The zoom lens is a kind of optical lens whose magnification can be continuously and infinitely adjusted within a certain range, which is a very important component in the field of industrial automation, and can achieve clear observation and identification of objects. Industrial zoom lens as a lens with a zoom function, its application is very wide, such as the following scenes:

1. Chip character detection: industrial zoom lens can magnify the characters on the chip to a clear and easy to observe state, thus facilitating workers to identify and detect. To ensure the quality and reliability of the chip.

2. Appearance Inspection: Industrial zoom lens can be used for product appearance inspection, such as detecting whether there are scratches, deformation, colour difference and other defects on the surface of the shell to ensure the quality and aesthetics of the product.

3. Gold finger detection: industrial zoom lens can be used for the detection of gold finger, the gold finger will be enlarged several times, so that the inspector can see the image more clearly, and accurately identify whether there is an appearance of defects.

4. Circuit board inspection: circuit boards are the basic components of electronic equipment, industrial zoom lens for circuit board inspection. The circuit board image can be enlarged several times, can more clearly see the circuit board lines and components whether there are defects, in order to ensure the reliability and performance of electronic equipment.

5. Inductive resistance detection: inductive resistance is a precision parts, processing and manufacturing process may produce broken, nicked and other defects, installed in the product will affect the performance of the product, so you need to do a strict quality inspection. The use of industrial zoom lens composed of vision inspection programme, can be inductive resistor image magnified several times, and to preserve the clarity of low distortion, accurate identification of defects.

Industrial zoom lenses are widely used in biology, semiconductor, electronics, machine vision and other high-precision industries, with large field of view, high definition, high resolution, low distortion and other advantages, which can make the inspection results more accurate and reliable. Improve production efficiency and product quality.
