Multi Order Half Wave Plate
Price range: ₹19,000.00 through ₹25,000.00
Multi-Order Half-Wave Plate: A waveplate that provides a half-wave phase retardation plus one or more complete 2Ï€ phase cycles, designed for a specific wavelength. It is generally more economical than a zero-order waveplate.
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.
