What types of microscope are used in a laboratory?
compound and electron microscopes
What are the different types of microscopes and their purposes?
There are reflective microscopes (similar in design to a telescope), and transmission microscopes where the objective is on the other sample and used for looking at slides. There are phase-contrast microscope, electron microscopes and scanning tunneling microscope.
What are a few facts about the microscope?
Microscopes are used to see objects too small for the human eye. One of the first microscopes was made in 1590 by Zaccharias and Hans Janssen. Galileo later improved their invention in 1609. Three types of microscope: -Optical (uses visible light wavelengths) -Electron (uses electrons to magnify the object) -Scanning probe (uses a physical probe)
How are microscopes used today?
microscopes are used in labs, medical field, surgeries, astronomy and crime investigation field
Is Bright-field microscopes are used for most microscopic work?
Bright field microscopes are most used for microscopic work.
What types of microscopes could be used to study viruses?
Electron Microscopes are used to study viruses.

What types of objects can be studied with a light microscopes. what types can be studied with an electron microscopes?
Light microscopes are used to study living organism and to watch and analyze their structures. Electron microscopes use a dead specimen and are able to observe structures in great detail and with much much higher magnification. +++The electron microscope has a far higher definition and magnification than an optical microscope could achieve, but as you say you could not use it to study a living organism.
When are electron microscopes used?
looking at atoms
Types of microscope and their uses?
Compound microscopes can be found in most biology and science classrooms. They are electrically operated and use light to enhance the image of a cell. They will have multiple lenses for viewing.Dissecting microscopes are also known as stereo microscopes. They have low magnification and are also light powered. These microscopes can view objects larger than what a compound microscope is able to handle, in three dimensions.Scanning Electron Microscopes use electrons instead of light to create an image. These microscopes produce three-dimensional images with high resolution and magnification. They also have a larger depth of focus.Transmission Electron Microscopes use electrons instead of light to create an image. The material prepared must be very thin. The beams of electrons that pass through it give the viewer high magnification and resolution. These give two-dimensional images.Electron microscopes are one of the most advanced microscopes used today. This microscope is powered by a beam of electrons with very short wavelengths. These electrons strike objects that come in its path and helps increase the resolution of the microscope. The electron microscope is one of the types of microscopes used to study cells like tiny viral cells as well as larger molecules.
What are two main types of electron microscopes?
there are several kind of different , we can separate : 1- Methods of analysis 2- properties of Methods of analysis 3-properties of their structure 4-resolution and resoiving power of their (by : S.M Zendehbad)
What two microscope are used to view very small organisms?
Optical Microscopes. Electron Microscopes.
What do electrons microscopes use to focus and magnify an image?
Electromagnets focus the electron beam on the specimen. This is a good advantage of electron microscopes over traditional light microscopes where lenses have to be used. Electromagnets can be used as electrons are charged particles and are deflected by magnetic fields.
Why can't you view living cells through electron microscope?
"In electron microscope the object is viewed in highly vaccum conditions. Living cells would disentegrate in such a condition." This answer is not mine it comes from the "why can't electron microscopes be used to view cell structures" question
How do scientists see the mitochondria and nucleus?
The Nucleus is seen through the use of an Optical Microscope and The Mitochondria is seen through an Electron Microscope.
What is resolution of microscopes?
There is no one resolution for microscopes. The most commonly used resolution is 0.2 micrometers.
