Operating principle of the individual components
The Stereo Microscope consists of a stand base, a vertical stand column and a head with focusing device. Always hold the microscope by the stand when
you want to move it.
Tubes
The two tubes have a tilt angle of 45° and can be rotated by 360° if necessary.
Optical specifications
The Stereo Microscope has a pair of 10x wide field eyepieces and two pairs (non-interchangeable) of achromatic 2x and 4x lenses in a rotary lens revolver. The total
magnification of the microscope is calculated by multiplying the magnification of the eyepieces by the magnification of the lenses. The eyepieces are each fixed in the
tube with a small screw.
Object stage
The object stage has integrated transmitted light illumination, a transparent object plate and two object clamps. A black and white object plate is also provided.
Focusing
Focusing is used to bring the image of the object into focus. The working distance (distance between the underside of the lens and the top of the object) is approx. 75mm.
Lens revolver
Two pairs of achromatic lenses are integrated in the rotary lens revolver. A different magnification is set by rotating the lens revolver by 180°. T urn the lens revolver until
you hear a click.
Illumination
This model is equipped with LED incident light and transmitted light illumination
• LED: Incident light illumination
• LED: Transmitted light illumination
Both lights can be used simultaneously (switch for lighting).
Preparing the Stereo Microscope for use
Remove the microscope from its packaging and place it on a stable table. Insert the mains plug into a socket, press the main switch (POWER) and switch on the lighting
with the switch for lighting. Then slide the eyecups over the eyepieces. Now sit comfortably in front of the microscope and look through the eyepieces.
Working with the Stereo Microscope
Place an object on the object plate and set the ideal height for the object with the height adjustment mechanism on the stand column.
Then use the focusing mechanism to focus the image.
• Adjust the pupil distance by moving the prism housings towards or away from each other until you see a round image with both eyes.
• Normally, both eyepiece tubes should have the same length. T o adjust for any difference between the two eyes, please proceed as follows:
T ake a flat object and look into the right eyepiece with your right eye only. Now use the focusing mechanism to focus the image.
Now look through the left eyepiece with your left eye only and use the dioptre adjustment mechanism on the left tube to get a sharp image.
• The models with illumination also have a black and white object plate that is easy to replace. The black side can be used to observe objects that are
better displayed against a dark background.
Attention:
When using the black and white object plate, the transmitted light illumination must be switched off!
