INTRODUCTION
Ryeco Stereomicroscopes series RST20 and RST30 7 RST40 are good quality stereomicroscopes with
different objectives. These stereomicroscopes are the good choose for primary and secondary class
teaching (Swiss Standard).
Unpacking and assembling of the microscope
The components for series stereo Ryeco RST 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.
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 f 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.
Magnification
Select the desired magnification (when possible…) by adjusting the rotary objective revolver.
