◄II Two basic types of Microscope II► 1. Simple Microscope → A microscope having one lens or lens system, such as magnifying glass. 2. Compound Microscope → Commonly used by Biologist, Doctors and Researches. ◄II Parts of Compound Microscope II► 1. Body Tube → A simple tube mouthed on a stand which holds the objective at the lower end and the eyepiece at the upper end. It also support the eyepiece. 2. Eyepiece → The lens that located at the upper end of the body tube used to view the object being examined. 3. Objective Lens a. Low Power Objective → Less use to enlarge on object 10x its size. b. High Power Objective → Less use to magnify object more than to times its size. 4. Coarse Adjustment → a knob located at the side of the arm used to used to adjust the object lens in focus the image. 5. Arm → Holds the microscope together, and connect the base and stage with the tube. 6. Stage → The flat form where the slides are place for examination. 7. Stage Clip → The tools used to hold the slide on the stage. A metal clips that hold a slide securely onto the stage. 8. Mirror → The instrument designed to reflect light to the diaphragm for better optical perception of the objective. This direct light upwards onto the slide. 9. Fine Adjustment → a knob that is used to improve the image viewed under the High Power Objective. 10. Draw tube → holds the ocular eyepiece. 11. Dust Shield → prevent dirt and dust to penetrate into the objectives. 12. Revolving Nose piece → holds the objective in places and help in shifting of objective to other. 13. Iris Diaphragm → Regulates the amount of light that enters to the condenser . 14. Condenser → It receive the light reflected by the mirror and absorb by the iris diaphragm. 15. Base → it is the bottom of the microscope and it support the entire microscope. 16. Inclination Joint → used in titling the microscope. It is also an adjustable joint that lets the arm tilt at various angle.
