What is the depth of field of a microscope? What is the depth of field of a microscope? Is there any difference between the depth of field of a microscope and that of a camera?
Generally speaking, when the position of the projection and the concave can be seen clearly through the object table observed in the field of view diameter, the height difference between the projection and the concave is the depth of field.
Generally, the depth of field of high power objective is smaller than that of low power objective.
The depth of field of a camera is much easier to understand. In photography, it means the distance between the near object and the distant object in the image. If the distance between the near object and the distant object in a photograph is very clear, the depth of field of the camera in the distance is very clear. The depth of field of the camera can be adjusted appropriately according to the effect that the photograph needs to show. Therefore, there are many factors affecting depth of field.
Influencing factors of depth of field:
1. The larger the numerical aperture of the objective, the smaller the depth of field, and the larger the numerical aperture, the smaller the depth of field.
2. If the product is not flattened, it will also have an impact.
3. In the process of debugging, the problem of light source will also affect the depth of field and so on.
Depth of field is not the criterion for judging the quality of a microscope. However, when two microscopes are selected under the same objective magnification, all points on the plane of the point can be seen clearly, and within a certain thickness of the plane above and below, it can also be seen clearly. The thicker the clear part is, the bigger the depth of field is. Mainly suitable for their own observation of the product can be.
