Depth of field is the depth of the specimen clearly in focus and is greater at lower magnifications.
No published sn data.
As the magnification increases, the depth of field decreases.
Depth of field is best demonstrated with a slide containing overlapping threads. The depth of field that would increase is the low power objective.
The lines in each diagram represent an electric field. The stronger the field, the close together the lines are.
No its actually the opposite
The depth of field decreases.
A large aperture will not only allow you to have a higher shutter speed and to freeze action but also it will give you a narrower depth of field.
The higher the magnification the lower the depth of field.
The lines in each diagram represent an electric field. The stronger the field, the close together the lines are.
