I. Slide Cover Slips

J. Color Filter. Use this filter to add color and

enhance an image in the eyepiece.

K. Butterfly Specimen

L. Petri Dish

M. Brine Shrimp Hatchery

N. Eyedropper

O. Micro-slicer

P.

The Eyepiece with fixed lens that has a 10X

magnification. Remove the dust cover from

the eyepiece and put it aside in a safe place.

Q.

The Body Tube. Connected to the eyepiece

and helps focus the lenses.

R. Power Indicator/ Objective Turret. The tur-

ret has 3 lenses or objectives: 10X, 40X, and

90X (See

Fig. 2). The shorter the objective,

the lower the power or magnification. The

longest objective is the highest power. To

calculate the magnification you are using,

multiply the value of the objective by the

power of the eyepiece (note that the power

indicator on the turret makes this calculation

for you). For example, turn the power indi-

cator to the longest objective (90X), and

multiply by the power of your fixed eyepiece

(1OX) – you will magnify the object by 900

times (note that the power indicator reads

900). This means that the object appears

900 times larger than it appears to the naked

eye!

Gently turn the power indicator on the objec-

tive turret (

R, Fig. 1). You will feel and hear

the objectives lens click into place. Practice

turning the focus knob (

X, Fig. 1) in both

directions and notice how far you can turn it

without letting the objective come into con-

tact with the stage (S, Fig. 1).

S.

The Stage is a flat platform with a hole in the

center to allow reflected light off the mirror or

light source to enter the microscope.

TIP: Begin viewing

at the lowest mag-

nification or power

and focus the

object. Once the

image is focused,

increase magnifi-

cation by turning

the objective turret

and refocus.

CAUTION: Be

careful as you turn

the focus knob so

that the objective

lens does not

make contact with

a slide or the

stage. This may

cause damage to

the slide and also

to the objective

lens.
