Typically, a compound microscope is used for viewing samples at high magnification (40 – 1000x), which is achieved by the combined effect of two sets of lenses:
the ocular lens (in the eyepiece) and the objective lenses (close to the sample)
.
What is the magnification of a compound light microscope?
Such microscopes are known as compound light microscopes. The objective lenses on a compound light microscope doess have powers that start of as 4x on the smallest power, 10x on the middle power setting and 40x on the maximum power setting. This means that the object can be magnified either,
40x, 100x or 400x
.
What are the 2 lenses in the light microscope that accounts for magnification?
The
objective and ocular lenses
are responsible for magnifying the image of the specimen being viewed. So for 10X objective and 10X ocular, Total magnification = 10 X 10 = 100X (this means that the image being viewed will appear to be 100 times its actual size).
What magnification objective lenses are used in compound microscope?
A compound microscope has multiple lenses: the objective lens (
typically 4x, 10x, 40x or 100x
) is compounded (multiplied) by the eyepiece lens (typically 10x) to obtain a high magnification of 40x, 100x, 400x and 1000x. Higher magnification is achieved by using two lenses rather than just a single magnifying lens.
Which two types of lenses are used in light microscopes?
The light microscope is an instrument for visualizing fine detail of an object. It does this by creating a magnified image through the use of a series of glass lenses, which first focus a beam of light onto or through an object, and
convex objective lenses
to enlarge the image formed.
What Cannot be seen with a light microscope?
With light microscopy, one cannot visualize directly structures such as cell membranes,
ribosomes, filaments
, and small granules and vesicles.
What can you see with a compound light microscope?
- pond water.
- living protists or metazoans, and.
- plant cells such as algae.
What are 2 advantages of using a compound light microscope?
The advantages of using compound microscope over a simple microscope are: (i) High magnification is achieved, since it uses two lenses instead of one. (ii)
It comes with its own light source
. (iii) It is relatively small in size; easy to use and simple to handle.

What does magnification mean in microscopy?
Magnification is
the ability of a microscope to produce an image of an object at a scale larger (or even smaller) than its actual size
.
What kind of lenses are used in compound microscope?
A compound microscope is made of
two convex lenses
; the first, the ocular lens, is close to the eye, and the second is the objective lens.
What is the highest magnification a compound microscope can produce?
The actual power or magnification of a compound optical microscope is the product of the powers of the ocular (eyepiece) and the objective lens. The maximum normal magnifications of the ocular and objective are 10× and 100× respectively, giving a final magnification of
1,000×
.
What is the formula of magnifying power of compound microscope?
For a compound microscope, its magnifying power is given as
m=v0−f0f0(1+Dfe)…
.. (i). Here, v0 is the distance of the object from the objective lens, f0 and fe are the focal lengths of the objective lens and the eye lens respectively and D is the least distance of distinct vision.
What are the 2 main types of microscopes?
