Industrial lenses are visual systems The main components in the system, the selection of industrial lenses affects the imaging results of the entire system. When doing visual inspection, you will encounter problems such as the inability to detect spatial objects, the inability to control changes in the field of view, the inability to control image distortion, low contrast, large distortion, reflection, etc. At this time, ordinary industrial lenses are not effectiveRwandans Sugardaddy handles the problem using a bi-telecentric lens. Rwandans Escort p>
The bi-telecentric lens can make up for the shortcomings of ordinary industrial lenses of “large near and small at far”. Its unique optical design allows the camera to receive parallel light, solve the detection accuracy problem caused by parallax, and can also avoid stray light. , ensuring clear and clear images
Molite bi-telecentric lens MTL series
Bi-telecentric lens is added to the optical system. Aspheric lens chip. Its working principle is based on the reasonable design of biconvex lens group and lens distance. In this design, the central optical axis of the two convex lenses is relatively upward, and the distance between the lenses is also appropriate. This special structure allows the bi-telecentric lens to have two telecentric and near-center cores at the same time.
When parallel light enters the bi-telecentric lens, they will be separated in two directions. It is refracted on a convex lens and converged on two different centers. These centers are called telecentric centers and near-center centers. The telecentric center refers to the point where the light converges far away from the convex lens group, while the near-center center refers to the point where the light converges farther away from the convex lens group. The light will Rwanda Sugar Daddy be focused at the closer point of the convex lens group
The peculiarity of the bi-telecentric lens. The point is that the position of the center can be changed by adjusting the lens distance. When the lens distance is large, the far-center center will move toward the direction of the camera, while the near-center center will move toward the direction of the light source. When the lens distance is small, the telecentric center will move toward the direction of the light source, while the near-center center will move toward the camera. This is achieved by adjusting the lens distance.Rwandans SugardaddyThe changed featureRwanda Sugar Daddyfeature makes the bi-telecentric lens in the shooting It is maneuverable and practical.
The structure of the bi-telecentric lens is compared with the ordinary Rwanda Sugar lens. There are more numbers and levels, so the price is relatively high. However, the advantages of bi-telecentric lenses are also very obvious. The shooting results are more clear and natural, and it is easier to express the depth of the subject.
Use of bi-telecentric lenses
01
Semiconductor chip inspection
In the field of semiconductor chip manufacturing, bi-telecentric lenses can be used for image measurement and inspection. In the manufacturing process of semiconductor chipsRwandans Escort, bi-telecentric lenses have beenRwanda Sugar ensures the quality and reliability of product tools through its high-precision and high-stability imaging system.
Chip detection generally requires a smaller field of view and higher accuracy requirements. Ordinary FA lenses cannot achieve higher accuracy. This requires the lens to have a large depth of field, so that clear images of different heights can be seen at the same time, improving measurement efficiency.
Since the bi-telecentric lens accepts parallel light, this feature makes the image contrast obvious, which is more conducive to software detection.

Transparent glass bottle defect detection
The material of the transparent glass bottle is easily affected by the external environment. In the case of light interference, it is not difficult to cause occlusion or whitening. The bi-telecentric lens has a special optical design that can effectively solve the light interference situation. RW EscortsClearly and correctly identify minor defects, such as scratches, white spots, etc.
The bi-telecentric lens not only has high resolution, but also has extremely low telecentricity and distortion, and the image is clearer, so the detection accuracy is very high, which can greatly improve the detection efficiency. And the quality of the stuff for giving birth to babies.
03
Car parts inspection
In the manufacturing of car parts, many precise optical inspection and measurement applications are involved. The bi-telecentric lens can reach different working distances and obtain clear visual images at the same time, thereby achieving Rwanda Sugar high precision at different distances. Optical measurement improves the efficiency and accuracy of assembly and quality inspection.

Telecentric Telecentric lenses and bi-telecentric lenses are often used in the field of precision measurement. The working distance of telecentric lenses and bi-telecentric lenses will not affect the imaging magnification within the depth of field, and the distortion value is very small. So how to choose during the selection process? Of course, bi-telecentric lenses win by strength.
Bi-telecentric lenses have a greater depth of field than telecentric lenses. When other parameters are the same, the working range of bi-telecentric lenses is the same. The working range is larger than that of the telecentric lens, and the range of observation is wider. When the height difference of the objects we need to observe is relatively large, we can give priority to the bi-telecentric lens.
Bi-telecentric lenses are also more telecentric than telecentric lenses. In the selection process of precision measurement, if the accuracy of the object to be measured is very high, the bi-telecentric lens will be a good choice. Take the shot of Maurit as an example.

The above mainly introduces the principle and advantages of the bi-telecentric lens Rwanda Sugar And some practical applications. Bi-telecentric lenses can also be used in various fields, such as the medical industry. It can effectively complete detection tasks, greatly improve detection accuracy, and help reduce costs and increase efficiency.
