Analytical Light Microscopy

Question 1

Analytical microscopy means:

Answer 1

The addition of any compositional or material analysis instrumentation to an existing microscope; the combination of instrumentation expands its capabilities from observation to separation and identification of constituent components, be it elemental (with energy or wavelength dispersive spectrometry) atomic (as with back scattered electron images) or structural (crystallography).

Question 2

Stereo microscope is:

Answer 2

A microscope that provides a stereoscope view of a sample.

Question 3

Compound microscope is:

Answer 3

A microscope that uses a combination of lenses to increase final magnification and improve image resolution.

Question 4

Brightfield microscopy is:

Answer 4

Viewing a sample with light that is transmitted through it, typically, on a compound microscope.

Question 5

Fluorescence is:

Answer 5

The luminescence of a sample that persists as long as the sample is excited by radiation (light) of high enough wavelength.

Question 6

Phase Contrast microscopy is:

Answer 6

Viewing a sample on a compound microscope that has been fitted with special optics (silver rings and disks) to translate phase difference into amplitude that provides analytical information.

Question 7

Polarizing Light microscopy is:

Answer 7

Viewing a sample on a compound microscope that has been fitted with special filters that orient the light rays providing analytical information about the sample.
