Types of Microscopes

Front

What is a Scanning Electron Microscope (SEM)?

Back

A type of electron microscope that provides detailed 3D images of the surface of a specimen.

Front

What is a Transmission Electron Microscope (TEM)?

Back

An electron microscope that transmits electrons through a specimen to provide detailed images of internal structures.

Front

What is a Compound Light Microscope?

Back

A microscope that uses visible light and a system of lenses to magnify small objects, typically up to 1000X.

Front

What is a Dissecting Microscope?

Back

A low-power microscope used to view larger, three-dimensional specimens, typically with magnification under 100X.

Front

What is the principle behind electron microscopy?

Back

Electron microscopy uses beams of electrons instead of light to create images, allowing for much higher resolution.

Front

How do you calculate total magnification in a light microscope?

Back

Total magnification = eyepiece magnification x objective lens magnification.

Front

What is the main difference between SEM and TEM?

Back

SEM provides 3D images of surfaces, while TEM provides 2D images of internal structures.

Front

What type of specimen can be viewed with a Dissecting Microscope?

Back

Larger specimens such as insects, plants, and small animals.

Front

What is the role of the objective lens in a microscope?

Back

The objective lens gathers light from the specimen and magnifies the image.

Front

What is the role of the eyepiece in a microscope?

Back

The eyepiece further magnifies the image produced by the objective lens.
