What is objective and eyepiece?
The objective, located closest to the object, relays a real image of the object to the eyepiece. This part of the microscope is needed to produce the base magnification. The eyepiece, located closest to the eye or sensor, projects and magnifies this real image and yields a virtual image of the object.
What do you mean by nose piece and objectives of a 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. They almost always consist of 4x, 10x, 40x and 100x powers.
What is objective piece in microscope?
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.
What is nosepiece microscope?
Medical Definition of nosepiece 1 : the end piece of a microscope body to which an objective is attached and which often consists of a revolving holder for two or more objectives. 2 : the bridge of a pair of eyeglasses.
What is the function of nosepiece in microscope?
Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power.
What is nose piece in microscope?
Is nosepiece a magnifying?
The revolving nosepiece holds multiple lenses, allowing the user to turn it to achieve various levels of magnification. Though the exact level of magnification may vary with different models, most microscopes provide a low power lens with about 5x magnification and a high power lens with about 100x magnification.

Where is the nosepiece on a microscope?
A microscope user will find the revolving nosepiece between the ocular lens (the eyepiece) and the stage (where the microscope holds slides and other objects for viewing). On most models, the revolving nosepiece attaches to the lower portion of the microscope’s arm.
What is the revolving nose piece?
The revolving nosepiece is the inclined, circular metal plate to which the objective lenses, usually four, are attached. The objective lenses usually provide 4x, 10x, 40x and 100x magnification.
What is a nose piece?
Definition of nosepiece 1 : a piece of armor for protecting the nose. 2 : the end piece of a microscope body to which an objective is attached. 3 : the bridge of a pair of eyeglasses.
nose•piece. n. 1. the part of an eyeglass frame that passes over the bridge of the nose. 2. the part of a microscope to which the objectives are attached. 3. a piece of armor serving as protection for the nose.
The nosepiece plays a similar role for the microscope. The microscope nosepiece, also known as the revolving turret, sits below the head of the microscope and locks the objective lens into position over the stage aperture by rotating in either direction.
How does the revolving nosepiece work?
The revolving nosepiece revolves by grasping the objective along the etched grip section of the objective lens and rotating it either clockwise or counterclockwise depending on which objective you are trying to lock into position.
How do you identify a nosepiece on an inverted microscope?
The nosepiece is easily identifiable because it has a distinct disc shape and it will have the objective lenses screwed into it. On an inverted microscope the nosepiece is located underneath the stage with the objectives pointed upward. The nosepiece on an inverted microscope works the same way as a standard microscope.
