INTRODUCTION
Ryeco Stereomicroscopes series STEREO, LAB10 and LAB20 are high level shool stereomicroscopes
with objectives 2x-4x (LAB10) or zoom 1x4x (LAB20). The magnification is from 5x to 12Ox by using
additional lens (optional).These stereomicroscopes are the good choose for the professional user.
Unpacking and assembling of the microscope
The components for series stereo Ryeco LAB10 and LAB20 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.
When handing 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 (see Ryf Cleaning Sets).
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.

Alignment and operation
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 microscope
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
image is clear and sharp.
Turn the zoom (or change the objective by rotation) down to the lowest magnification. Adjust the diopter
focusing knob of the right eyepiece until the mage of the right eyepiece s clear and sharp.
Magnification
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 Normal working distance for the
standard configuration is 90mm.
Knowing your microscope
For Ryeco LAB series stereomicroscope the
binocular is built together with the stereo body
to form a single piece named "Stereo-head'.
The Stereo body is the key part of the
microscope, which includes the Greenough
stereo-zoom system 1x4x or fix objective 2x and
4x. This system includes two telescopic zoom
optics working for the left and the right eyepiece
tube separately (3D = stereo view) .
With this system, the user can enjoy excellent
depth of field and stereo effect. With the help of
the precision optics from Ryf-Ryeco, perfect
parfocality can be maintained throughout the
whole zoom range.
Zoom knob in RAB-2 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
oft he image. if the microscope is properly
aligned, the image focus should always be
maintained when zoom magnification is
changed [parfocal].
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,
the Lock screw should always be locked to
maintain stability.

Cleaning and care of the microscope
Changing the bulb
Before changing the bulb, make sure that the power switch is off and the CH 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 may not 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 (better results with
Ryf special 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.
