PRODUCT USE AND CARE
1.
2.
3.
4.
Maintain the Microscope with care. Keep this product clean. A properly main-
tained tool is easier to use. Do not use damaged optical instruments. Tag
damaged instruments “Do not use” until repaired.
Check for misalignment or binding of moving parts, loose or broken parts,
and any other condition that may affect the Microscope’s operation.
If damaged, have the Microscope serviced before using.
Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one product may become hazard-
ous when used on another product.
The Microscope is a delicate, precise, optical instrument and should be
handled carefully and kept clean and dry to avoid damage. When not in
use, keep the Microscope covered with a dry, clean cloth. Dust and moisture
can damage the instrument.

7.
Do not touch the optical parts of the Microscope with your fingers. Doing so
may damage the lenses.
If necessary, clean the lenses with a soft, dry brush. Do not clean with
moist cleaning agents.
Because the Microscope is a complex device, any repair and adjustments
should be performed only by a qualified service technician.
SERVICE
1.
When servicing the Microscope, use only identical replacement parts.
Follow instructions in the “Inspection, Maintenance, And Cleaning” section of this
manual. Use of unauthorized parts or failure to follow maintenance instructions

PRODUCT FEATURES
Parts Of The Microscope:
1.
2.
3.
Objective Lens: The Objective Lens (5) gathers light from the specimen. This
Microscope has interchangeable Objective Lenses. By changing the Objective
Lenses (going from relatively flat, low-magnification to rounder, high-magnifica-
tion), this Microscope can bring increasingly smaller areas into view.
(See Assy. Diagram.)
Drawtube & Zoom Eyepiece: The Drawtube (1) keeps the Eyepiece (1) at the
proper distance from the Objective Lens (5) and blocks out stray light. The
Zoom Eyepiece transmits and magnifies the image from the Objective Lens to
your eye. The Zoom Eyepiece is also used to make fine adjustments to focus
the image. (See Assy. Diagram.)
Turret: The Turret (4) is the rotating mount that holds the Objective Lenses (5).
(See Assy. Diagram.)
4.
5.
Hand Wheel: The Hand Wheel (11) is used to bring the specimen into the
focal plane of the Objective Lens (5). (See Assy. Diagram.)
Clip: The Clip (6) is used to hold the Slide (7) containing the specimen in posi-
tion on the Specimen Stage (8). (See Assy. Diagram.)
6.
7.
Drawtube Holder: The Drawtube Holder (2) is the curved portion of the Micro-
scope that holds all of the optical parts at a fixed distance and aligns them.
(See Assy. Diagram.)
Mirror: The Mirror (10) reflects light rays up through the Diaphragm (9) to the
specimen through a hole in the Specimen Stage (8). (See Assy. Diagram.)

8.
9.
Diaphragm: The Diaphragm (9) is placed in the light path to alter the amount of
light that reaches the condenser within the Microscope (for enhancing contrast in
the image). (See Assy. Diagram.)
Base: The Base (12) supports the weight of all of the Microscope parts.
(See Assy. Diagram.)
Specimen Preparation:
1.
When observing a specimen by transmitted light, light must pass through the
specimen in order to form an image. The thicker the specimen, the less light
passes through. The less light that passes through, the darker the image.
2.
3.
The specimens must be thin (0.1 to 0.5mm).
Many specimens must be cut into thin sections before observation. Specimens
such as rock or semiconductors are too thick to be sectioned and observed by
transmitted light, so they are observed by the light reflected from their surfaces.
MicroscopicTerms:
1.
Depth of Field: The vertical distance, from above to below the focal plane, that
yields an acceptable image.
2.
Field of View: The area of the specimen that can be seen through the Micro-
scope with a given Objective Lens (5).
3.
4.
Focal Length: The distance required for an Objective Lens (5) to bring the light
to a focus (usually measured in microns).
Focal Point/Focus: The point at which the light from an Objective Lens (5)
comes together.
5.
Magnification: The product of the magnifying powers of the Objective Lenses
(5) and Zoom Eyepiece (1). The numbers marked on the Objective Lenses
indicates how many times the specimen on the Slide (7) is being magnified. The
Objective Lenses on this Microscope allow a specimen to be magnified from
eight (8X) to twenty (20X) times its actual size.

OPERATING INSTRUCTIONS
1.
Always wear eye protection. Wear ANSI approved safety impact eye
glasses when using this product.
2.
3.
4.
Make sure the location in which you intend to use the Microscope is well lit.
Thoroughly clean and dry the Slide (7). (See Assy. Diagram.)
If necessary, section the specimen from 0.1 to 0.5mm thickness. Then, carefully
position the specimen in the middle of the Slide (7). (See Assy. Diagram.)
5.
6.
Center the Slide (7) on the Specimen Stage (8), and hold the Slide in place using
the Clip (6). (See Assy. Diagram.)
Turn the Turret (4) to align the 8X Objective Lens (5) directly over the specimen
to be observed. For greater magnification of the specimen, align the 20X Objec-
tive Lens over the specimen. (See Assy. Diagram.)
7.
8.
9.
While viewing into the Drawtube & Zoom Eyepiece (1), slowly turn the mecha-
nism clockwise or counterclockwise to bring the specimen image into focus.
(See Assy. Diagram.)
When finished viewing the specimen, move the Clip (6) off the Slide (7). Re-
move the Slide from the Microscope. Properly dispose of or store the specimen.
Then, thoroughly clean and dry the Slide. (See Assy. Diagram.)
Make sure to store the Microscope in a clean, dry, safe location out of reach
of unauthorized people.
INSPECTION, MAINTENANCE, AND CLEANING
1.
2.
Before each use, inspect the general condition of the Microscope. Check for
cracked, worn or damaged parts, and any other condition that may affect the
tool’s safe operation. If a problem occurs, have the problem corrected before
further use.
Do not use damaged equipment.
To clean, use a damp cloth and a mild detergent. Then dry. Do not use sol-
vents as damage to the Microscope will occur. Do not immerse the Micro-
scope in any liquid.
3.
4.
When storing, keep the Microscope in a clean, dry, safe location out of reach of
children.
CAUTION! All maintenance, service, and repairs not discussed in this
manual should only be performed by a qualified service technician.
