          How to choose a machine vision lens
          Author:Administrator   Published in:2019-11-09 09:23

          Machine vision systems use machines instead of human eyes to make measurements and judgments. Machine vision systems generally consist of: light source, lens, industrial camera, communication unit, capture card, storage system, image processing software and so on. The image sensor converts the optical signal of the target into an electrical signal, and then converts it into a digitized signal, and the image system processes the signals to acquire the characteristics of the target, and controls the action of the device according to the result of the discrimination. The quality of the lens directly affects the overall performance of the machine vision system, and it is essential to choose a suitable lens for clear imaging. Therefore, the choice of the appropriate machine vision lens has the following main points:

          1: Interface type:

          Type C: The distance between the C interface lens and the camera contact surface to the focal plane of the lens (the position where the camera ccd photoelectric sensor should be located) is 17.5mm.

          CS type: This distance is 12.5mm for the CS port. The CS lens can be used with the CS camera. A C/CS adapter ring must be added between the C-type lens and the CS-type camera to work together. The CS lens and the C-type camera cannot be used together.

          Type F: Universal interface, generally suitable for lenses with a focal length greater than 25mm.

          2: Field of view, optical magnification and desired working distance: When selecting the lens, we will select a lens that is slightly larger than the field of view of the measured object to facilitate motion control.

          3: Depth of field requirement: For projects with requirements for depth of field, use a small aperture as much as possible. When selecting a lens with a magnification, use a low-magnification lens as much as possible under the permission of the project. If the project requirements are harsh, choose a high depth of field. The cutting edge lens.

          4: Chip size: For example: 2/3 lens supports 2/3 of the largest industrial camera, which is an industrial camera that cannot support more than 1 inch.

          5: Pay attention to the cooperation with the light source: according to different light sources with different lenses, the most commonly used LED light source on the market.

          6: Installable space: It is unrealistic for customers to change the size of the device if the solution is optional.
