Advantages of Ultrasonic Spraying for Microlens Coating
Advantages of Ultrasonic Spraying for Microlens Coating In high-end manufacturing sectors including micro-optics, optoelectronics, semiconductor imaging and sensing, the uniformity, thickness precision, surface quality and structural consistency of microlens coatings directly determine the focusing efficiency, transmittance, imaging resolution and long-term reliability of optical components. Conventional coating techniques such as spin coating, dip coating and air-pressure spraying are plagued by inherent bottlenecks in droplet regulation, material compatibility, substrate adaptability [...]
