New cards

Total Magnification

equal to the power of the ocular lens multiplied by the power of the objective lens used

ex: 10 (ocular lens) x 45 objective lens

2
New cards

Resolution (Resolving Power)

Ability to discriminate between two close objects as separate

3
New cards

Parfocal

Property of microscope which allows objectives to be changed without having to refocus

Lens that stays in focus when magnification/focal length is changed

4
New cards

Field

Area you see though the microscope

5
New cards

Depth of Field

The thickness of the plane that is clearly in focus

6
New cards

Working Distance

Distance between objective lens and specimen
