Field of view - area of the specimen that can be seen through the microscope with a given objective lens Focal length - distance required for a lens to bring the light to a focus (usually measured in microns) Focal point/focus - point at which the light from a lens comes together Magnif...
The image must be reduced in size to fit onto the retina. The scattered light must come together -- that is, it must focus -- at the surface of the retina. The image must be curved to match the curve of the retina. To do all that, the eye has a lens between the retina and the...
It brings the image of the object into focus at a short distance within the microscope's tube. The image is then magnified by a second lens, called an ocular lens or eyepiece, as it is brought to your eye. The other major difference between a telescope and a microscope is that a ...
Some of the lenses in a microscope bend these light waves into parallel paths, magnify and focus the light at the ocular.How Does a Microscope Work? - MagnificationThe power to enlarge the image of the specimen when viewed through a microscope is known as the magnification and is dependent ...
If you cannot focus on your specimen, repeat steps 4 through 7 with the higher power objective lens in place.Do not allow the objective lens to touch the slide! 9. The proper way to use a monocular microscope is to look through the eyepiece with one eye and keep the other eye open (...
PROBLEM TO BE SOLVED: To shorten the time required for focus adjustment of an electron microscope at a plurality of inspection points. SOLUTION: When adjusting the focus according to the height of the surface of the sample at each inspection point in order to continuously inspect multiple ...
Look at the side of the microscope and turn the Adjustment knob until the lens is very close to, but not touching, the slide. Look through the eyepiece and move the Adjustment knob so that the lens lifts away from the slide. The image should come into focus. Be careful not to drop ...

Never use force when focusing the microscope. If the focus knob is tight and will not rotate it is because it is locked, the tension needs to be adjusted, or it is running into an objective lens. When you first look through the microscope, you may need to adjust the rheostat light cont...
