Lab Reports | Using Microscopy

Microscopes are required in examining cells in every sort of aspect including shape of structure , size and many others. In achieving the exact image of the particular microorganism being obseved , the observer must perform the right technique to obtain any visible image of the microorganism. Oil imersion objective is used to observe the microorganism closely after staining. While the condition of the microorganism can be determine and studied through wet mount methods.

DCMSL considers the light microscope to be one of the most important basic tools in a laboratory. Analytical microscopy draws on techniques used in the fields of geology, chemistry, biology and forensics. Microscopy provides rapid, non-destructive analysis and requires very little material. Optical properties of materials are identified and may be compared to the properties of known standards.

Microorganisms are commonly very small in size. So, when comes to observing them through our naked eyes are absolutely impossible. The solution to overcome this problem is by observing them using microscope. Although microscopes comes with various type of models and applications ( such as electron microscopic and The Scanning Probe Microscope ) , the  most basic microscope with simple way of handling would be the light microscope. Despite their disadvantages comparing to other advance microscope , they are still capable of viewing microorganism. This instrument also the most generally use by beginners such as students.

When the coarse-focus is turned, the stage moves up or down, in order to adjust the focus.  The fine-focus adjustment knobs is used fine to ajust the focus.  The light microscope usually has three or four objective lenses on a microscope.  They consist of 9x, 65x, 95x and 655x magnification powers.  The objective lens focuses the light passing through the specimen to form a magnified primary images.

• Swift point counter. An attachment to the microscope which enables an analyst to count and tally particles and/or fibers by use of an automated stage and microprocessor.

The condenser diaphragm controls the intensity and size of the cone light projected on the specimen.  This will make sure that the correct amount of light enters the objective lens.  The stage is the flat platform that support the slide being observed.  The stage may be moved backwards or forwards and from left to right by using coaxial knobs.
