BASIC
POLARIZED LIGHT MICROSCOPY TERMINOLOGY
COMPENSATORS
& RETARDATION PLATES
Polarized
Light microscopy is a useful tool for distinguishing between singly refracting
(optically
isotropic) and doubly refracting (optically anisotropic) material. Quantitative
measurements
of optical anisotrophy is used in the optical analysis of doubly refracting
or
birefringent
materials under polarized light. These measurements are made with the aid
of
accessory
plates called compensators and retardation plates. Retardation plates have
a fixed
optical
path difference and compensators have a variable optical path difference.
The
intermediate
tube of the Meiji polarized light microscope houses either sliding or rotatable
analyzer,
a sliding Bertrand lens and a slot for insertation of retardation plates
and
compensators.
The dimensions of the compensator/retardation plate are DIN standard
20mm
X 6mm.
QUARTER
WAVE-PLATE - The quarter wave length retardation plate is a thin slice
of
birefringent
material (e.g. mica) cut to a thickness to give 1/4 
optical path difference (OPD)
in
yellow light of about 145nm. The quarter wave-plate changes linear or plane
polarized
light
into circularly polarized light. The quarter wave-plate is useful for qualitative
analysis of
orthoscopic
and conescopic images. The quarter wave plate is also used for assessment
of
optical
path differences in birefringent specimens. 1/4
plate 145nm
FIRST
ORDER RED PLATE - The first order retardation plate is a thin slice
of birefringent
material
(e.g. gypsum) cut to a thickness to give 1
optical path difference (OPD) for green
light.
The first order red plate is frequently used to determine the optical sign
(positive or
negative)
of a birefrigent specimen and is also utilized for contrast enhancement
in weakly
birefringent
specimens. The first order red plate produces an interference color having
a
typical
tint of the first order red. The first order red plate is known by several
names, including:
gypsum
plate, lambda plate, sensitive tint plate, and full wave plate. 1
plate = 550nm
QUARTZ
WEDGE - The quartz wedge is a variable compensator which is designed
to
produce
a range of retardation values as the wedge is moved in and out of the optical
path.
The
thin edge of the wedge produces an optical path difference of zero. The
optical path
difference
increases with increasing thickness of the wedge. Each separate wavelength
in the
spectrum
produces a series of dark extinction bands of which the OPD is exactly
one
wavelength
apart. Specimen retardation values can be determined by observing changes
in
the
polarization properties of birefringent specimens as the wedge thickness
in the light path
varies.
Meijis quartz wedge permits retardation measurements from 1-6 wavelengths.
SENARMONT
COMPENSATOR - The Senarmont compensator is useful tool for
measurement
of retardation levels of crystals, living organisms and also for measuring
permanent
stresses in clear materials. The Senarmont compensator is also used for
image
contrast
enhancement of weakly birefringent specimens.
ANALYZER
- A polar place in the light path after the specimen. The analyzer is removable
from
the light path and may be rotatable. The analyzer is used to determine
the optical effects
produced
by the specimen either in plane or polarized light.
BERTRAND
LENS - The Bertrand lens is located above the analyzer. The eyepiece
and
Bertrand
lens act as a system to focus on the back image plane of the objective.
The Bertrand
lens
main function is to view interference figures (conoscopic images) which
appear in the
back
image plane of the objective when the specimen is viewed between crossed
polars
using
highly convergent light from the condenser.
BIREFRINGENCE
- A quantitative expression of the separation of a light beam as it
penetrates
a doubly refracting object into two diverging beams..
CONOSCOPIC
FIGURE - A pattern consisting of isogyres and/or isochromatic curves
formed
in the back image plane of the objective also referred to as an interference
figure.
CONOSCOPIC
OBSERVATION - Observation of the conoscopic or interference figure
by
means
of a Bertrand lens.
PLANE-POLARIZED
LIGHT - Light with only one vibration direction present.
PLEOCHROISM
- A property exhibited by certain crystals of absorbing selectively various
wavelengths
of light and of displaying different colors when looked at in the directions
of their
various
crystal axes.
POLAR
- A device which produces plane polarized light from natural light.
POLARIZER
- A polar placed in the light path before the specimen.
STRAIN
FREE - A term used to signify that microscope objectives and condenser
lenses
are
selected to have a minimum amount of internal stress in the glass. Strain
free optics offers
little
or no contribution to the optical path difference of the specimen.
