Conclusions
The n
γ
-direction of the
λ
-compensator is NE-SW oriented. The environment of the fiber exhibits a dark,
first-order red (path difference is one
λ
; approx. 550 nm). The fiber itself appears greenish blue (path
difference approx. 700 nm). The higher interference color (700 nm) can only have been created by
addition of the path differences of the object (approx. 150 nm) and that of the
λ
-compensator (approx.
550 nm), while the lower one (approx. 400 nm) must have been created by subtraction.
Addition is possible if n
γ
of the compensator and n
γ
'
of the object are parallel. Therefore, n
γ
'
of the object
also lies in NE-SW direction in the case of a higher interference color and is oriented parallel to the
longitudinal axis of the fiber.
Summary
Compare the interference colors (path differences) in the two diagonal positions. The higher path
difference results if both n
γ
-directions are parallel, which defines the n
γ
'
-direction of the object.
☞
If the thickness of the specimen is known or can be measured, the MICHEL LEVY color chart
can be used to determine the birefringence
∆
n
γ
of minerals, synthetic crystals, polymers,
strained glass, biocrystals or erythrocytes; starting at the intersection point of the
Γ
-value and
of the thickness d, the inclined line is followed to the outside right up to the edge of the chart.
