Focusing of Drum Lenses in the Right Field of View

4-1) Rotate drum to position 16X, insert eye- 4-1)

piece GlOX into right eyepiece tube, and

Use eyepiece GlOX

(f=25~and

focus with focusing telescope.

4-2) Check deviation direction of focus at

40X and 6.3X in comparison with 16X.

a. In case focus is "below" at 6.3X in

comparison with 16X, move prism P2

forward until focuses of 40X and

6.3X are in the same direction and

equidistant.

b. In case focus is "below'' with drum

lens 6.3X, move prism P2 forward

until focuses of 40X and 6.3X are in

the same direction and equidistant.

4-3) Coincide focus of 40X and 6.3X to that

of 16X.

a. If focus of 6.3X is above that of

focusing telescope should be

matched for focusing with this

eyepiece.

If microscope main body has to be

moved upward with focusing knobs

to obtain correct focus, this

state is called "focus is above":

on the contrary, if main body has

to be lowered, it is called "focus

is below''.

rotating two setscrews counterclock-

wise equally.

b. If focus of 40X is below that of 16X,

lower 40X drum lens by rotating two

setscrews clockwise equally.

4-4) Coincide focus of 25X and lOX to that

of 16X.
