Attachable Mechanical Stage Type "E - Nikon LABOPHOT-POL Instructions Manual

Iy using the clamp screw on the illuminator
"M".
Secure clamping of the tube is to be done
after completing the orientation of analyz-
er
2)-(2).
]:: Referring to P. 7, mount the eyepiece tube
on the intermediate tube "P".
2) Preparation
(1) Centering the lamp
CD
Turn the half-reflecting mirror swing-out

center the filament image on the exit pupil.
®
Place the L filter.
If the image is found too dark with an
objective of 40X or higher, remove the L
filter.
(2) Orientation of analyzer (intermediate tube
liP")
CD
Nearly focus on the ND filter on the stage
using objective 40x.
@
Set the analyzer graduation to "0".
®
Slightly release the intermediate tube
clamp screw on the epi-illuminator "M",
detect the orientation of the intermediate
tube "P" to form the dark cross image on
the exit pupil of objective (Refer to Fig.
13), and in th is position clamp the inter-
mediate tube "P".
3) Objectives
Use the objectives CF M Plan Achromat P

To attach the attachable stage on the graduated
stage, fit the tWo positioning pins on the rear
side of the attachable stage into the two pin
holes on the graduated stage surface, and clamp
the screw using a driver or a coin.
Attachable mechanical stage is equipped with
point counters, which are 0.2mm or 0.3mm in
pitch. These counters can be replaced by releas-
ing the head of the point counters by means of
a coin and removing the milled part of the
counters.
