MICROSCOPE PARTS & FX

Question 1

Magnifies the image formed by the objective lens, usually 10x or 15x magnification.

Answer 1

Eyepiece (Ocular Lens)

Question 2

Magnify the specimen at different levels, commonly 4x (scanning), 10x (low power), 40x (high power), and 100x (oil immersion).

Answer 2

Objective Lenses

Question 3

Holds and rotates the objective lenses, allowing the user to switch between magnifications.

Answer 3

Nosepiece (Revolving Turret)

Question 4

The flat platform where the slides with specimens are placed for viewing.

Answer 4

Stage

Question 5

Secure the slide in place on the stage for stability.

Answer 5

Stage Clips

Question 6

Allows precise movement of the slide using control knobs for X and Y axis movements.

Answer 6

Mechanical Stage

Question 7

Moves the stage up and down for general focus, particularly at low magnifications.

Answer 7

Coarse Adjustment Knob

Question 8

Provides fine-tuning for sharp focus, especially at higher magnifications.

Answer 8

Fine Adjustment Knob

Question 9

Focuses light from the illuminator onto the specimen for better clarity and resolution.

Answer 9

Condenser

Question 10

Regulates the amount of light reaching the specimen to control contrast and resolution.

Answer 10

Diaphragm (Iris Diaphragm)

Question 11

The hole in the stage through which light is passed to illuminate the specimen. Its size affects how much light is allowed through.

Answer 11

Aperture

Question 12

Provides illumination for viewing the specimen, usually a built-in light or a mirror to reflect external light.

Answer 12

Light Source (Illuminator)

Question 13

Turns the light source on and off for illumination control.

Answer 13

Light Switch

Question 14

Adjusts the intensity of the light source for optimal visibility depending on the specimen and magnification.

Answer 14

Brightness Adjustment Knob

Question 15

Connects the base to the upper part of the microscope and is used for carrying the microscope.

Answer 15

Arm

Question 16

Provides stability and support for the entire microscope structure.

Answer 16

Base

Question 17

Allows for precise movement of the slide horizontally (X axis) and vertically (Y axis) while viewing the specimen.

Answer 17

Stage Control (X-Y Control)

Question 18

Adjusts the focus on the eyepiece(s) to compensate for differences in vision between the user’s eyes.

Answer 18

Diopter Adjustment

Question 19

The space between the objective lenses and the stage

Answer 19

“working distance” or “focal distance”
