Abbes law

The minimum resolving distance is related to the wavelength of light divided by the numerical aperture, which is proportional to the angle of the light cone formed by a point on the object, to the objective

1

In phase .... Amplitude
Out if phase .... Amplitude

Increases
Decreases

2

Components of a microscope

Recording system
Eyepiece
Objective lenses
Specimen stage
Condenser lense
Light source
Epi-illumination source

3

Types of electron microscopes

TEM = transmission electron microscope (thin)
SEM = scanning electron microscope (bulk)

4

Role of the condenser lens

Focuses light onto the specimen
Fills the objective lens

5

Describe kohler illumination

Creates an evenly illuminated field view while illuminating the specimen with a very wide cone of light

6

How does differential interference contrast work?

Uses a beam splitter
