Levenhuk ZOOM Series Stereo Microscopes
General Information
Levenhuk ZOOM Series stereo microscopes are safe regarding the health, life, and property of consumers and the environment
when properly used. Thanks to the contrast image, depth of focus, and high resolution, they are widely used in the agriculture,
jewelry, and electronic industries, for studying and working with precise mechanisms, etc. Great for studying volumetric
opaque objects in the natural science and engineering fields, Levenhuk ZOOM Series Microscopes can also be a common tool for
education and research. This series meets the requirements of the international standards.
The kit includes:
• microscope stand and base
• eyepiece head: binocular (ZOOM 1B), trinocular (ZOOM 1T)
• objectives: 0.7—4.5x
• pair of eyepieces: WF10x/22
• power cable
• pair of eyecups
• fuse
• dust cover
• user manual and lifetime warranty
Microscope parts
Base. It supports the weight of the microscope, and houses the illumination source, electronics and control mechanisms.
Arm. This piece holds the base and the head of the microscope together.
Eyepiece head. A binocular (ZOOM 1B) or trinocular (ZOOM 1T) eyepiece head is mounted at the upper end of the arm.
Eyepieces and objective. Consist of lenses that allow magnifying the image. The total magnification is calculated by multiplying
the eyepiece magnification to the objective magnification.
Magnification adjustment knob. Turn this knob to adjust the magnification of the image.
Stage. Sturdy and reliable stage with clips to place and fix the specimen for further examination.
Focusing knob. A coarse focusing system allows for moving the stage up and down for adjusting the sharpness.
Illumination. The upper and lower LEDs are used to illuminate the observed samples. The illumination system can be powered
by A/C.
Using the microscope
Stage inset glass
• Frosted glass stage inset may be used for observations of transparent specimens or thin slices of objects. Place it on the
stage and secure it in place with the locking screw. Lower illumination source should be used during observations with this
glass stage inset.
• The kit of your new microscope may also include a black and white glass stage inset. Normally, you would want to use the
white side; however, if a specimen is very bright, or colored white, you should use the black side for additional contrast.
Upper illumination source should be used during observations with this glass stage inset. Before installing the black and
white glass make sure to remove the frosted glass from the stage.
Getting started
• Unpack the microscope and make sure all parts are available.
• Move the eyepiece head to the lowermost position using the focusing knob.
• Connect the microscope to A/C power using the A/C adapter.
• Turn on the illumination with the illumination switch.
• Select the desired magnification using the magnification adjustment knob.
• Slowly adjust the illumination brightness using the brightness adjustment wheel. When you finish your observations, always
dim the illumination before unplugging the power cable.
• If you need to change the light bulb, unplug your microscope first.
Eyecups
For additional comfort during observations you can use rubber eyecups on both eyepieces.
Focusing, diopter adjustment, interpupillary distance
Place a slide on the stage and lock it in place with stage clips. Loosen the locking knob on the microscope pole and slide the
eyepiece head up or down into the desired position and tighten the locking knob. Afterwards, turn the focus knob until the
image is sharp and clear. Look through the left eyepiece and rotate the diopter adjustment ring until the image is sharp and
clear. Do not adjust focus during diopter adjustment! Upon completing this process, look through both eyepieces, hold them
with your hands and bring them closer or move them apart until a double image turns into a single image.
Changing objective lenses
Levenhuk ZOOM Series stereo microscopes are equipped with a revolving nosepiece with one objective lens variable multiplicity.
To change the magnification, turn the magnification adjustment knob.
