Type

MPLN

Eyepiece

Working distance: Distance between the surface of a specimen and the tip of the objective.

Aperture number: Essential value to determine the characteristics (resolution, depth of focus and brightness) of an

objective:
Resolution .......................................
Depth of focus ...........................
Brightness .......................................

Increases relative to the aperture number.
Decreases relative to the aperture number.
Changes in proportion with the square of the aperture number (the same
magnification comparison).

Resolution:

Represented by the interval between two points on a specimen which determine the ability of an
objective to distinguish two images close to each other.

Depth of focus:

The degree to which the portions of the image from front to back can be seen in focus simulta-
neously. The lower the aperture iris diaphragm, the greater the depth. The higher the aperture number,
the shallower the depth.

Field number:

The diameter of the area viewed through an eyepiece represented in millimeters.
