to rotate around axis of rotation,come to Y-direction movement,and keep head part of
microscope to swing on horizontal position.left-right movement to come to X-direction
swing.two-dimensional rotation are able to apply to brain and ENT surgery.
Foot switch can control focusing and zooming in succession or using the hand knob (7)
for continuous zooming manually. The operator can observe the zooming coefficient from
window (3).; The light source seat (13) offers high brightness coaxial illumination of cold light
source ; Oblique illumination

provide incline illumination,after change focus of lens and
then rotate Oblique facula adjusted knob to make facula both of oblique illumination and
coaxial illumination to be coincide.
On the top surface of the zooming body (14) there is a standard snap mouth that can
receive various types of microscopic lens and also to connect beam splitter. The both sides of
beam splitter can at the same time be connected with camera interface and CCD interface for
video recording, taking pictures and data storage. The standard snap mouth is fixed with
locking screw. The delivered microscope is provided with a 175mm (focal length) objective.
Optional objectives such as 200mm, 250mm, 300mm, 350mm and 400mm could be provided
in meeting with the need of operation based on customer’s request The front of the zooming
body (14) has one window (3) indicating current zooming index value. (Note: zooming index
is not the practical magnification power).
The assistant observing microscope (8) is a binocular coaxial zooming stereoscope. The
assistant microscope and the chief operator microscope form a 90° observing angle. The
assistant observing microscope are fixed at the right and left points 90
o
from the chief operator
microscope.
Note:There is a Facula modulation knob(6)on the back of seat of light source, By pulling the
macula protection knob (6) outside to come to insert small facula into the viewfield when it is
necessary to be small facula for ENT surgery or inspection.
