Objectives
Aperture Iris Diaphragm (on the condenser)
10 power
oculars, objectives, condeser, lenses in the body tube
bulb, camel hair brush, lens cleaner, lens paper
Centering Screws
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
Optimal Illumination
Condenser
A kimwipe or kleenex scratches optical parts
The objective projects a flat image on the entire field of view.
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
Parcentric: specimen stay in field of view when magnification is increased
Parfocal: specimen stays almost in focus when magnification is increased
Go back to 10X objective & repeat the process of finding & clearly focussing with coarse adjustment
slide upside down, objective not screwed in place
Aperture Iris Diaphragm Control or Reo-stat/Light Intensity Knob
10, 40,100
magnification, resolution, contrast
Resolution : the microsopes ability to separte small details crisp and clear
Contrast: the specimen against the background
ex. dark against light
Rotating head, mechanical body tube, stage, rotating nosepiece, arm, coarse & fine adjustment, base, light source
