Oct 27, 2024 · Optical parts of a microscope and their functions. The optical parts of the microscope are used to view, magnify, and produce an image from a specimen placed on a slide. These parts include: Eyepiece – The eyepiece (ocular Lens) is closest to the viewer’s eye. They are located at the top of the microscope. This part is used to look at the ...
- Head (Body) The head, also referred to as the body of the microscope, is a structural component that contains the optical parts of the microscope. The figure below shows the area of the microscope considered to be the body of the microscope.
- Arm. The arm of the microscope is another structural piece. The arm connects the base of the microscope to the head/body of the microscope. If you watched any lab safety videos, you’ll probably see the arm referenced as one of the pieces you should hold on to when carrying microscope.
- Base. The base is the last structural piece of the microscope. The base is at the bottom of the microscope and is used to support the microscope. A heavier based tends to be a more desirable feature because it reduces the chance of slight movements throwing off the focus and view of the microscope.
- Eyepiece. The eyepiece, also known as the “Ocular”, is the first magnification lens you will look through in a compound microscope. Put simply, this is where you put your eye to see the image.
In addition to catoptric objectives, mirrors play an important role in fluorescence microscopy, where they act as dichromatic beamsplitters to direct excitation wavelengths toward the specimen, and then block the same light after it has been reflected back through the objective. Other parts of the microscope also incorporate mirrors.
- Eyepiece – The eyepiece contains the ocular lens. It’s found at the top of the microscope. Its standard magnification is 10X with an optional eyepiece having magnifications from 5X – 30X.
- Eyepiece tube – This is the eyepiece holder. It carries the eyepiece just above the objective lens. In some microscopes such as the binoculars, the eyepiece tube is flexible and can be rotated for maximum visualization, for variance in distance.
- Objective lenses – There are generally 3 or 4 objective lenses in a microscope. They almost always consist of 4x, 10x, 40x and 100x powers. The objective lens gathers light from the specimen, magnifies the image of the specimen, and projects the magnified image into the body tube.
- Revolving Nose piece – also known as the revolving turret. Several objective lenses of varying magnification and numerical aperture are mounted on the revolving nosepiece.
May 10, 2022 · Parts of a microscope. A compound microscope uses two or more lenses to produce a magnified image of an object, known as a specimen, placed on a slide (a piece of glass) at the base. The microscope rests securely on a stand on a table. Daylight from the room (or from a bright lamp) shines in at the bottom.
Nov 18, 2020 · Common compound microscope parts include: Compound Microscope Definitions for Labels. Eyepiece (ocular lens) with or without Pointer: The part that is looked through at the top of the compound microscope. Eyepieces typically have a magnification between 5x & 30x. Monocular or Binocular Head: Structural support that holds & connects the ...
