样品台采用三维手动精调平台，操作灵活，定位准确，样品台可根据实际样品尺寸定制；

采集系统采用黑白进口CCD相机，拍摄稳定，图像清晰，真实可靠，镜头采用德国工业级进口配置，0.7-4.5倍放大可调，成像无畸形失真；

The contact angle measuring instrument is mainly composed of a light source, injection unit, sample stage, acquisition system, and analysis software. The equipment adopts the principle of optical imaging. The light source uses a dense LED cold light design, with uniform light emission, clear images, and long lifespan. The injection unit adopts a high-precision injection pump for liquid feeding, controlled by software for quantitative and fixed-speed control, resulting in stable dripping and precision up to 0.01 microliters. The sample stage adopts a three-dimensional manual fine-tuning platform, with flexible operation and accurate positioning, and can be customized according to the actual sample size. The acquisition system uses an imported black and white CCD camera, providing stable shooting, clear and reliable images, and the lens uses German industrial-grade imported configuration, with adjustable magnification from 0.7 to 4.5 times, ensuring no distortion in imaging.
