Multi-order
Waveplates |
| |
| These multiple order waveplates are
made from a piece of crystal quartz with its optic axis parallel
with the plane of polarization. A quarter wave plate has a net retardation
of (2k + 1) / 2, where k is an integer, and changes polarization
from linear to circular or circular to linear. It will work as a
half wave plate when used in double-pass as in a laser cavity. A
half wave plate has a net retardation of (2k + 1) p, where k is
an integer, and rotates the plane of polarization by 90. Optionally,
these waveplates are available mounted in a metal cell. |
