Multiple Order Waveplates

Multiple Order waveplates 1.material:Crystal Quartz 2.Dimension Tolerance: +0.0, -0.2 mm 3.Wavelength Range: 400-2100 nm

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) π / 2, where k is an integer, and changes polarizationfrom 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) π, where k is an integer, and rotates the plane of polarization by 90°.Optionally, these waveplates are available mounted in a metal cell.
