Centering Screws
magnification, resolution, contrast
Resolution : the microsopes ability to separte small details crisp and clear
Contrast: the specimen against the background
ex. dark against light
Contaminated/fungal growth
Objectives
Aperture Iris Diaphragm (on the condenser)
oculars, objectives, condeser, lenses in the body tube
Aperture Iris Diaphragm Control or Reo-stat/Light Intensity Knob
Rotating head, mechanical body tube, stage, rotating nosepiece, arm, coarse & fine adjustment, base, light source
Optimal Illumination
10, 40,100
Condenser
Go back to 10X objective & repeat the process of finding & clearly focussing with coarse adjustment
The amount of lighting will be altered.
A kimwipe or kleenex scratches optical parts
bulb, camel hair brush, lens cleaner, lens paper
10 X 100= 1000X TM
The objective projects a flat image on the entire field of view.
slide upside down, objective not screwed in place
Parcentric: specimen stay in field of view when magnification is increased
Parfocal: specimen stays almost in focus when magnification is increased
It increases or gets better
a. Condenser is driven (moved) to its highest point
b. When you close the field iris diagram the cone of light has crisp edges
c. When you remove the right eyepiece the light consumes 66% of the area
Decreases
Objectives not parfocal; slide is upside down; rotate the fine focus adjustment knob in the opposite direction
Return to 10X & refocus w/ coarse adjustment knob then increase maginification
