Zero Order Half Wave Plate
₹25,000.00
Zero-Order Half-Wave Plates are built by combining two Multi-Order Crystalline Quartz Wave Plates to obtain an optical path length difference of λ/2.
A half-wave plate is a birefringent material which changes the phase between two perpendicular  polarizations. A half-waveplate is very helpful in rotating the plane of polarization from a polarized laser to any other desired plane (especially if the laser is too large to rotate). Most large ion lasers are vertically polarized, for example, so to obtain horizontal polarization, simply place a half-waveplate in the beam with its fast (or slow) axis 45° to the vertical.
