In the field of precision manufacturing, watch inspection has always been a key link in quality control. With its unique optical performance, the double telecentric lens has become an indispensable tool in watch inspection.

Biconvex lenses feature low distortion, high depth of field, and high resolution. These advantages are particularly evident in watch inspection. For transparent materials like watch glass, ordinary lenses are prone to interference from light refraction and reflection, leading to blurry images and making accurate inspection difficult. However, dual telecentric lenses effectively eliminate such interference, clearly revealing minor scratches, stains, and other defects on the glass surface, ensuring that every piece of watch glass meets high-quality standards.

In terms of watch size measurement, the double telecentric lens also performs exceptionally well. It can maintain a constant image size at different working distances, greatly improving measurement accuracy. When paired with professional image processing software, it can quickly and accurately obtain the size data of various watch components, providing a reliable basis for quality control during the production process.

Dual telecentric lenses with different magnifications play different roles in watch inspection. At a magnification of 0.16X, the lens can capture an overall image of the watch, facilitating a quick check of the overall integrity of the watch's appearance, such as whether the case is deformed or whether the decorative parts are complete.

A magnification of 0.7X allows you to focus on the details of the watch, such as the scale on the dial and the precision of the hands, so that you can clearly see every detail that may affect the quality.
