4.0 ALIgnMEnT And OPERATIOn Of ThE MICROSCOPE
Interpupillary distance
Move the two eyepiece tubes until only one circular field can be seen through the two eyepieces. If two cir-
cles appear the interpupillary distance is too big, if two overlapped circles appear the interpupillary distance
is too small.
focusing the microscope
Try to focus the sample with the magnification x by using the focusing knobs or, if necessary, adjust the hei-
ght of the microscope along the vertical stand.
Magnification
select the magnification (when it's possible) by adjusting the rotable objective. The total magnification can be
calculated by the following equation:
EYEPIECE MAgnIfICATIOn x OBjECTIVE LEnS MAgnIfICATIOn

5.0 KnOwIng YOuR MICROSCOPE

Stereo head
In the microscopes sT-0, sT-40, sT-45, the binocular tube is built together with the stereo body to form a sin-
gle piece named "stereo-head". stereo-head contains two optical systems that work separately for the right
and the left eyepiece. With this system, the user can obtain a great depth of view and a stereoscopic effect.
Stand, illuminator
The stand is equipped with an inox pole and the focusing mechanism (with stereo head) can be moved verti-
cally to obtain the right focusing.
The double illumination system of model sT-40-l allows to use two illuminators at the same time; use the
master switch and selector switch to turn one or both lights on.
The plate for the samples is provided with two clips that help to "block" in place the object. The plate is sup-
plied in two different versions: black/white (for incident light) and translucent glass (for transmitted light).
