Components
All modern optical microscopes designed for viewing samples by transmitted light share the same basic components of the light path, listed here in the order the light travels through them: In addition the vast majority of microscopes have the same 'structural' components:
- Ocular lens (eyepiece) (1)
- Objective turret or Revolver or Revolving nose piece (to hold multiple objective lenses) (2)
- Objective (3)
- Focus wheel to move the stage (4 – coarse adjustment, 5 – fine adjustment)
- Frame (6)
- Light source, a light or a mirror (7)
- Diaphragm and condenser lens (8)
- Stage (to hold the sample) (9)
These entries are numbered according to the image on the right.

Famous quotes containing the word components:
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
