Reference parameters for optical camera selection Postado em 07/03/2019 03:02 por by56014904


Optical accessories have multiple names, such as industrial cameras, industrial cameras, vision sensors, and the like. When it is photographed in an industrial environment, it is called an industrial camera; when it is recorded in an industrial environment, it is called an industrial camera with reference to the name of an ordinary civilian camera; when it is used for monitoring in an industrial environment, Named industrial camera or industrial probe; when it is used in industrial robots, it is called visual sensor.

The choice of customized plano/spherical/aspherical/cylindrical BaF2 optics accessories mainly includes two aspects: the choice of line array camera and the choice of area array camera. In the beginning, whether it is a line camera or an area camera, some parameters related to the camera need to be guided in advance.
1, resolution (here is the camera sensor imaging size): for example 1024pixel x 1024pixel;

2, frame rate (area camera): the number of images that can be taken per second;

3, line frequency (line array camera): the number of lines of images collected per second, in fact, the number of shots per second;

4, pixel size: the size of a physical pixel on the sensor, for example: 7.4um x 7.4um;

5, sensor size: the pixel size multiplied by the resolution is the sensor size;

6. Focal length: refers to the distance from the optical center of the lens to the focus of the light gathering when the parallel light is incident;

7. Object distance: the distance from the object to the efficient optical grade special shape sapphire optics of the lens;

8, optical magnification: in general, the fixed value, generally 0.35 times -2.25 times or 0.75 times -4.5 times;

9, working distance: that is, the object distance;

10, exposure time: in order to project light onto the photosensitive surface of the photographic photosensitive material, the time the shutter is to be opened;

11, the angle of view: the angle of the incident light at the edge of the lens

12. Target size: the size of the sensor image;

13. Accuracy: What is the size of the actual object represented by one pixel of the sensor;

14. Depth of field: The range of distances before and after the subject is measured by imaging at the leading edge of the camera lens or other imager.

When categorizing optical components, it is necessary to first analyze the working principle of the high precision custom optical prism components and the sub-objective requirements of the composition structure, and determine whether there is a storage device inside. Whether the shooting picture is mainly still picture or motion picture, not only the product name can be considered. , based on the name of the product to determine the classification.
