In industrial manufacturing, for some high-precision, high-demand products, such as semiconductors, precision machinery, etc., surface defects may lead to product performance degradation or failure, so it is necessary to carry out strict quality control.

Product appearance defect detection is a very important link, can be timely found in the production process problems, to avoid product failure rate, improve production efficiency. Through the use of vision inspection systems, the surface of a product can be inspected and analysed with high precision to determine the presence of defects or flaws. In this process, Variable Focal Length FA Lens play an important role.

Variable Focal Length FA Lens can be adapted to different inspection needs by changing the focal length of the lens. In defect detection, better detection results can be obtained. Variable Focal Length FA Lens has the following advantages:

1. Flexible use and adaptability: the focal length of the Variable Focal Length FA Lens can be adjusted and can be adjusted according to different detection needs. This makes the Variable Focal Length FA Lens in the detection of different types of products has a stronger adaptability.

2. High resolution: the Variable Focal Length FA Lens can provide high-resolution images that can capture the minute details of the product surface, which is very favourable for the defect detection of some small precision products.

3. Fast focus: The Variable Focal Length FA Lenshas the ability of fast focusing, which can be completed in a short period of time to focus on objects at different distances. This makes fast inspection on the production line possible and improves production efficiency.

4. Space-saving: Variable Focal Length FA Lens have a small size and weight, which saves installation space and is easy to integrate with cameras and other image processing equipment.

The use of Variable Focal Length FA Lens for defect detection helps to increase productivity, reduce costs, improve product quality and ensure production safety.
