MICROSCOPE COMPONENTS:
1. Ocular Barrel—a protective cover is provided for the ocular barrel. This should be removed
before use.
2. Focusing knob—This knob is twisted to adjust the distance between the slide and the lens
in order to bring the object being viewed into focus.
3. Connection barrel—This connects the ocular barrel to the multiple objective lens holder.
4. Objective lens holder—This holder contains 3 objective lenses of varying magnifying power.
The objective lenses can be changed by rotating the disc until a click is heard indicating that
the lens is locked in place.
5. Objective lenses—There are 3 objective lenses to choose from. 75x, 300x, 900x
6. Vertical arm
7. Slide support—to support the specimen being studied.
8. Slide clip—used to support the specimen being studied.
9. Spotlight—Used to light specimen when there is not enough natural light available. The
light is switched on when the unit is turned over so that the bulb points upward (A). If the
bulb needs replacing, push the white collar downwards and twist it through 90 degrees
counterclockwise (B). The bulb and its holder can then be removed. To install a new bulb,
align two notches on the bulb seat, push downward, and twist is slightly clockwise (C). Then
it is positioned.
10. Reflector—Used to reflect natural light onto specimen (D).
11. Base
12. Anti-slip base—The spotlight is powered by 2xAA type batteries. The bottom base can be
pulled off to allow access to the battery box inside the base of the microscope (E).
