37 Cards in this Set

  • Front

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

Minor changes in focus

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

increase/decrease light
