Bright field microscope : used by Biology students
Dark field microscope : Improves apparent resolution to see smaller structures in cells. Used to view unstained specimens.
Phase contrast microscope : Makes many structures within a living cell highky visible without staining or altering the cell.

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 is the function of an objective lens on a microscope?
Objective lens on a microscope collects the light emerging from the sample and focuses it into the objective turret. Its primary role is to increase the magnification used for viewing.usually, there are three or four objective lenses on a microscope,
How is a stereo microscope different from a compound microscope?
Compound microscope - a microscope which uses multiple lenses to collect light from the sample, and then a separate set of lenses to focus the light into the eye or camera. It shines a light from beneath the stage, going up through the object being examined.Stereo microscope - a microscope designed for low magnification observation of an opaque object. It shines a light onto the object, rather than shining it up through the object. It uses two separate optical paths with two objectives and two eyepieces to provide slightly different viewing angles to the left and right eyes. This produces a three-dimensional visualization of the object.
What are the three things you shouldn't do when using the microscope to view your own cells?
You should never use direct sunlight as a light source, never hold with one hand, and do not drop it.
What type of microscope is best for studying DNA?
electron microscopes...According to my course in OK Virtual Highschool.."Hi-tech electron microscopes are used to study very small objects such as viruses. They can also be used to view the smallest of molecules that make up cells such as DNA in the nucleus. Unlike a compound microscope, an electron microscope can produce a three-dimensional image"
Which microscope would you use if the object is to thick to let light through?
A Light stereoscope microscope; this type of microscope is used to see three dimensional views of objects too thick to let light pass through.
What are three things that have been used in a microscope?
Lens, light, mirror
What is the source of radiation of a dissecting microscope?
The source of radiation of a dissecting microscope is light. The illuminated light is what will cause the image to appear in three-dimensional format.?æ

What makes a microscope work?
There are three types of basic microscopes: Electron Microscopes, Simple Light Microscopes, and Compound Light Microscopes. Simple [light] Microscopes work by focusing light through one lens. The most common lens, the Convex Lens, works by being thicker in the center than the edge. This bends the light, altering the image as it hits the second lens, your retina. A Compound [light] Microscope works differently. It is the most common microscope for everyday use, using a mirror to shine light up through a slide containing a specimin. Next, the ray of light shines up through a series of lenses, bending the light and multiplying the magnification and resolution levels of the image, until it hits your retina. Robert Hooke used a very complex compound microscope to observe cells through a thin slice of cork wood. The Electron Microscope is the most technologically advanced and, in my opinion, the coolest type yet. In fact, the electron microscope was so complex that it was not discovered until the late 1930's. It uses a beam of electrons instead of light to magnify an image. This allows you to get a much closer image with much higher resolution than with a regular light microscope. The most complex light microscope can only magnify an image up to 5000 times. An electron microscope can easily double that, a recently founded electron microscope can magnify an image up to 150,000 times. To work, this microscope actually borrows electrons from atoms, and as long as they return the electrons to the atoms, there is still perfect balance.

Does a compound microscope have one lens?
Most microscopes have 4 to 5 lenses. The lenses are:The three Objects (which are the three things that you use to microscope)The lens that you you put your on.And the mirror lens.
What are the three main parts of a compound microscope?
The compound microscope has three main parts, The three main parts of a microscope includes the illuminating parts, the magnifying parts, and the mechanical parts.
