IMPORTANT FEATURES
ACCU-SCOPE’S Stereomicroscopes have fixed magnification systems. Total magnification power is the
product of objective magnification multiplied by the eyepiece magnification:

Inclined eyepiece tubes allow for interpupillary distance of 55mm to 75mm and diopter adjustment of ±5.
Working distance is 57mm. ACCU-SCOPE’S Stereomicroscopes feature a two-way illumination system
which may be used to provide transmitted light or reflected light. Your Stereomicroscope comes
completely assembled and ready for use. Simply follow the step-by step operating procedure outlined in
section 5.0 for years of use from your stereomicroscope.

MAGNIFICATION SYSTEM
Each microscope in the 3050 Stereomicroscope series has two objectives. The rotatable turret housing the
two objectives allows the user to easily change magnifications while the specimen remains in focus.
Additional magnification ranges can be obtained through the use of different eyepieces. Information,
product availability and pricing information is available from your authorized ACCU-SCOPE distributor.

ILLUMINATION SYSTEM
The 3050 Stereomicroscope series is equipped with a built-in, two way illuminator system. The convenient
on/off switch is located on the base of the instrument and controls both the incident and transmitted
illumination. The illumination system consists of a 12v 10w bulb from above and below.

OPERATING INSTRUCTIONS
Follow these simple instructions to begin using your Stereomicroscope:
1.
Your stereomicroscope should always be used on a hard, flat and stable surface.
2.
Plug the stereomicroscope power cord into a grounded electrical outlet. A grounded 3-wire
line cord is provided.
3.
Select the appropriate light switch for the specimen. There are two types of illumination:
-Incident Light (top) - to view opaque specimens.
-Transmitted Light (bottom) - to observe translucent specimens.
4.
Place a specimen on the stage plate area directly below the center of the stereomicroscope
body. While looking through the eyepieces with both eyes, slowly adjust the distance between
the eyepiece tubes until you see a complete circle of light at the same time without moving
your head. The eyepiece tubes are inclined at 45 degrees to maximize your viewing comfort.
5.
Focus the stereomicroscope at the highest power by turning the objective turret to the highest
magnification power and then use the large focusing knob to bring the specimen into focus.
Rotate the turret to the lower power, making focal corrections by rotating the diopter collar
off of the zero setting for proper focus. This will keep the specimen in close focus at any
magnification. A slight turn of the focus knob may be needed to sharpen the focus.
