In the manufacturing process of walk-in hood, it is necessary to consider the selection of materials, processing technology and quality control. Commonly used walk-in hood materials are metal film, quartz, glass and so on. The metal film can be prepared on the surface of the substrate by evaporation, sputtering and other processes, which has a high shading effect and reliability. Quartz and glass materials have excellent optical and mechanical properties and are widely used in optical systems. In the manufacturing process, it is necessary to cut, grinding, polishing and other processes to make the surface finish and dimensional accuracy of the walk-in hood meet the requirements. In addition, it is also necessary to strictly control the environmental temperature, humidity and other conditions in the manufacturing process to ensure the quality and stability of the product.
In summary, as a device used to block or absorb light, walk-in hood has a wide range of applications in optical systems, optoelectronic equipment, laser equipment and other fields. When supplying walk-in shades, the appropriate materials and manufacturing processes need to be selected according to the needs of different application scenarios to meet the customer's requirements for optical performance, stability and cost. Through continuous innovation and improvement, we believe that the supply of walk-in shades will be further improved and developed.
