1. Field Number (F.N.) and Practical Field of View

The field number (F.N.) is referred to as the diaphragm size of
eyepiece in mm unit which defines the image area of specimen.
The diaphragm diameter actually seen through eyepiece is
known as the practical field of view (F.O.V.) which is determined
by the formula:

F.O.V. =

Eyepiece F.N.

(mm)

Objective lens magnification

2. Working Distance (W.D.)

The distance between the front edge of the objective lens and
the specimen surface (with the surface of the cover glass in case
of the cover glass objective lens) when the specimen is focused.

3. Parfocal Distance

It is the distance between the objective lens mounting plane and
the specimen. In UIS2/UIS objective lenses, the parfocal
distance is designed at 45mm.

For parfocal distance of the LCPLFLN-LCD series objective
lenses, refer to the appropriate objective lens page.

4. Relationship between the objective lens's focal length

and magnifications

Indicated magnifications of UIS2/UIS objective lenses are the
values when the focal length of the tube lens is 180 mm.
