Schneider polarization filters are constructed with
dichroic sheets of laminated polymers that are ce-
mented between protective glasses. Natural light and
many artificial light sources used for illumination emit
unpolarized light or at least light with a low degree of
polarization. If light goes through a linear polarizer it
will afterwards be linearly polarized in the orienta-
tion of the polarization axis of the filter. When using
a circular polarizer, light will be either left or right
circular polarized. A circular polarizer consists of a
linear polarizer combined with a lambda/4 element at
an angle of 45°. If a pair of corresponding polarizers

is used (linear with linear or circular with circular),
light passes when the orientation of their polariza-
tion axis is parallel. Light is blocked if the orientation
is orthogonal to each other – this means for linear
polarizers perpendicular polarization axes and for
circular polarizer, left circular combined with right
circular (or vice versa). In imaging applications, this
effect is used to efficiently suppress reflections on
dielectric or metallic surfaces because the reflected
light is partially polarized (depending on material and
reflective angle) and will be blocked if the filter is
rotated in the appropriate orientation.
