The coarsest classification has the ocular or eyepieceand the objective.
There are many designs for both these components of microscopes.
The objective lens of a microscope is the one at the bottom near the sample. At its simplest it is a very high-powered magnifying glass, with very short focal length. This is brought very close to the specimen being examined so that the light from the specimen comes to a focus inside the microscope tube. The objective itself is usually a cylinder containing one or more lenses that are typically made of glass; its function is to collect light from the sample.
An eyepiece consists of several "lens elements" in a housing, with a "barrel" on one end. The barrel is shaped to fit in a special opening of the instrument to which it is attached. The image can be focused by moving the eyepiece nearer and further from the objective. Most instruments have a focusing mechanism to allow movement of the shaft in which the eyepiece is mounted, without needing to manipulate the eyepiece directly.

What feature is common in all microscopes and how is this feature related in the word microscope?
All microscopes have lenses. Some types of lenses are eyepiece lenses, objective lenses, and condenser lenses.
What are the two different types of microscopes?
Light microscope Electron microscope
Name the two types of microscopes?
There are a variety of microscope types, but two large and different types are electron microscopes and optical microscopes. Optical microscopes are cheaper, and are commercially available for even you to buy. They work with lenses, and in many cases, oil emulsions. Electron microscopes work by bombarding specimens with electron beams. They are significantly more expensive than optical microscopes, but give a better quality image and come with vastly superior magnification levels, due to the fact that electrons have wavelengths circa 100,000 shorter than photons, or light. This enables you to see things in much greater detail.
How many types of microscope are there?
There are many. Simple microscope, compound microscope, light microscope, scanning electron microscope, Transmission Electron Microscope, Dissection microscope, etc,but all together there are about 20 different types of microscopes.

Description of the microscope invented by zaccharias jansson?
Zacharias Janssen invented a compound 9x magnification optical microscope and a single lens optical microscope. It was made up of there draw types with lenses that were inserted within the flanking tubes' end.
Are optical and light microscopes the same?
Yes. The optical microscope is the original light microscope.
What are lens you look through on a microscope?
Microscopes typically have different types of lenses, including objective lenses and eyepiece lenses. Objective lenses are located near the specimen and magnify the image, while the eyepiece (or ocular) lens is located at the top of the microscope and further magnifies the image for viewing.
What are examples of types of lenses?
there are two types of optical fiber,the first type is single mode fibers.the second type is multimode fibers.
What feature is common in all microscopes and how is this feature related in the word microscope?
All microscopes have lenses. Some types of lenses are eyepiece lenses, objective lenses, and condenser lenses.
What is the objective lens on a microscope?
An optical microscope used in a laboratory would have 3 different types of lenses.They are :-(1) Condenser lens- directs light to the specimen if there is no in built light source.(2) Eye piece - lens close to the eye of the observer which magnifies the image created by the objective lens.(3) Objective - These are the lenses which are positioned closest to the specimen mounted on the stage of the microscope which magnifies the specimen. There could be several objective lenses in an optical microscope, generally three. The low power objective (usually magnifies 4 times), mid power objective (usually magnifies 10 times) and the high power objective (usually magnifies 40 times).
What is a compound light?
'Compound light' means a certain type of microscope, separating it from other types like digital microscope or electron scanning microscopes. Compound light microscope is the very traditional type used in laboratories. It has usually a set of lenses for different magnification levels (eg. 150x, 300x, 600x, 900x, 1200x) The object of study under the microscope can be illuminated in different ways to enable one to inspect certain characteristics better.
Which two types of microscopes view the surface of an object?
An optical, and an electron microscope.
How are concave convex and biofocle lenses alike?
Concave, convex, and bifocal lenses are all types of optical lenses that are used to correct vision problems. Concave lenses are thinner in the center and thicker at the edges, diverging light rays. Convex lenses are thicker in the center and thinner at the edges, converging light rays. Bifocal lenses have two different optical powers, typically one for distance vision and one for near vision, allowing individuals with presbyopia to see clearly at different distances.
What is optical instrumentation?
Optical instrumentation is the science of developing, manufacturing, and utilizing tools for optical purposes. This may include developing new types of optical surgeries or manufacturing glasses lenses.
What is an Optical Associate?
An optical associate is a person that assists customers with selecting frames and lenses for customers needing glasses. Optical associates also educate customers on various types of lenses, interpret prescriptions for eyewear and general retail sales.
How many microscope are there?
There are six different types of microscopes used in the life science. There is the light microscope, phase contrast microscope, fluorescent microscope, electron microscope, atomic force microscope, and scanning tunnelling microscope.
