What is the function of the codenser lens in the compound light microscope?
The function of a condenser lens is to focus the light onto a specimen. Condenser lenses are most useful at the highest powers of 400 x and above. Microscopes with a condenser lens render a sharper image than those with no lens. These lenses are able to move up and down.
What are the light source of the microscope for?
to generate light, so the specimen can be examined (sends light through base, diaphragm, stage specimen, slide, objective lens, nose-piece, body, body tube, and eyepiece)
Compare the functions of the objective lens in a telescope and a microscope?
The objective lens in a microscope is mainly used to magnify an object. In a telescope, the objective lens is mainly used to gather light.
What is a coverslip?
A cover slip is a very thin piece of glass used to cover a sample on a microscope slide. It stops the sample from getting on to the objective lens of the microscope.
When should you use scanning lens on the microscope?
The scanning lens of a compound microscope is used whenever a new slide is viewed or when the view of the specimen in the field of a higher power lens is lost. Think of it as the "neutral" position for the lens array. The scanning lens has the greatest working distance of the lens group on the microscope and is far enough away from the slide to avoid crunching the slide (and possibly damaging the lens) when attempting to focus. Many microscopes are parfocal, meaning that once you have a focused view of the specimen with the scan lens the image will be in, or very near in, focus when you swivel to a higher power lens. Very important! If you can't find a good view at higher power, or you "lose" the specimen after trying to focus with the fine focus knob only, go back to the scanner lens. Never use the coarse focus with anything but the scanner lens in position. Not doing this is probably the number one reason slides get crunched. And everyone will know because it usually makes an unmistakable sound that reverberates all over the lab.
Lens used to locate specimen on a microscope?
low power objective! :)
What is the lens used to locate the specimen on the Microscope And yes Im working on the crossword ws?
im working on the same worksheet too, its lowpowerobjective :D
Lens used to locate the specimen?
lowpowerobjective
What lens is used to locate the specimen?
fartlick is your new name
What does a fine focus do on a microscope?
This allows for small adjustments to the focus. Usually the large focus is used with smaller powers (not zoomed in as much), to locate the specimen and move it closer (or further away) from the lens. The fine focus knob is used once the specimen is almost in focus, or if you are on high power.
Part of the microscope that is used to increase the amount of light passing through the specimen?
The part of the microscope is called the Condenser
Concentrates light onto the specimen?
The mirror, which can also be called the light source. It reflects the light.
What is the lens that is used to find the specimen on a microscope?
You use the low power lens to find the specimen with a microscope. Once you have found the specimen on low power, you can switch to high power for greater magnification. Just be sure to use only the fine adjustment knobs for focusing on high power so the high power objective won't hit the slide.
Oil immersion is used as a medium between the specimen and the oil immersion objective lens why?
Oil immersion is a technique used to increase the resolution of a microscope.
What is the objective lens used to locate the specimen and the first focus?
When viewing a specimen, you must always use the lower power objective lenses first. Low power lens gives the widest field of view and makes it easier to find the specimen when you look through the microscope. Finding the specimen at high power, without first centering it in the field of view at low power, is nearly impossible.
Uses lenses to magnify a specimen what can be used to view living cells is called?
A light microscope uses lens to see living cells.
What are the differences between a microscope and a hand lens?
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.
