microscope parts and functions

• the objective lenses are located below the stage, they magnify the image produced by the specimen
• the eyepiece is the lens closest to your eye
• the condenser lens focuses light onto the specimen from above
• the ocular lens is also called an eyepiece or eye piece it sits on top of the tube assembly and has a magnification power of about 10x
• a higher magnification means that more detail can be seen but less field of view will be visible at one time
• the total magnification of a compound light microscope is calculated by multiplying the magnifications of both the objective lens and the ocular lens together
• the ocular or eyepiece has a magnification power of about 10x
• total magnification = objective x eyepiece
• the total magnification of an optical microscope is equal to the product of the magnifications of both the objective and the eyepiece
• the illuminator provides light that passes through the specimen
• the total magnification of an optical microscope is equal to the product of the magnifications of both the objective and the eyepiece
• a compound microscope has two or more lenses which can be adjusted independently
• the diaphragm controls how much light enters the microscope
• magnification = total magnification x objective magnification
• the coarse focus knob moves the entire body of the microscope up and down
• magnification = total magnification x objective magnification
• compound microscopes have higher resolution than simple microscopes because they use multiple lenses
• magnification = total magnification x objective magnification
• the stage holds the slide being viewed
• the objective lenses have different powers of magnification, usually ranging from 4x to 100x
• the stage holds the slide being viewed
• light microscopy uses visible wavelengths of light to produce images
• the illuminator provides light to the specimen
• resolution refers to how close two objects must be so that they appear as separate images rather than being fused into one blurry image
• total magnification = objective magnification + ocular magnification
• total magnification = objective x ocular
• the stage clips are used to hold slides firmly in place while viewing them under high magnification
• the stage holds the slide and allows it to move up and down so different areas of the sample can be viewed
• the stage clips are used to hold the slides in place while they are being observed
• the coarse adjustment knob allows the user to move the entire stage up and down
• the condenser focuses the light onto the specimen
• an iris diaphragm controls the amount of light passing into the microscope
