Exchanging Objective Nosepiece, Photomicrography

d o w n w a r d, turn the rinn of th e stage counterclockwise . Fastening of th e floating stage is necessary, when using an attachable mechanical stage (Fig. 22), which will be avail- able on order.

The circular rotating stage type G is also available, which

2 2 permits measurement of th e rotating angle o f specimen with its circular scale. (Fig. 23) .

EXCHANGING THE

OBJECTIVE NOSEPIECE

It may become necessary to exchange the objective nosepiece in such a case when a series of phase - contrast or metallurgical objectives are mounted as a unit on the other objective nosepiece.

First, unlock the revolver lock screw, and draw out the nosepiece in the direction of the arrow (Fig . 24). In place, in- sert th e other nosepiece gently until it stops, making the guid- ing surfaces of the dove-tail fit parallel to each other.

Fasten the revolver in position by means of the lock screw

(Fig. 25).

PHOTOMICROGRAPHY

The Microscope Model L-Ke, incorporating the Koehler illumination device with light source built in the microscope base, enables convenient and perfect microphotograph only by additionally m o u n t i n g a camera connected to the microscope eyepiece with any photomicrographic adapter.

Therefore, when taking photographs of th e microscopic image on 3 5 m m f i l m , it is recommended to use the Nikon Microflex Model EFM (with built-in exposure meter) or AFM (with built-in exposure meter permitting automatic exposure setting) and th e Nikon F or Nikkormat camera or Nikon Dark Box for using with th e above attachments . For details of photomicrographic methods, refer to the " I n s t r u c t i o n s of Using Nikon Microflex E F M " or " A F M " and any general works on photomicrography .
