1) The Light Microscope was made in 1595, when Zacharias Jansen of Holland invented a compound light microscoope, one that used two lenses, with the second lens further magnifying the image produced by the first.

1) Light microscopes date at least to 1595
2) Creates a magnified image through a series of glass lenses.
3) You can see bacteria and some organelles like mitochondria POWER HOUSE OF THE CELL
4) They were used to study living things and their cells further our knowledge in biology.

2) fires a beam of electrons through a specimen to produce a magnified image of an object. it uses a high voltage electron beam in order to create an image.
3) thin specimens that electrons can pass through generating a projection image
4) it magnifies specimens to a much higher degree than an optical microscope. It can magnify 10,000 times and more, which allows scientists to see extremely small structures.

Answer to 3: the light microscope can see most bacteria, plant and animal cells, and ant eggs (although you can see ant eggs with the naked eye too)

1) 1950s
2) Works by passing a laser beam through a light source aperture which is then focused by an objective lens into a small area on the surface of your sample and an image is built up pixel-by-pixel by collecting the emitted photons from the fluorophores in the sample.
3) Obtains high res images of small sections of a specimen.
4) It has allowed scientists to make detailed photos of sections of a specimen.

An X-ray microscope uses electromagnetic radiation in the soft X-ray band to produce magnified images of objects. Therefore, an X-ray microscope exposes film or uses a charge-coupled device (CCD) detector to detect X-rays that pass through the specimen.

Electron microscopes work differently to normal microscopes as they replace the source of light that shone up towards the specimen and lens by an beam of very fast moving electrons. The specimen on the stage is prepared by creating a vacuum chamber so that the electrons cannot travel far. The lense is a series of coil shaped electromagnets that the electron beam travels through. The coils bend the electron beams the same way. The image is formed as a photograph, or electron micrograph, that is seen as an image or TV screen.

Helped us see cells for the first time. Can help us see living and dead microorganisms

Charged Coupled Device detector is used to see the insides of a solid opaque object

You don't have to prepare the specimen to look at it

The SEM is used to examine the surface composition of cells and other products.

1) 1845
2) The basic task of the fluorescence microscope is to let excitation light radiate the specimen and then sort out the much weaker emitted light from the image. The radiation collides with the atoms in your specimen and electrons are excited to a higher energy level. When they relax to a lower level, they emit light.
3) Living cells and tissues
4) Furthered our knowledge about cells.

It is still in it's early stages, but it provides good magnification and depth of field without damaging the specimen

The SEM microscope allowed for the images to be seen in 3D instead of 2D. This benefits further research into cells and their development.

the helium ion microscope works similarly to an electron microscope. it fires charged helium ions out through the lens and onto the object being viewed. the ions will then bounce off of the object and into a range of processors situated around the object. the processor then detect aspects such as angle t which the helium ions hit the processors and time taken to display an image of the object on a screen.
