Maintaining the cleanliness of optical lenses in harsh or changing environments is crucial for imaging systems. The Ultrasonic Lens Cleaning Solution (UL0001) offers an advanced, reliable, and compact autonomous lens cleaning solution. Based on the inverse piezoelectric effect of piezoelectric ceramics, this solution directly addresses challenges such as water droplet accumulation, frost formation, and light dirt adhesion on lens surfaces.
Core Technology and Working Principle
The core of this solution lies in the utilization of precise physical phenomena. When a specific electrical drive signal is applied, the integrated piezoelectric ceramic element generates high-frequency mechanical deformation. This controlled vibration is transmitted to the lens or the substrate bonded to it. By operating in different vibration drive modes, the module generates tailored mechanical energy to disrupt the adhesion of contaminants:
Water Removal Mode: High-frequency, relatively low-amplitude vibrations generate standing or surface waves, shearing water droplets, causing them to coalesce and roll off.
Defrosting Mode: Specific vibration patterns can disrupt the crystal structure of frost or thin ice layers, promoting rapid peeling and melting.
This method provides a non-contact, chemical-free, purely physical cleaning mechanism.
Applications
The UL0001 solution is specifically designed for integration into systems where visual reliability is paramount:
Vehicle-Mounted Cameras: Ensures functionality of ADAS (Advanced Driver-Assistance Systems), surround-view systems, and dashcams in rain, snow, and freezing rain—critical for safety.
Industrial Lenses: Protects vision systems in manufacturing, robotics, and quality control from dust, oil mist, and splashes, minimizing downtime.
Security Cameras: Maintains continuous monitoring capabilities in all-weather conditions, preventing view obstruction caused by rain, frost, or spider webs.
Other Fields: Equally suitable for agricultural drones, outdoor sensors, and any enclosed optical equipment requiring self-maintenance.
Compared to traditional wiper or air-blowing methods, this ultrasonic solution features:
Compact and Easy to Integrate: Its thin design facilitates seamless integration into products.
Low Power Consumption: Efficient operation, suitable for always-on systems.
High Reliability & Long Lifespan: Solid-state design with no moving parts contacting the lens.
Efficient and Versatile: Capable of addressing both liquid and solid contaminants simultaneously.
