Frequently Asked Questions

A Multiple Order Half Waveplate is a type of waveplate that is sensitive to changes in temperature, angle of incidence, and degree of collimation. It is intended for use at the design wavelength only.

The features of the Multiple Order Half Waveplate include quarter and half waveplates, zero or multiple order available.

A Quarter Waveplate is used to convert linearly polarized beams into circularly polarized beams (and vice versa), while a Half Waveplate introduces a 90° rotation of the plane of polarization.

The applications of Half Waveplates include rotating the plane of polarization (e.g. in a laser), electro-optic modulation, and as a variable ratio beamsplitter (when used in conjunction with a polarizing cube).

If used at a different wavelength, a retardation change of 10% occurs for every 0.2 nm deviation.
