#631-0125 Stereo Zoom Microscope

APPLICATIONS:

Widely used in electronics industry, assembling and inspection of
precise instruments and meters, educational experiments, observation
and research. It can be used in the schools, research institutes, factories,
and families to study the geology, out appearance of objects.

MAJOR TECHNICAL INDEX:

1. Optical index(mm)
Field of view
Working distance
Zooming objective
Auxiliary objective
2. Electric index:
Input voltage: 220V/50Hz or 110V/60Hz (Optional)
The below 4 illumination styles are optional:
• Incident light of bowl shaped halogen lamp 12V/10W, transmitted
illuminator is the same as the incident
• Incident light of bowl shaped halogen lamp 12V/10W, transmitted
illuminator is the same as the incident with dimmer
• Incident illuminator 12V/10W, transmitted illuminator 5W fluorescent lamp.
• Incident illuminator 12V/10W, transmitted illuminator 5W fluorescent lamp with dimmer
3. Structure index:
Slanting 45 degree binocular head of 360 degrees rotatable. Left and right eyepiece diopter adjustment +/- 5
degrees , inter-pupillary distance adjustable 54—76mm . Optional auxiliary objective (M48x0.75)

HOW TO USE:

1) Environment requirement: Dry dust free room temperature between –5---+40 degrees Celsius.
2) Illuminator control: Plug in the power cord into the outlet. Refer to the following table for illumination styles.
For microscopes with dimmer control the brightness of the illuminators can be adjusted.
3) Select the stage:
1. The frost glass stage is placed on the base and is fixed with a screw, It is used when a transparent specimen
is being observed, please use transmitted illuminator.
2. Black and white stage is kept in the packing as an accessory. When it is to be used take off the glass stage
and place the black and white stage on the base. Normally the white side is upward. If the specimen is
white or in other bright colors, use the black side to improve the contrast with only incident illuminator.
4) Placement of specimen:
Place the clean specimen in the center of the stage and fix it with clippers if necessary.
5) Use of rubber eye-guard: One pair of rubber eye guards is contained in the packing. They are used to prevent
the extra light from entering the eyepieces, to improve visibility.
