Why may it be necessary to continually focus a microscope?

It may be necessary to continually focus a microscope so as to get accurate results about a specimen. This will give you enough time to study any specimen.


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 Microscope that gives 3-D image?

There are at least two types of microscope that can give 3D images. Confocal microscopes that use lasers to illuminate the object and scanning electron microcopes (SEM) that use an electron beam. A SEM can give better magnification than confocal but confocal can image live moving subjects. In SEM the object of intrest must be coated with gold so only dead things can be imaged.
