Focusing

The focusing kobs (6) are used to bring the image of the object into focus.

Adjusting the magnification

The Stereo Microscope has 2 achromatic zoom lenses. The magnification is continuously adjusted by turning the zoom adjustment knob (4).

Preparing the Stereo Microscope for use

Remove the microscope from its packaging and place it on a stable table. Make sure that the horizontal arm (10) is only pulled out to the extent that the stereo microscope

always stands securely and cannot tip over. Then slide the eyecups over the eyepieces. Now sit comfortably in front of the microscope and look through the eyepieces (1).

Working with the Stereo Microscope

• Set the focus (6) to a neutral position (carriage in mid-position and not at the stop).

• Place an object on the work surface and adjust the vertical position of the horizontal arm (10) until you see a reasonably sharp image,

then fix the vertical position of the horizontal arm (10) with the locking knob (14).

• Move the dioptre correction (2) to the neutral position (marking groove on the tube).

• Adjust the pupil distance by moving the prism housings (3) towards or away from each other until you see only a round image with both eyes.

Adjusting the eyepieces to get a sharp image over the entire zoom range

• Set the magnification to the largest value using the zoom knobs (4). Now focus on a specimen that is as flat as possible (e.g. a text).

• Set the magnification to the smallest value.

• Now correct the sharpness of the left eye by closing the right eye and adjusting the dioptre correction (2).

Do the same with the right eye.

Maintenance and cleaning

Always cover the microscope with a dust cover after use. Keep the eyepieces mounted in the microscope tube at all times, to prevent dust from getting into the device.

Cleaning the optics

If the lenses of the eyepiece are dirty, they can be wiped with a piece of lens paper (circular movements). If this does not bring an improvement, moisten the lens paper with a

drop of xylene or alcohol. Never apply xylene or alcohol directly on the lenses!
If dirt is clearly visible in the field of view, this is located on the lowest lens of the eyepiece. The eyepiece can simply be pulled out of the tube. Now clean the outside of the

lens. If dust is still visible, make certain that the dust is really in the eyepiece by rotating the eyepiece. If this is definitely the case, carefully unscrew the bottom lens from the

housing and clean it.

Warning:

Cloths with plastic fibres can damage the coating of the lenses!

Cleaning the stand

Dust can be removed with a brush. If the stand is very dirty, the surface can be cleaned with a non-aggressive cleaning agent.
