In the machine vision system, the role of the industrial lens is to image the target object on the photosensitive surface of the image sensor. The quality of the industrial lens directly affects the performance of the vision system. Zoom industrial lens is a kind of industrial lens, which refers to an optical lens whose magnification can be continuously and infinitely adjusted within a certain range. It has the characteristics of high contrast and high resolution. Excellent image quality is obtained, so it has a wide range of applications in vision systems.
The zoom industrial lens includes an electric zoom lens and a manual zoom lens. The working principle of the electric zoom lens is to use an electric motor and an integrated control card to control the software to adjust the magnification of the lens, and it can be achieved by observing the real-time computer screen. focus to get the clearest picture. The various components of the motorized zoom industrial lens play an important role. The structure of the motorized zoom lens includes the following parts:
1. Coaxial epi-illumination: The use of infinite parallel light incident can realize shadow-free illumination; the coaxial epi-illumination structure can make the illumination distribution of incident light more uniform.
2. Electric zoom: high-speed zoom speed and high-precision repeat positioning; imported DC servo motor; the electric control system implements single-axis or dual-axis control through a 9-pin RS-232 serial port; it can maintain mechanical stability.
3. Fixed scale and fixed magnification: mechanical positioning structure, excellent rate repeatability and stability; 15-stage mechanical positioning; high-hardness alloy material, long service life, strong and reliable mechanical structure design.
4. Fine-tuning device: It can be used in narrow spaces. Workpieces of different heights can be clearly focused by adjusting the fine-tuning structure without changing the original working distance of the lens; 3mm and 12mm fine-tuning structures can be provided; manual fine-tuning and electric-controlled fine-tuning structures can be provided.
Pomeas has a variety of magnification zoom industrial lenses such as 6.5x, 8x, 12.5x, welcome to consult and purchase.
