What are the parts of optical microscope?

Components

• Eyepiece (ocular lens) (1)
• Objective turret, revolver, or revolving nose piece (to hold multiple objective lenses) (2)
• Objective lenses (3)
• Focus knobs (to move the stage)
• Stage (to hold the specimen) (6)
• Light source (a light or a mirror) (7)
• Diaphragm and condenser (8)
• Mechanical stage (9)

What are optical parts?

Optical components fall into two basic groups: transmissives and reflectives. Transmissives include lenses, filters, windows, optical flats, prisms, polarizers, beamsplitters, wave plates, and fiber optics; reflectives include mirrors and retroreflectors.

What is the function of the ocular lens on 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.

How microscope works by describing the functions of its optical and mechanical parts?

The optical or light microscope uses visible light transmitted through, refracted around, or reflected from a specimen. Some of the lenses in a microscope bend these light waves into parallel paths, magnify and focus the light at the ocular.

What is the function of optical tube?

The objective of an optic tube is a collecting system (usually consisting of two cemented lenses, less frequently a multilens or catadioptric system). It gives a real reduced and inverted image of a distant object near its own focal plane.

What is the function of ocular lens in a compound light microscope?

There are two optical systems in a compound microscope: Eyepiece Lenses and Objective Lenses: Eyepiece or Ocular is what you look through at the top of the microscope. Typically, standard eyepieces have a magnifying power of 10x. Optional eyepieces of varying powers are available, typically from 5x-30x.

What are the functions of the ocular?

Ocular Lens – The ocular lens, or eyepiece, magnifies the image. It contains a measuring scale called and ocular micrometer.

How does the optical parts of microscope achieve magnification?

In simple magnification, light from an object passes through a biconvex lens and is bent (refracted) towards your eye. Both of these contribute to the magnification of the object. The eyepiece lens usually magnifies 10x, and a typical objective lens magnifies 40x.

What are the parts of compound microscope and their functions?

Compound Microscope Parts

• STRUCTURAL COMPONENTS.
• OPTICAL COMPONENTS.
• Eyepiece or Ocular is what you look through at the top of the microscope.
• Eyepiece Tube holds the eyepieces in place above the objective lens.
• Objective Lenses are the primary optical lenses on a microscope.
• Nosepiece houses the objectives.

What is the function of rotating head in microscope?

Revolving Nosepiece or Turret: This is the part of the microscope that holds two or more objective lenses and can be rotated to easily change power. Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope.

Where is ocular lens on a microscope?

Eyepiece or Ocular is what you look through at the top of the microscope. Typically, standard eyepieces have a magnifying power of 10x. Optional eyepieces of varying powers are available, typically from 5x-30x. Eyepiece Tube holds the eyepieces in place above the objective lens.
