Electron Microscope
Field of view ^-^ Field of view >.< xD
first view with low power then gradually increase the power. hope it helped you!
start by focusing with the lowest lens to make sure the slide is right and you can see the specimen them proceed to the next lens power and focus again just to make the view clear then proceed to the highest and focus one more time
An optical microscope uses light and one or more lenses to view cells. An optical microscope with two or more lenses is called a compound optical microscope.
When viewing a specimen through a hand lens, you can see in slightly greater detail than your naked eye, but you may not be able to see micro organisms. With a microscope, you can see things in MUCH greater detail, and you can see micro organisms. With a hand lens, you cannot change the power of magnification, while with a microscope, you can change the power of the magnification. With a hand lens, only one lens is used to magnify an object, while a compound microscope uses two lenses (one in objective lens, one in eyepiece). With a hand lens, you can view a specimen from far away, while an objective lens has to be fairly close to a specimen in order to view it clearly. With a hand lens, you can simply move your hand forward, or backward, to focus on an object. With a microscope, a very complex mechanism is used in order to portray some sort of depth while viewing. This is adjusted by using a coarse, and a fine adjustment knob.
The light microscope and the electron microscope refers to the type of microscope that is used to view the non- living specimen. The non-living specimen is usually placed in a slide.
The visibility of the specimen decreases as the power of magnification increases on a microscope. The specimen area will shrink as the magnification is increased.
Field of view
stereomicroscope
A binocular microscope, which is commonly called a dissecting scope.
the same way as under low-power on a microscope: carefully
if you are reffering to field of view, its not exactly the amount of specimen, its mainly used to determine how large a specimen is
The light microscope and the electron microscope refers to the type of microscope that is used to view the non- living specimen. The non-living specimen is usually placed in a slide.
== == You put a specimen on a glass plate and then view the specimen under a microscope. It acts sort of like a slide.
It allows one to tilt the upper part of the microscope so that you can view the specimen while seated.
A scanning electron microscope has a very large depth of field which makes the images produced appear three dimensional. Magnifications from 25X to 250,000X (250 times the magnification limit of a light microscope) are possible. Although my Science Text book says it can reach a magnification of 300 000X, but most specimens are easier to view at magnification less than 10 000X.
It will enable you to see the specimen as accurately as possible - and change the microscope to view certain elements more clearly.
