With the continuous development of automotive science and technology, vehicle cameras play a more and more important role in vehicle safety and driving assistance. 

In the application of vehicle camera, the contact angle measuring instrument has become a reference value. 

The contact angle measuring instrument is a kind of instrument used to measure the contact angle between liquid and solid. By measuring the contact angle, the wettability and adhesion of liquid on solid surface can be judged. 

The vehicle camera needs to avoid the gathering of water droplets and overcome the defect of blurring the panoramic camera view caused by the accumulation of water droplets, so the requirement for camera roll angle is very high. 

The inclined contact angle measuring instrument can effectively measure the rolling angle of the material surface, effectively characterize the forward and backward angle of the product surface, and evaluate the hydrophobic performance of the product surface.

The contact angle also affects the cleaning and maintenance of the lens. If the contact angle on the lens surface is large, water droplets or other cleaning liquids may slip more easily from the lens surface, resulting in poor cleaning effect. On the contrary, the appropriate contact angle helps to distribute the clean liquid evenly on the lens surface, thus removing pollutants more effectively.

The application of rolling contact angle measuring instrument not only improves the performance and reliability of vehicle camera, but also can evaluate the hydrophobic performance of product surface.
