Application of air shower in optical film clean room

Wind shower room is a common facility of optical film clean room Optical thin films are mainly composed of thin layered media, which transmit light through the interface Nowadays, optical thin films have been widely used in the field of Optics and Optoelectronics Technology, manufacturing various optical instruments The optical thin films are characterized by smooth surface and geometrical interface The refractive index of the film can jump on the interface, but it is continuous in the film, it can be transparent medium, it can also be optical film absorbing medium, it can be normal uniform, it can also be normal inhomogeneous The practical film is much more complex than the ideal film The reason is that the optical and physical properties of the films deviate from the bulk materials, and the surface and interface of the films are rough, which leads to diffuse scattering of light beams and mutual penetration of the films to form a diffusion interface Due to the growth, structure and stress of the film, the anisotropy of the film is formed, and the film has complex time effect The optical films can be divided into reflection film, antireflection film, filter film, optical protection film, polarization film, spectroscopic film and phase film The first four are commonly used The optical reflective film is used to increase the specular reflectance It is often used to make reflective, refractive and resonant cavity devices Optical antireflection film is deposited on the surface of optical elements to reduce the surface reflection and increase the transmission of optical system, also known as antireflection film Optical filter film is used for spectral or other optical segmentation, which has many kinds and complex structure The optical protective film is deposited on the surface of metal or other soft erodible materials or films to increase their strength or stability and improve their optical properties Zui is a common protective film for metal mirrors The main reason why the air shower room is used in the optical film workshop is that the cleanliness of the optical film workshop is high, and the optical film can not have a little dust When entering the optical film production workshop, everyone must change into the clothes, hats, shoes and masks that the workers wear at work We were wrapped up so tightly that only one pair of eyes was exposed To pass through a "wind shower room" to remove dust, everyone is blown out of the wind shower room clean all over the body "bath" once Air shower room is one of the necessary purification equipment for employees to enter clean room and non clean room It can reduce the pollution caused by employees entering clean room to a large extent, and play a certain role in the management of optical film production workshop In other special clean workshops, there are also many production lines of 100 class super clean worktable Shanghai Sujing Industry Co., Ltd if you have any need, you can pass with us at any time Thank you very much for your support and look forward to cooperating with you Thank you & bestragard!
