MICROSCOPE Flashcards
an optical device used in examining microscopic
structures.
microscope
The first simple microscope was first used by
Anton Van Leeuwenhoek
Total magnification formula
objective lens • ocular lens
it is the number of times which specimen is enlarge
magnification
The objective lens is also known as
primary magnifier
The ocular lens is also known as
secondary magnifier
- it is where the microscopic slides which contain the specimen
placed
Stage
- it concentrates the lights
Condenser
- it gives the sharper specimen
Focusing Knobs
- it serves as the source of illumination
Light
the ability of the lenses to distinguish two points.
resolution
uses a metal probe to scan a
specimen.
Scanning-Probe Microscopy
Uses electrons instead of light.
electron microscopy
Uses fluorochromes and a laser light.
confocal microscopy
Uses UV light.
Fluorescence Microscopy
it gives us the general view of the specimen
LPO
both detailed the examination
HPO and OIL
the light bending ability of a medium.
refractive index
used to keep light from bending
immersion
the artificial coloring in the specimen
staining
Accentuates diffraction of the light
that passes through a specimen.
