TYPES OF MICROSCOPES
JANSEN MICROSCOPE (1950)

first microscope was
known as the Jansen
microscope. It had three
draw tubes with lenses
placed at the ends of
the tubes.
COMPOUND MICROSCOPE

1.
2.
A compound microscope is illuminated with the
use of light. The light source can be sunlight or
an electric bulb.
TWO TYPES OF COMPOUND MICROSCOPE
LIGHT COMPOUND MICROSCOPE
ELECTRIC COMPOUND MICROSCOPE
A light compound
microscope uses mirrors
to collect sunlight that
illuminates the image.
LIGHT COMPOUND MICROSCOPE
electric compound
microscope uses electric
bulb as light source. It can
create two dimensional
images of the sample
being examined.
ELECTRIC COMPOUND MICROSCOPE
Dissection Microscope
It is used for dissection to
obtain a better view of the
specimen by creating
three-dimensional
images. The magnification
capacity of dissection
microscope is usually
limited until 4 times its
original size (4x) making it
only applicable in
observing large samples.
DISSECTION MICROSCOPE
phase-contrast
microscope is highly
similar to the usual
electric compound
microscope in terms of
appearance except for its
capability to change the
position of light as it
passes through a
transparent sample. The
changes brought by phase
shift in light causes
changes in the brightness
of formed image.
PHASE- CONTRAST MICROSCOPE
fluorescence microscope
is an optical microscope
that requires the use of
fluorescence dye to create
magnified images. This is
usually used to study
reflection and absorption
properties of organic or
inorganic substances
within a minute organism
or cells.
FLUORESCENCE MICROSCOPE
confocal microscope uses a laser light instead of normal light. Laser at
specific wavelength allows more details in the images created by a confocal
microscope. A confocal microscope is used in the field of material science
to study structure and properties of materials to be used for various
purposes.
CONFOCAL MICROSCOPE
ELECTRON MICROSCOPE

An electron microscope is a type of microscope
that uses beam of electrons for to illuminate
images. High magnification and resolution of
specimens being examined is possible because
the wavelength of electron beams is shorter
than visible light.
An electron microscope can provide up to
1000x magnification. It can reveal detailed
structure of smaller objects.
scanning electron
microscope (SEM) is
a type of electron
microscope that can
produce images by
scanning the surface
of the sample using
electron beams. A
SEM is usually used
to determine surface
structure of cells or
small compound
particles.
SCANNING ELECTRON MICROSCOPE (SEM)

transmission electron
microscopy (TEM) is
another type of
electron microscope
that transmits beam of
electrons through the
sample to form an
image. It is used in
examining very thin
section of samples. It
is being used to
examine inner
structure of the cells
and other thin
materials.
