OPTICAL CHARACTERISTICS
– UIS series objectives not listed here can also be combined with this microscope. –
The following table shows the optical characteristics of
combinations of eyepieces and objectives. The figure
on the right shows the performance data engraved on
the objectives.

Distance between the top surface of cover glass and the objective front lens.
The figure corresponding to the F-number of the camera. This is associated with the resolu-
tion and larger NA means higher resolution.
Ability of an objective for identifying adjacent two lines in the image, which is expressed in
terms of the minimum distance between two points on the specimen surface.
The depth range of a specimen, in which focusing is obtained at a time. Stopping down
the aperture iris diaphragm increases the focal depth and increasing the objective NA
decreases it.
The diameter of the image observed through an eyepiece, represented in millimeters.
Diameter of the field of view, expressed as the size on the specimen surface.
