Optika stereo-microscope SZM
1. Introduction
The Ryeco zoom stereo microscopes SMZ series are high performance Greenough stereo microscopes with continuous
zoom system O,7:4.5 Total magnification varies from 1.75x to 180x depending on the eyepieces and auxiliary objectives used.
It is the best equipment lo examine all types of gross material s in three dimensions for industrial, biological and educational
applications.
With the bilateral zoom knob, the user can change the magnification in a factor of 6,428 with predict parfocality (focus is
always maintained during the change of magnification) and par centering (magnification changes in a concentric pattern).
There are different models in the series:
•Binocular head, basic stand with focus and integrated incident light / transmitted light
•Trinocular head, basic stand with focus and integrated incident light / transmitted light
•Binocular head, professional stand with focus and attached Ryf high frequency NKL18 Ring Illuminator
•Trinocular head, professional stand with focus and attached Ryf high frequency NKL18 Ring Illuminator
All the above versions may be fitted with a low cost overhanging universal Optika boom stand (Base Ø250mm/ stand height
480mm) or with the professional Ryf RUS-1 or RUS-2 Universal Stand (table clamp or 25 kg cast base plate (Swiss made)

2. Unpacking and Assembling of the Microscope
Unpacking the Microscope
The components for the SZM series stereo microscopes are shipped detached for protection. Open the Styrofoam packing with care
and do not leave any components attached to the packing being removed. Do not discard any of the packing materials
until all components have been located. lf damage occurs during transit, contact both the carrier and your supplier immediately.
Assembling the Microscope
•When handling the components, especially all the optical parts, avoid touching any lens surface with naked hand or
fingers. Any fingerprints or grease stains will negatively affect the image quality.
•After unpacking the stand, put it on a good stable table. Loosen the lock screw of the focusing carrier, adjust the height of
the focusing carrier and lock the lock screw again. Make sure that the support collar is secured firmly below the focusing
carrier along the vertical post. This is important as this collar functions to avoid the accidental falling of the microscope
along the column.
•The focusing carrier should rest on the support collar and both the focusing carrier lock screw and the lock screw of the
collar should be tightened.
•Put the stereo-body onto the focusing carrier and lock it by the lock screw on the right hand side of the focusing carrier. To
maintain the best stability, it is advisable e to lock the screw on the left hand side oft he focusing carrier.
•After removing the wrapping papers End packing materials around the eyepieces and other optical parts (avoid touching
the lens surface), carefully place the eyepieces into the eyepiece tubes.
3. Alignment and 0peration of the Stereomicroscope
Interpupillary Distance:
•Move the two eyepiece tubes until only one circular field can be seen through the two eyepieces. lf two circles appear,
the interpupillary distance is too big, and if 2 overlapped circles appear, the interpupillary distance is too small.
Focusing the Stereomicroscope:
•Try to focus the sample at the highest magnification with the focusing knob. lf it cannot be done, adjust the height of the
microscope along the vertical post. Remember to lock the lock screw and support collar after aligning the height of the
microscope.
•Turn the zoom to the highest magnification. By turning the focusing knob, focus the sample until the mage is clear a and
sharp.
•Turn the zoom down to the lowest magnification Adjust the diopter focusing knob oft the right eyepiece until the image of
the right eyepiece is clear and sharp.
•Repeat the procedure far the left eyepiece. Then, check the focus of the image for the whole zoom range. It should now
be perfectly parfocal .
Magnification and Working Distance:
•Select the desired magnification by adjusting the zoom knob. Change the eyepieces and,/or add an appropriate
magnifying objective lens if necessary.
•Total magnification used can be calculated by the following equation: Total magnification = Eyepiece magnification x
Zoom magnification x objective lens magnification
•Normal working distance for the standard configuration [1x objective lens] is 95mm.
Changing the bulb
•Before changing the bulb, make sure that the power switch is off and the power cord has been disconnected from the
220V main supply!
•For Incident light, unscrew the lamp collector piece out, remove the old light bulb from the socket and carefully plug the
new bulb in, screw the collector piece back after. changing the bulb.
•For the transmitted light, remove the stage glass plate by pushing down its rear side, remove the old bulb from the
socket and carefully plug the new bulb in.
•Never touch the glass surface of the bulb with naked hand, any grease stain brought onto the bulb by the naked hand
will negatively affect the life span of the bulb. Clean the bulb surface with alcohol or Ryf cleaning solvent and tissue if the
user has touched the bulb surface accidentally.

4. Knowing your Microscope
Stereo Body with Binocular or Trinocular Head:
For the SZM series stereomicroscopes, the binocular or trinocular tube is built together
with the stereo body to form a single piece named "stereo head”.
Stereo body
•The Stereo body is the key part of the microscope which includes the Greenough stereo zoom system 0,7:4,5. This
system includes two telescopic zoom optics working for the left and the right eyepiece tube separately.
•With this system, the user can enjoy excellent depth of field and stereo effect. With the help of the precision optics from
Ryeco, perfect parfocality can be maintained throughout the whole zoom range.
•Zoom knob is located bilaterally on both sides of the microscope and is printed with scale showing the zoom
magnification used. Adjust this knob for changing the magnification of the image. lf the microscope is properly aligned,
the image focus should always be maintained when zoom magnification is changed (parfocal). For alignment procedure,
please refer to section 3 of this manual.
•The stereo body is mounted onto the circular mount of the focusing carrier, and is locked by the lock screw on the left
hand side of the carrier. During the operation of the microscope, this lock screw should always be locked to maintain
utmost stability.
Binocular tube
The interpupillary distance can be adjusted by turning the two eyepiece tubes. For proper alignment of the interpupillary distance,
please refer to section no. 3 of the manual.
Trinocular / Beam Splitter tube for SZM:
•Concerning the interpupillary distance adjustment and eyepiece lock see above Binocular tube
•By pulling out the slider at the back of the trinocular tube, all the light from the right eyepiece tube will be deflected into
the phototube for TV or photography. At the same time, no light will enter into the right eyepiece tube for observation.
•At the top of the trinocular tube you can find the photo,/video attachment. With specific adaptor is possible the
connection with CCD camera, photo,/camera reflex (Digital Nikon or conventional) or a Nikon Coolpix
Stand
•Focusing carrier comes with the stand.
•To focus the sample, focusing knob is located bilaterally on both sides of the focusing carrier By turning this knob, the
microscope can be moved up or down for a certain distance to focus the sample. This movement is brought about by
the Pinion Rack mechanism. The tension of the focusing knob can be adjusted by rotating the right focusing knob
keeping still the left focusing knob.
Eyepieces and Auxiliary objectives:
•There are eyepieces of different magnifications for choices including lox, l5x and 2Ox. The standard equipment goes
with a pair of l0x eyepieces.
•To change the eyepieces, remove the original eyepieces, replace the new pair of eyepieces.
•There are additional objectives of different magnifications for choices including 0,5x, 1 ,5x, and 2x. We recommend to
use additional objectives depending on the requirements of the working distance and magnification.
•To add an additional objective (auxiliary lens) onto the microscope, the user can simply screw the additional objective
onto the stereo- head. The height of the microscope has to be readjusted as the working distance is changed when
additional lenses are used.
Other Accessories:
For SZM series there are other accessories designed to serve different specials applications:
Darkfield condenser
It has to be used with transmitted light. By putting this accessory onto the transmitted light outlet (with the frosted glass or stage
plate removed, it creates the darkfield effect. It works only with the transmitted light stand.
It is especially useful in jewelry or gem study and special techniques in Bio-Med applications including "ln “silver gain staining"
and embryo observation.
Photo Adapter:
With this accessory fitting onto the trinocular head, Digital cameras from Nikon (ask Ryf AG for more Details). The T-2 adapter
can be obtained from any photo-shop in your region or direct from Ryeco.
TV-Adapter C-mount:
With this accessory fitting onto the trinocular head, CCTV can be screwed into the trinocular tube for TV observation c-mount
or Cs-mount should be used depending on the CCD camera (ask Ryf AG for more Details).

6. Cleaning and care of the microscope
Changing the bulb
Before changing the bulb, make sure that the power switch is off and the Power cord has been disconnected
from the main supply.
For Incident light, unscrew the lamp collector piece out, remove the old light bulb from the socket, and carefully
plug the new bulb in, screw the collector piece back after changing the bulb.
For transmitted light, remove the stage glass plate by pushing down its rear side, and move the old bulb from the
socket and carefully plug the new bulb in.
Never touch the glass surface of the bulb with naked hand, any grease stain brought onto the bulb by the naked
hand will negatively affect the heat dissipation, and thus, greatly shorten the life span of the bulb. Clean the bulb
surface with Ryf Lens Cleaner or alcohol and tissue if the user has touched the bulb surface accidentally.
Cleaning
lf dust is found on the optical surface, try to remove by air blower or better with canned air (Ryf cleaning Set).
For fingerprint, grease stain or dust which cannot be removed by the air blower possible methods are
recommended:
•To breathe lightly on the glass surface and wipe with a clean piece of cloth, lens paper or cotton swab.
•Please notice that small cotton fiber may be left onto the lens surface if cotton swab is used.
•Use a cotton swab or lens paper dip with a small amount of absolute alcohol (or better with Ryf cleaning
Set) and clean the lens surface carefully. No other aggressive solvents should be used.
•In no circumstances should the user clean any lens surface with dry cotton swab, cloth or lens paper.
This will scratch the lens surface causing irreparable damage.
•Water is not recommended fop cleaning of lens as it will leave some water stain on the lens surface and
if water residue is left on the lens, fungus can grow causing irreparable damage.
