Savart Plate
The
device is used to transmit polarized light and form interference fringes
of the light, thus indicating its presence. It consists of two calcite
plates of equal thickness, cut parallel to their natural cleavage faces
and rotated and cemented together so that one is at right angle to the
other.
It is usually used in combination with an analyzer. |
