New cards

Head

also known as the body, it carries the optical parts in the upper part of the microscope.

2
New cards

Base

Acts as the microscope support

3
New cards

Arms

The part that connects the base to the head and the eyepiece tube to the microscope

4
New cards

Eyepiece

Also know as the ocular, and it is the part used to look through the microscope

5
New cards

Eyepiece tube

its the eyepiece holder. It carries the eyepiece just above the objective lens.

6
New cards

Objective lenses

These are the major lenses used for specimen visualization. They have a magnification power of 40x-100X.

7
New cards

Nose piece

also known as the revolving turret. It holds the objective Lenses.

8
New cards

Adjustment knobs

These are knobs that are used to focus the microscope.

9
New cards

Stage

section on which the specimen is placed for viewing.

10
New cards

Aperture

This is a hole on the microscope stage, through which thE transmitted light from the source reaches the stage.

11
New cards

Microscopic illuminator

microscopes light source

12
New cards

Condenser

lenses that are used to collect and focus light from the illuminator into the specimen.

13
New cards

Diaphragm

also known as the iris. Its found under the stage of the microscope and its primary role is to control the amount of light that reaches the specimen.

14
New cards

Condenser focus knob

this is a knob that moves the condenser up or down thus controlling the focus of light on the specimen.

15
New cards

Abbe Condenser

condenser specially designed on high-quality microscopes, which makes the condenser to be movable and allows very high magnification of above 400X.

16
New cards

rack stop

controls how far the stages should go preventing the objective lens from getting too close to the specimen slide which may damage the specimen

17
New cards

compound microscope

provides a two-dimensional image microscope provides a three-dimensional image.

18
New cards

Scanning Objective Lens (4x)

Lowest magnification (scanner)

19
New cards

Low power objective (10x)

One of the most helpful lenses when it comes to observing and analyzing glass samples

20
New cards

High power objective (40x)

Also called as “high dry” and is ideal for observing fine details in a slide sample

21
New cards

Oil Immersion Objective Lens (100x)

provides the most powerful magnification, with a whopping magnification total of 1000x when combined with a 10x eyepiece. But the refractive index of air and your glass slide are slightly different, so a special immersion oil must be used to help bridge the gap. Without adding a drop of immersion oil, the oil immersion objective lens will not function correctly
