2012 COMPOUND MICROSCOPE A compound microscope is an optical instrument used to see objects that are too 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

Compound Light Microscope The familiar compound light microscope is a series of lenses (hence "compound") that focus visible light in such a way as to produce a magnified image. A single lens‚ often called a magnifying glass‚ cannot generally magnify images as much as a series of lenses although Antony van Leeuwenhoek‚ the first microbiologist‚ used a simple‚ albeit exquisitely crafted‚ lens to discover single-celled "animalcules‚" as he called them. Advantages: Basic compound light microscopes

The Compound Light Microscope Commonly binocular (two eyepieces)‚ the compound light microscope‚ combines the power of lenses and light to enlarge the subject being viewed. Typically‚ the eyepiece itself allows for 10X or 15X magnification and when combined with the three or four objective lenses‚ which can be rotated into the field of view‚ produce higher magnification to a maximum of around 1000X generally. The compound light microscope is popular among botanists for studying plant cells‚ in

for final‚ sharp focusing Coarse adjustment: is used initially for rough focusing Parfocal: as you cane from one objective to another you will find that your microscope is very close to a final focus Sub stage condenser: light focusing lens Iris diaphragm: used to regulate the intensity of light entering the lens system of the microscope Mechanical stage: allows total movement of the slide by turning bot knobs beneath the left side of the stage‚ one for to-and-fro‚ one for the left and right positioning

of the parts of the microscope 1. Stage The horizontal surface upon which the slide is placed is called the stage. The slide is held in place by spring loaded clips and moved around the stage by turning the geared knobs on the stage. Th stage has two perpendicular scales that can be used to record the position of an object on a slide. This is useful if you want to quickly relocate an object. 2. Coarse adjustment The coarse adjustment knob located on the arm of the microscope moves

Snaps will be submitted separately. 2. Describe the relationship between what you see through the eyepiece and what you see on the stage. On the stage it was not visible enough rather it looks too small‚ while in microscope it appears black and grainy. 3. Draw the image you see of the ‘e’ slide at 200x. Snaps
