the knob. Because of this‚ the coarse adjustment should only be used with low power (4X and 10X objetives) and never with the high power lenses (40X and 100X). 3. Fine adjustment This knob is inside the coarse adjustment knob and is used to bring the specimen into sharp focus under low power and is used for all focusing when using high power lenses. 4. Ocular lens The ocular lens‚ or eyepiece‚ magnifies the image. It contains a measuring scale called and ocular micrometer. The ocular

viewing very small objects‚ typically magnified several hundred times. It consist of different lenses such as: Scanning = 4X‚ Low power = 10X‚ High power = 40 or 43X‚ Oil Immersion = 100X. A microscope is an instrument to see objects too small for the naked eye. It’s a device used for magnifying small entities which cannot be seen by the eyes without any additional aid‚ it uses combination of magnifying lenses with a rotator that can be used to adjust the item view option. It is made out of glass that

Nosepiece - Holds the different objective lenses; allows the lenses to rotate for viewing. 6. Base - Supports the microscope. One hand is placed under this when carrying the microscope. 7. Eyepiece - Contains a lens that magnifies about 10X. You look through this. 8. Fine Adjustment Knob

To properly clean the microscope you clean it with lens cleaner and lens paper so it does not scratch the lenses. You clean off all lenses including ocular lenses. Be sure not get the oil on the 10x or 40x objective. Lower stage and nose piece and set to 10x objective.

small for the naked eye. A compound microscope is a microscope fitted with two or more convex lenses. The high magnification produced by these lenses together enables a detailed study of micro-organisms‚ cells and tissues. These types of microscopes are therefore widely used in scientific and medical research. The basic design of a compound light microscope consists of convex lenses fitted at either end of a hollow tube. This tube is fitted on an adjustable‚ rotary nosepiece. There

optical microscope widely use in the field of cell biology‚ microbiology‚ biotechnology‚ pharmacology‚ forensic and medical diagnosis especially when dealing with tissue fragments. It is a type of microscope which uses visible light and a system of lenses to magnify images of small samples. In other words‚ Optical microscope is a technical device which is used for visualizing structures that are too small to see with the unaided eye. The LED of microscope features a long service life of 20‚000 hours
