Getting Started
This user guide is written on the assumption that it will be used by advanced
students and experienced microscopists. It covers the essential adjustments and
controls of VWR VistaVision microscopes. No attempt has been made to
include fundamentals of microscopy. Read this user guide prior to unpacking
the microscope. After assembling the instrument, re-read the manual and
become familiar with all adjustments and functions before using your new
microscope.

Basic Operation
1. Illumination Controls
1) The power switch to the
illuminator and the brightness
control are located on the base. The
electrical system is fuse protected
and the fuse holder located on the
bottom of frame.
2) Turn on the light with the power
switch, see Figure 4. If the light
does not appear to be ON, check
the brightness control to see if it’s on a sufficiently low setting.
2. Focusing Controls
1) Focusing adjustment is
accomplished by using the large
coarse adjustment knobs located
comfortably on each side of the
frame. Fine adjustment is
accomplished by using the smaller
knobs located on the same focus
shaft. This coaxial arrangement
allows for easy, precise adjustment
without drift or discomfort.
2) Focus Control Turning either of
the coarse focus control knobs will
raise or lower the stage. The
smallest graduation on the fine
adjust knob index scale is 2μm of vertical.
3) Focus Tension Adjustment The tension of the coarse focus is
adjustable and preset at the factory for ease of use. If you wish to
adjust the coarse focus tension, turning the ring toward the rear of the
Brightness Control

microscope increases the tension, and toward the front of the
microscope loosens it. Tension is too high if you experience physical
discomfort
4) Pre-focusing or Focus Stop Control Use of this feature will insure
that the longer objectives don’t contact the stage or specimen when
using the microscope. Its use also simplifies focusing. After focusing
on the specimen with the coarse adjustment, rotation of the lever
toward the front of the microscope will set an upper limit on the coarse
adjustment movement. After changing specimens or objectives,
focusing is easily accomplished by rotating the coarse adjustment knob
to reach the pre-focused position, then making fine adjustments with
the fine adjustment knob. Focusing movement with the fine adjustment
knob isn’t affected by using the pre-focusing lever
3. Interpupillary and DiopterAdjustments
1) Diopter Adjustment Proper
correction for individual vision is
accomplished via the diopter
adjustment located at the left
eyepiece, see Figure 6. Using the
40X objective, close your left eye
and bring an image into focus with
your right eye only. Once the
image is well focused, make fine adjustments with the diopter
adjustment ring to correct for your vision.
2) Proper interpupillary distance, or the distance between eyepieces, is
crucial to the comfort of the user. Adjusting the interpupillary distance
is accomplished through a “folding” action of the optical head, at
Figure 6, allowing for quick and easy adjustment
4. Mechanical Stage Controls – The mechanical stage, see Figure 7, with
Ultra-Low position control knobs for ease of use, consists of three parts:
1) The smaller knob for transverse adjustment
Figure 6
Diopter Adjustment Ring

2) The larger knob for longitudinal
adjustment
3) The slide holder. When using the
slide holder, first lower the stage,
then push the spring loaded chrome
handle towards the rear and push
the slide into position, then gently
release the handle, securing the
slide into position.
Note: the slide holder can be easily
removed by loosening the two
thumbscrews, then sliding the holder
toward the front to disengage.
5. Condenser Components – are
located below the stage as follows, see
Figure 8: Abbe condenser; its
Mounting Ring with lock screw and
two large centering screws at either
side for adjusting condenser/iris
assembly in the optical center of the
light path; the adjustment knob for
raising and lowering the condenser.
Below the Abbe Condenser is a
circular filter tray to hold the filters.
6. CondenserAlignment – to center theAbbe Condenser in the optical light
path, see Figure 8:
1) Close the Condenser Iris Diaphragm
2) Observe the image using the 4X objective and you will see an image
similar to Figure 9 A. The image may be out of focus and out of center

3) To center the iris opening in the
field of view, use the two centering
screws at each side of the Abbe
Condenser mounting ring, see
Figure 9 B.
4) To focus the iris opening, adjust
the coarse focus and the Abbe Adjustment Knob until the image is as
crisp as possible against the darker field of view.
5) Once the image is in focus and centered in the field of view, open the
Condenser Iris Diaphragm until the image is almost as large as the
field of view, see Figure 9 C.
Changing The Light Bulb
1. Disconnect the power plug and wait
to be sure the bulb is cool. On the
bottom of the frame there is a hinged
door for replacing the lamp bulb. The
lamp door retaining screw is to the
front of the frame, and the lamp
centering screw is located in the
middle of the lamp door. Open the
lamp door using the lamp door
retaining screw as shown in Figure 10.
2. Pull the old lamp straight out of the
socket. Always use a clean cloth or
lens tissue to prevent grease or oil
getting on the glass of the new bulb. Insert the lamp pins straight into the
socket. Close the lamp door and center the lamp in the field of view using
the lamp centering screw at the center of the lamp door, see Figure 10.

Preventative Maintenance
1. Cleaning frame and stage
Disconnect the plug from mains socket before cleaning. Clean the frame
and stage with a soft cloth moistened with a mild detergent solution. Be
sure the instrument is dry before using.
2. Cleaning optical parts
Microscope eyepieces and objectives are coated.
They should not be wiped while dry as dirt or dust may scratch the
coating. It is best to remove parts from the frame prior to cleaning.
Always blow loose dust away first. Use cotton swabs or lens tissue
moistened with a lens cleaner or a small amount of alcohol, then wipe the
surface clean with a good quality lens tissue. Solvents such as Xylene
should NOT be used as cleaner.
3. Cleaning 100X oil immersion lens
The immersion oil should be removed from the lens at the end of each
workday using cotton swabs or lens tissue moistened with a lens cleaner
or a small amount of alcohol.
DO NOT DISASSEMBLE OBJECTIVE LENSES.
