A magnifying lens is an optical
instrument that permits you to see objects amplified. A few magnifying
instruments are strong to the point that you can see things that the human eye
can't see alone like cells, fiery debris, and snowflakes. A straightforward
magnifying lens is one that uses stand out lens to amplify, for example, an
amplifying glass. A compound magnifying lens utilizes two or more lenses to
amplify the example. The magnifying instrument you have at school likely uses a
blend of lenses to amplify, yet for their exploration a few researchers have
magnifying lens that utilization gadgets to amplify. They are called electron
magnifying lens. There are numerous different sorts of magnifying instruments
including ones that utilization x-beams, gasses, and lasers. Magnifying lens
permit us to see what makes individuals wiped out and how life forms work. We
can concentrate eager for advancement up of rocks, and even liquids. For
instance, we can see precisely what is in a glass of drinking water.
Parts of a microscope:
The Eyepiece is the top part. it is
the lens to look through to see specimen.
It’s the large metal band attaching
the base to the lens and eyepiece. When carrying a microscope, use one
hand to hold the Arm and the place the other under the base
The Fine Adjustment Knob is the
smaller round knob on the side of the microscope used to fine-tune the focus of
your specimen after using the coarse adjustment knob.
d) Coarse: Adjustment Knob:
Of the two knobs on the side of a
microscope, it is the largest. It is used to focus on the specimen;
it may move either the stage or the upper part of the microscope. Always
focus with the coarse knob first.
Most microscopes have 2, 3, or more
lenses that magnify at different powers. Always start with the
lowest power and work your way up to the strongest when examining a specimen. The
shortest lens is usually the lowest power.
Where the sample or specimen is
placed for examination is called stage.
It’s what allows you to control the
amount of light on the specimen that comes through the stage.
It can be a bulb or a mirror, and is
usually found near the base of the microscope shining up through the stage.
It’s the hole in the stage that
allows light through for better viewing of the specimen.
