What are the 3 illuminating parts of microscope?

It consists of mainly three parts: Mechanical part – base, c-shaped arm and stage. Magnifying part – objective lens and ocular lens.

What are the 4 magnifications on a microscope?

Magnification: Your microscope has 4 objective lenses: Scanning (4x), Low (10x), High (40x), and Oil Immersion (100x).

Where is the lamp on a microscope?

The most common source for today’s microscopes is an incandescent tungsten-halogen bulb positioned in a reflective housing that projects light through the collector lens and into the substage condenser. Lamp voltage is controlled through a variable rheostat that is commonly integrated into the microscope stand.

What are the parts of a microscope?


  • 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.
  • Coarse and Fine Focus knobs.
  • Stage.
  • Stage Clips.
  • Aperture.

What are the magnifications on a microscope?

The most common objective lens magnifications for typical laboratory microscopes are 4x, 10x and 40x, although alternatives of weaker and stronger magnification exist.

What are the different magnifications on a microscope?

The compound microscope typically has three or four magnifications – 40x, 100x, 400x, and sometimes 1000x.

  • At 40x magnification you will be able to see 5mm.
  • At 100x magnification you will be able to see 2mm.
  • At 400x magnification you will be able to see 0.45mm, or 450 microns.

What does a diaphragm do on a microscope?

Opening and closing of the condenser aperture diaphragm controls the angle of the light cone reaching the specimen. The setting of the condenser’s aperture diaphragm, along with the aperture of the objective, determines the realized numerical aperture of the microscope system.

What are parts of a microscope?

The Different Parts Of A Microscope

  • The compound microscope was originally invented in 1590 by Zacharias Janssen, a Dutch optician.
  • Eyepiece.
  • Eyepiece Tube.
  • Objective Lenses.
  • Stage.
  • Illuminator.
  • Diaphragm or Iris.
  • Coarse Adjustment Knob.

Where is the eyepiece on a microbus microscope?

Eyepiece Lens: the lens at the top of the microscope that you look through. They eyepiece is usually 10x or 15x power. Tube: Connects the eyepiece to the objective lenses.

How are specimens mounted in a compound microscope?

Specimen or slide: The specimen is the object being examined. Most specimens are mounted on slides, flat rectangles of thin glass. The specimen is placed on the glass and a cover slip is placed over the specimen. This allows the slide to be easily inserted or removed from the microscope.

What do the adjustment knobs on a microscope do?

The Adjustment knobs – These are knobs that are used to focus the microscope. There are two types of adjustment knobs i.e fine adjustment knobs and the coarse adjustment knobs. Stage – This is the section on which the specimen is placed for viewing.

Where are the condensers located in a microscope?

Condenser – These are lenses that are used to collect and focus light from the illuminator into the specimen. They are found under the stage next to the diaphragm of the microscope. They play a major role in ensuring clear sharp images are produced with a high magnification of 400X and above.
