Zoology Lesson 1 Microscope

Question 1

It uses a set of lenses also known as lens systems

Answer 1

COMPOUND

Question 2

It uses a single lens

Answer 2

SIMPLE

Question 3

Houses the optical parts in the upper part of the
microscope

Answer 3

HEAD/BODY

Question 4

Supports the microscope and houses
the illuminator

Answer 4

BASE

Question 5

Connects to the base and supports the microscope head. It is also used to carry the microscope

Answer 5

ARM

Question 6

Two optical system used in compound microscope

Answer 6

Eyepiece Lenses and Objective Lenses

Question 7

is what you look through at the top of the microscope.

Answer 7

EYEPIECE OR OCULAR

Question 8

holds the eyepieces in place above the objective lens.

Answer 8

EYEPIECE TUBE

Question 9

are the primary optical lenses on a microscope. They range from 4x-100x and typically, include, three, four or five on lens on most microscopes.

Answer 9

OBJECTIVE LENSES

Question 10

Houses the objective lenses

Answer 10

NOSEPIECE

Question 11

are used to focus the microscope. Increasingly, they are coaxial knobs - that is to say they are built on the same axis with the fine focus knob on the outside.

Answer 11

COURSE AND FINE FOCUS KNOBS

Question 12

is where the specimen to be viewed is placed.

Answer 12

STAGE

Question 13

are used when there is no mechanical stage. The
viewer is required to move the slide manually to view different sections of the specimen.

Answer 13

STAGE CLIPS

Question 14

is the hole in the stage through which the base (transmitted) light reaches the stage.

Answer 14

APERTURE

Question 15

is the light source for a microscope, typically located in the
base of the microscope.

Answer 15

ILLUMINATOR

Question 16

is used to collect and focus the light from the illuminator on
to the specimen. It is located under the stage often in
conjunction with an iris diaphragm.

Answer 16

CONDENSER

Question 17

is the light source for a microscope, typically located in the base of the microscope. Most light microscopes use low
voltage, halogen bulbs with continuous variable lighting
control located within the base.

Answer 17

IRIS DIAPHRAGM

Question 18

moves the condenser up or down to control the lighting
focus on the specimen.

Answer 18

CONDENSER FOCUS KNOB
