Principle of the zoom lens:

A zoom lens achieves a continuous change in focal length by changing the relative positions of the internal optical lens groups. A mechanical structure is usually used to drive the movement of the lenses, thereby adjusting the magnification of the lens. This design allows the user to flexibly adjust the size and detail of the observed object according to actual needs without changing lenses.

Characteristics of the zoom lens:

1. Precision optical path design, high resolution, low distortion and excellent optical performance. This means that the zoom lens is able to provide clear and accurate images, which is important for applications that require fine observation and measurement.

2. Extra-long working distance, large field of view observation range. It can be used to observe objects at a longer distance, and at the same time, it can cover a larger field of view, which is convenient for users to have a comprehensive observation of objects of different sizes.

3. Multi-layer coating technology, reducing stray light and ghosting, providing high-quality images. Coating can effectively increase the light transmission of the lens and reduce reflection and scattering, thus improving the contrast and color reproduction of the image.

4. Anodized metal parts are more durable. This treatment can enhance the corrosion and abrasion resistance of the metal parts and prolong the service life of the lens.

5. Compact and reliable design. It is easy to install and use, and at the same time can ensure the stability and reliability in various working environments.

The purpose of the zoom lens:

1. Biological field: it can be used for cell observation, tissue section analysis and so on. High resolution and large field of view observation range enable researchers to observe the details of biological samples more clearly, while the ultra-long working distance can avoid damage to the samples.

2. Electronic industry: can be used for circuit board inspection, chip package inspection, etc.. The zoom lens can provide clear images to help inspectors find tiny defects and problems to ensure the quality of electronic products.

3. Semiconductor industry: it can be used for wafer inspection, chip manufacturing process monitoring, etc.. Its high resolution and low distortion are crucial for high precision inspection in semiconductor manufacturing.

4. Machine vision field: the zoom lens can be used in conjunction with cameras and image processing systems to realize automated inspection and measurement. For example, in industrial production lines, the size, shape and surface quality of products can be monitored in real time to improve productivity and product quality.

POMEAS zoom lenses are indispensable optical tools in the high precision industry due to their excellent optical performance, flexible zoom function and wide range of applications.
