The microscope optical train typically consists of an illuminator (including the light source and collector lens), a substage condenser, specimen, objective, eyepiece, and detector, which is either some form of camera or the observer’s eye (Table 1).
What are optical parts?
Optical parts, also known as optical elements. The basic component unit of an optical system. Most optical components play an imaging role, such as lenses, prisms, mirrors, etc.
What are optical parts of a microscope and their functions?
Optical parts of a microscope and their functions
- Eyepiece – also known as the ocular.
- Eyepiece tube – it’s the eyepiece holder.
- Objective lenses – These are the major lenses used for specimen visualization.
- Nose piece – also known as the revolving turret.
What are the three optical parts of compound microscope?
These key microscope parts are illustrated and explained below. The three basic, structural components of a compound microscope are the head, base and arm.
What are two basic optical element of a microscope?
Lens and mirror
The two most common elements for imaging objects are the converging lens and the concave mirror. Lenses are more common in optical microscopes; therefore we will concentrate on lenses in the following exploration of the basic microscope functions.
How does the optical parts of a microscope achieve magnification?
All Rights Reserved. In simple magnification, light from an object passes through a biconvex lens and is bent (refracted) towards your eye. It makes it appear to have come from a much bigger object. In practice, modern microscopes contain a series of lenses rather than just one.
What are the 12 parts of a microscope?
Function of each Microscope Part
- Eyepiece or Ocular Lens. Eyepiece lens magnifies the image of the specimen.
- Eyepiece Tube or Body Tube. The tube hold the eyepiece.
- Nosepiece.
- Objective Lenses.
- Arm.
- Stage.
- Stage Clips.
- Diaphragm (sometimes called the Iris)
Where is the ocular lens on a microscope?
While an objective is on the side of the observed object, the ocular lens (also called ocular or eyepiece, sometimes loupe) is on the side of the observing eye. It may contain a single optical lens or some combination of lenses and is normally placed in a cylindrical housing (barrel).

What is the function of an ocular lens in a microscope?
The eyepiece, or ocular lens, is the part of the microscope that magnifies the image produced by the microscope’s objective so that it can be seen by the human eye.
What are the 11 parts of a compound microscope?
Parts Of Compound Microscope
- Foot or base. It is a U-shaped structure and supports the entire weight of the compound microscope.
- Pillar. It is a vertical projection.
- Arm. The entire microscope is handled by a strong and curved structure known as the arm.
- Stage.
- Inclination joint.
- Clips.
- Diaphragm.
- Nose piece.
What is the main component of an optical microscope that is used to focus an image at a high power of magnification?
Condenser Lens: The purpose of the condenser lens is to focus the light onto the specimen. Condenser lenses are most useful at the highest powers (400x and above). Microscopes with in-stage condenser lenses render a sharper image than those with no lens (at 400x).
What is the magnification of the ocular lens?
10X
Magnification: the process of enlarging the size of an object, as an optical image. Total magnification: In a compound microscope the total magnification is the product of the objective and ocular lenses (see figure below). The magnification of the ocular lenses on your scope is 10X.
What are the parts of the microscope that magnify the image of the specimen?
Answer: Ocular Lens – The ocular lens, or eyepiece, magnifies the image. It contains a measuring scale called and ocular micrometer. The ocular micrometer has no units.
What are the different parts of a compound microscope?
Compound Microscopes
- Ocular (eyepiece) lens.
- Objective turret or Revolver (to hold multiple objective lenses)
- Objective.
- Focus wheel to move the stage.
- Frame.
- Light source, a light or mirror.
- Diaphragm or condenser lens.
- Stage (to hold the sample)
What are the parts of simple microscope?
What Are The Parts Of Simple Microscope?
- Eyepiece: It is the lens that is used to study the samples and is placed at the top.
- Base: This provides support to the microscope.
- Tube: This is used to connect the eyepiece to the objective lenses.
What are the terms of microscope?
Glossary of Terms
- Abbe Condenser. – see condenser.
- Aperture. – numerical, a measure of the resolving power of the power of an objective respectively.
- Abberation. – see chromatic and spherical.
- Achromatic. – term referring to the lens.
- Analyzer. – see polarizer.
- Barrel Focus.

What are the parts of a microscope quizlet?
Terms in this set (29)
- Base. Supports the microscope.
- Arm. Used to carry the microscope.
- Stage. Platform where the slide with the specimen is placed.
- Stage Clips. Holds the slide in place on the stage.
- Eyepiece (containing ocular lens)
- Revolving nosepiece.
- Objective lenses.
- Coarse adjustment knob.
How many ocular lenses does a microscope have?
An ocular lens consists of one to three lenses and is also provided with a mechanism, called a field stop, that removes unnecessary reflected light and aberration. Different types are available according to the magnification they provide, such as 7x and 15x.
What contains the ocular lens?
Eyepiece: contains the ocular lens, which provides a magnification power of 10x to 15x, usually.This is the part that holds two or more objective lenses and can be rotated to easily change power.
Which part of an optical microscope contains the magnifying lens?
The eyepiece has a moderate magnification of 5–10X. The objective lens does too but your eye can’t see through the small lens. The eyepiece is intended to send the image to the eyeball by design. A true magnifying glass is still the best way to look at things because it is so much wider than an eyepiece.
