microscope Flashcards
(25 cards)
refers to the main section of the microscope, minus the stand (base) or any illuminators.
generally include the eyepiece and objective lenses, but not the focusing block.
body
These lenses, also known as ocular lenses, are typically 10X, but also come in 5X, 15X and 20X varieties. is what you actually look through to see your specimen. The interocular distance is adjustable so that you can keep both eyes open when looking into the microscope.
eyepiece lens
is the area of the microscope between the tube and the base. To carry a microscope, grip the arm with one hand and place the other hand underneath the base.
arm
called a revolving nosepiece or turret, this structure holds the objective lenses. Rotating it allows the objective lens to be switched.
Nosepiece
lens closest to the object being viewed is known as. has a different magnification, including the scanning lens (4X), low-power lens (10X), mid-power lens (40X), and high-power lens (100X)
objective lens
Controls the power to the microscope
on/off switch
This area is the main, flat surface that holds the slides for observation
stage
Most useful at higher powers, is typically a five-hole disc housed under the stage that adjusts the amount of light passing through the stage opening. Each opening is a different diameter controlling how much light passes through to help properly illuminate the specimen while also increasing contrast and resolution.
diaphragm
The mechanical stage allows for adjustment of the slide position forward, backward, and left or right.
stage adjustment knob
The larger of two adjustment knobs that moves the objective lenses closer to, or farther away from, the specimen in large steps.
coarse focus
The smaller of two adjustment knobs moves the objective lens closer to, or farther away from, the specimen in very small steps. It can be used to fine-tune the focus on various parts of a specimen after first using the Coarse Focus to get close.
fine focus
the bottom support structure of the microscope. To carry a microscope,
base
brand of specialty paper-based cleaning wipes suited for cleaning laboratory equipment and instruments,
kimwipes
rectangular plate, made of either plastic or glass, is used to hold the specimen. In some cases, it may also contain a depression or well to hold several drops of liquid
slide
several drops of liquid.
You sent
used exclusively with a 100X or higher objective lens, typically at 1000X total power. A drop of oil is placed on the cover slip with the objective lens lowered until it touches the drop. Acting as a bridge between the glass lens and the glass slide, the oil concentrates the path of light to increase the resolution of the image
immersion oil
special paper cleaning material is specifically designed to be used for cleaning lenses and other glass components without introducing scratches to the surface. It is especially useful for cleaning microscopes and other sensitive laboratory equipment, as well as cameras, telescopes, glasses, etc.
