In the fields of optics such as lighting, display, and sensing, the uniform distribution of light is the key to ensuring device performance. The diffuser (optical diffuser) processing technology becomes an optical engineer who regulates the propagation path of light by microstructuring the surface or interior of materials, and is widely used in scenes that require soft and uniform lighting. ​

In the field of display panels,Diffuser processing technologyHe is the mastermind behind the improvement of image quality. In the backlight module of a liquid crystal display (LCD), the diffuser converts the LED point light source into a uniform surface light source through a surface micro lens array (diameter 5-50 μ m) or internal scattering particles, increasing the brightness uniformity of the screen from 70% to over 95% and eliminating light and dark stripes. In MiniLED backlight technology, the use of microstructured diffusion sheets combined with zone controlled light can increase contrast by 10 times while reducing light loss (with a transmittance of 85%), balancing image quality and energy efficiency. Its precision molding process can mass produce micro scale structures, meeting the large-scale manufacturing needs of displays. ​

In the field of lighting and imaging, this process optimizes the efficiency of light utilization. In the operating room shadowless lamp, the diffuser scatters internal milky white particles, converting high-intensity light sources into soft diffused light with an illumination of 100000 lux without glare, avoiding visual fatigue caused by strong light for surgeons. In the light source module of the machine vision system, the diffuser plate evenly illuminates the surface of the object being tested with the light emitted by the LED, eliminating reflective interference and improving the accuracy of defect detection by 30%. In the design of car headlights, the diffuser is processed into specific texture patterns, which can shape the LED light into a light pattern that meets regulatory requirements (such as the cut-off line of low beam), while achieving dynamic light pattern adjustment for steering assistance. ​

In the field of sensing and laser, the diffuser processing technology expands the application scenarios of light beams. In LiDAR, the diffuser spreads the concentrated laser beam into a fan-shaped spot at a specific angle (10 ° -120 °), expanding the scanning range while maintaining uniform energy distribution, reducing signal attenuation during long-distance detection. In the infrared fill light for facial recognition, a micro nano structure diffuser is used to evenly cover the face area with infrared light, avoiding recognition failure caused by local overexposure. Its high-temperature resistant material (such as quartz glass) processing technology can adapt to high-temperature environments such as laser welding and industrial heating, and its diffusion performance remains stable at 200 ℃. In addition, in agricultural greenhouses, diffusion sheets can scatter sunlight and evenly irradiate crops, increasing plant photosynthesis efficiency by 15% and reducing shadow effects while increasing yield.
