How does a microscope work and what are the parts?
These usually consist of a set of two convex lenses.
The first is facing the object and has a short focal length and aperture.
This is called the objective lens.
The other lens is closer to the viewer’s eye and has a longer focal length and is called the eyepiece.
Both these lenses are mounted coaxially at the two ends of a tube, with the eyepiece closer to the viewer’s eyes.
There are also other types of stereo microscopes and electron microscopes.
The item to be magnified is placed between the focus and the centre of curvature of the objective lens.
It forms a real, inverted magnified image on the opposite of on the objective lens.
This is used as the object by the eyepiece lens, which gives a final even further magnified, virtual and erect image.
This being the fundamental principle, here are the parts of a microscope – you may come across some of these terms:
Eyepiece tube – which holds the eyepiece lens
Nose-piece – which houses the objective lens, which may be a combination of many lenses.
Focus knobs – used to focus the camera objective
Stage – where the specimen is placed
Illuminator – is the light source for the device, usually at the bottom of it – usually a low voltage halogen bulb.
Condensor – used to collect the light from the illuminator and focus it on the specimen
Condensor focus knob– used to adjust the condenser position ( up or down) about the lighting concentrate on the sample.
Iris diaphragm – used to control the amount of light reaching the specimen. It is located above the condenser and below the stage.
Aperture– the hole in the stage through which the base light reaches the stage.
Microscope Camera – these digital cameras are good definition USB imaging systems that can connect to your computer and transmit live images and video to it. Accompanying software is also included.
We have selected five brands in no particular order and picked out the right ones with reviews for your reference.
These tools are designed for low magnification purposes and use two objective lenses and two eyepieces to provide slightly different viewing angles to each of the viewer’s eyes, thereby producing a three-dimensional effect.
Some features like adjustable interpupillary distance, dioptric adjustment, coaxial coarse and fine focusing, NA1.25 Abbe condenser and iris diaphragm are common to all except the last.
