Adjusting the magnification
The Stereo Zoom Microscope has 2 achromatic zoom lenses. The magnification is continuously adjusted by turning the rotary knobs for the zoom function.
Illumination
The stand has adjustable incident light and transmitted light LED illumination. The main switch is located on the right side of the stand base.
The two lights can be used simultaneously. The rotary controls for incident light and transmitted light are located on the right side of the stand base.
• LED: Incident light illumination
• LED: Transmitted light illumination
Preparing the Stereo Zoom Microscope for use
Remove the microscope from its packaging and place it on a stable table. Insert the mains plug into a power socket and operate the main switch. Then switch on the
illumination of the microscope. Then slide the eyecups over the eyepieces. Now sit comfortably in front of the microscope and look through the eyepieces.
Attention:
When using the black and white object plate, the transmitted light illumination must be switched off!
Working with the Stereo Microscope
• Set the focus to a neutral position.
• Place an object on the object plate and adjust the height of the stereo head until you see a reasonably sharp image and fix the head support with the locking
button on the rear side.
• Move the dioptre correction from both eyepieces into the neutral position (marking groove on the tube).
• Adjust the pupil distance by moving the prism housings towards or away from each other until you see 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 adjustment function. 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. 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.
