What is a compound light microscope?

A compound light microscope is an optical instrument that uses lenses and light to magnify small objects.

What is the typical magnification range of a compound light microscope?

The magnification range is usually from 40x to 1000x.

What types of specimens can be viewed with a compound light microscope?

Cells, tissues, microorganisms, and larger cellular organelles can be observed.

What is a stereo microscope?

A stereo microscope, also known as a dissecting microscope, is designed for viewing larger specimens in 3D. It uses two optical paths to create a three-dimensional image

What is the typical magnification range of a stereo microscope?

The typical magnification range is from 10x to 50x

What are the applications for a stereo microscope?

To examine larger specimens such as insects, plants. Often used in dissections

Transmission electron microscope (TEM)

Passes electrons through thinly sliced specimens which provides high resolution images of internal structures.

What is the applications for a Transmission electron microscope?

To observe ultra structures

What is the magnification range of a transmission electron microscope?

50 000x tp 1000000

What is a Phase-Contrast Microscope

It enhances contradt in transparenct or unstained specimens by using differences in light refraction.

What is the magnification of a Phase-Contrast Microscope

40x-1000x

What is the application of a Phase-Contrast Microscope?

To study crystalline structures, fibres and minerals

What is the definition of a Darkfield microscope?

It illuminates specimens with oblique light to enhance contrast in unstained samples.

What is the magnification range of a Darkfield Microscope?

40x-1000x

What is the application of a Darkfield microscope ?

To observe living microorganisms and transparent cells.

Toxic symbol

Indicates that substances that are held in the lab are poisonous.

Glassware

Indicates that the tool is made up of glass which can be fragile.

Hot surface

Indicates that there is a hot surface to warn the possibilities of burn hazards.

Corrosive

Indicates that there is corrosive materials present in the lab which could burn skin or eat away at materials

General warning

This indicates a broad reminder that the lab is likely to have hazards and risks.

Biohazard

This indicates that the lab contains bio hazardous materials

Explosive materials

Indicates that there are chemicals with explosive properties in the area.

Flammable

Indicates that flammable materials are likely to be present in the lab

What is the function of a Ocular (eyepiece)

Its the lens closest to the eye. Its used to magnify the object.

What is the function of a tube?

It holds the eyepiece and connects it to the rest of the microscope.

What is the function of a nosepiece.

It holds the objectives and can be rotated to select the appropriate objectives.

What is the function of a objective?

What is the function of a clamp?

It holds the slide in place while the object mounted on the slide is being studied.

What is the function of a platform/stage?

Its a flat horizontal surface located just below the objectives. It has a hole so that light can shine through it.

What is the function of a condenser?

The

What is the function of a diaphragm?

What is the function of a mirror?

The mirror reflects sunlight upwards onto/through the object.

What is the function of a base?

The microscope rests on the base . The base has pieces of rubber attached on the bottom so the microscope stands firmly.

What is he function of a fine adjustment knob?

Its used to get the image of the object onto focus with small movements.
