|
Resolution |
is the ability to see and distinguish finer details |
|
|
Parfocal |
is when the specimen is in focus with one objective, then when changing from one objective to another, the specimen will almost be in focus |
|
|
Contrast |
is the degree to which an image details stand out against their backgrounds |
|
|
Field of view |
is the area within the eyepiece. It decreases with increasing magnification |
|
|
Parcentral |
is when the specimen is in the center of the eyepiece viewing area with one objective, and then the specimen will almost be in the center with the next higher objective |
|
|
Depth of Field |
is the focal length with viewing a specimen. It decrease then there is increasing magnification ie:camera focuses/zooms in on hero or couple kissing |
|
|
Magnification |
is the increase in apparent size of an object |
|
|
Magnification Vs Resolution |
(.. vs 00) the ability to see two dots as separate dots is magnification with good resolution (.. vs **) is magnification with poor resolution |
|
|
Eyepiece |
(10X) magnifies 10 times |
|
|
Objective |
(4X-red, 10X-yellow, 40X-blue) 100x-white, oil immersion( do not use) |
|
|
Stage |
Specimen is placed on |
|
|
Specimen holder |
spring loaded clamp to hold slide in place, DO NOT LIFT UP |
|
|
Coarse adjustment knob |
Use for 4X objective only. Major change in focus |
|
|
Fine Adjustment Knob |

|
|
Iris diaghragm lever |
opens/closes iris diaphragm to adjust contrast |
|
|
Condenser |
focuses light on specimen |
|
|
condenser height adjustment knob |
moves condenser to focus light on specimen |
|
|
Rheostat |

linking many monomers together by a covalent bond |
|
|
dehydration synthesis |
(removal of water) process by which monomers are linked together |
|
|
Hydrolysis |
breaking covalent bonds by the addition of water |
