-６-
(1) Adjustment of Condenser and Aperture diaphragm
1Rotate condenser focusing knob M to adjusting distance between condenser ⑤and specimen, will
change the uniform illumination to obtain the best brightness.
2Slide handle of iris aperture diaphragm D to change iris aperture’s size , will change the specimen’s
contrast. Narrow diaphragm , lower brightness and resolution, higher contrast and depth of field ;
widen diaphragm, higher brightness and resolution, lower contrast and depth of field. Numerical
aperture(N/A) is decided by iris aperture diaphragm . Illumination N/A is match with objective N/A,
can provide excellent resolution and contrast , increase depth of field.
Because the microscopic specimens usually has low contrast, so in use, recommend the condenser aperture
diaphragm set to objective numerical aperture’s 70% ~ 80%, when necessary, unload the eyepiece in direct
observations from eyepiece tube, readjust again.
Another in condenser ⑤,the D subscript corresponding scale with objective. According to the scale
position and D’s the basic line ,should be adjusted relatively.
▲If iris aperture diaphragm is too narrow, will get double image.

1Put 10× objective in optical path, anticlockwise rotate E, narrow the field diaphragm.
2Observation through eyepiece, rotate M to adjust condenser’s height , focusing on specimen’s surface.
Rotate condenser focusing knob until in the middle of the field.
3Put 40× Objective in optical path, rotate E will make field image slightly bigger than field. Please
readjust if field image isn’t in middle.
4.2 Use of Oil objective
This microscope with 100× objective can observe specimen without immersion oil. But little non-synthetic
resin immersion oil between the objective and specimens will fully grasp the objective function and
bubbles and impurities can’t in immersion oil which will affect image.
First pull out 40× objective after focusing, apply a drop of oil will then baptized into light objective 100×.
This should gently turning telescope converter or slightly rotation handle and mobile platform of small, at
the same time, slightly turn the handle, micro focus to exclude the bubbles, otherwise immersed will
seriously affect imaging results.
▲Immediately after observing with absorbent cotton, lens paper, gauze or soft cloth dips in with
industrial ethyl alcohol (proportion 1:4) to wipe the oil on instrument and slices.
▲Although immersion oil is non-toxic, please thoroughly flush with soap and water if touching skin,
such as thoroughly flush eyes with water for fifteen minutes, if the eye and skin appearance changes or
pain, please immediately go to the hospital.
