Lens Cleaning Solution (UL0001): Piezoelectric Vibration for Continuously Clear Vision

Maintaining optical lens cleanliness in harsh or dynamic environments is critical for the reliable performance of imaging systems. The Lens Cleaning Solution UL0001 provides an advanced, reliable, and compact autonomous cleaning system designed to ensure consistently clear vision.

Based on the inverse piezoelectric effect of piezoelectric ceramics, UL0001 directly addresses challenges such as water droplet accumulation, frost formation, and light contaminant adhesion on lens surfaces.

Core Technology and Operating Principle

At the heart of the solution lies a precisely controlled physical mechanism. When a defined electrical drive signal is applied, the integrated piezoelectric ceramic element generates high-frequency mechanical deformation. This controlled vibration is transmitted to the lens itself or to a bonded substrate.

By operating under different vibration drive modes, the module generates tailored mechanical energy to effectively disrupt contaminant adhesion:

• Water Removal Mode
  High-frequency, low-amplitude vibrations generate standing or surface waves that shear water droplets, causing them to coalesce and roll off the lens surface.

• De-icing / Defrost Mode
  Specific vibration patterns disrupt the crystalline structure of frost or thin ice layers, enabling rapid detachment and melting.

This approach provides a non-contact, chemical-free, purely physical cleaning mechanism, ensuring efficient performance without additional consumables or mechanical wear.

Key Application Areas

The UL0001 solution is engineered for integration into systems where visual reliability is mission-critical:

• Automotive Cameras
  Ensures reliable performance of ADAS (Advanced Driver Assistance Systems), surround-view systems, and dash cameras under rain, snow, or freezing conditions—directly contributing to driving safety.

• Industrial Vision Systems
  Protects cameras used in manufacturing, robotics, and quality control from dust, oil mist, and splashes, minimizing downtime and maintenance requirements.

• Security and Surveillance Cameras
  Maintains continuous monitoring capability in all-weather conditions, preventing vision obstruction caused by rain, frost, or spider webs.

• Additional Applications
  Suitable for agricultural drones, outdoor sensors, and any sealed optical device requiring autonomous self-maintenance.

Advantages Over Traditional Cleaning Methods

Compared with conventional wiper or air-blowing solutions, this ultrasonic-based technology offers:
