Frequently Asked Questions

The Ealing Multiple Order Waveplates are used to rotate the plane of polarization in a laser, electro-optic modulation, and as a variable ratio beamsplitter.

The Ealing Multiple Order Waveplates have quarter and half waveplates, zero or multiple order available.

Waveplates are made from materials that exhibit birefringence.

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

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