    The Quarter Wavelength Retardation Plate - Olympus

    The quarter wavelength retardation plate is a common optical accessory for polarized light microscopy that operates by introducing a relative phase shift of 90 degrees between the orthogonal wavefronts (ordinary and extraordinary) passing through when the plate is illuminated with linearly polarized light. Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. This difference in velocities gives rise to a phase difference when the two beams recombine.Crysmit waveplates, including octadic-wave (λ/8), quarter-wave (λ/4), half-wave (λ/2) and full-wave (λ) plates, are widely used in synthesis and analysis of light in various states of polarization.

    Wave plates are suitable for high or low power laser applications. Zero Order Optically Contacted Wave Plates Rotate the direction of polarization (λ/2) or convert linear into circular polarization or vice versa (λ/4). Quarter-wave stubs. Starting with an open circuit, one quarter wavelength away you will "see" a short circuit. Starting from a short circuit, one quarter wave away you have an open circuit. Thus you can create an "RF open circuit" that is a DC short circuit, and vice versa. These two properties are used to create DC and/or RF grounds for ... With this configuration, the relative phase imparted can be, for the case of a half-wave plate, half a wavelength rather than half plus an integer. This is called a zero-order wave plate. Like lenses, wave plates can also be made achromatic by combining materials with different dispersion.

    Quartz Zero-Order Half-Wave Waveplate

    Retardation in zero-order wave plates is insensitive to temperature since thermal changes between the two quartz plates tend to cancel out. A typical zero-order wave plate has a temperature coefficient of 0.0001 λ/°C compared to 0.0015 λ/°C for a multiple-order wave plate, providing less change in retardation over an extended temperature range. Wave Plates and Applications Birefringent wave plates, or retardation plates, are extremely useful for applications where you want to synthesize and analyze light of different polarization states. For example, using a quarter-wave plate, you can convert an input beam from linear polarization to circular (or elliptical) polarization and vice versa.

    High Power Traveling Wave Tube Amplifiers (TWTA), High Voltage Power Systems and Test Equipment for Microwave Tubes. Quarterwave manufactures a complete line of popular Traveling Wave Tube Amplifiers. An ideal quarter wave plate does not absorb any light. The speed of light through the quarter wave depends on the orientation of the electric field vector relative to the plate. So one orientation is slowed down more than the other and the thickness of the plate is designed so that there is a change of phase of $90^\circ$ for one plane relative to another. A half-wave plate (or any arbitrary-wavelength plate) works on the principle of Birefringence, which is that the crystal in question has a different refractive index for a different polarization of light. Most materials that you deal with in basic...

Waveplates – also known as "retardation plates" – are optical elements that create a phase shift in the transmitted light with the help of birefringency crystalline quartz. A phase shift of 90° is referred to as a l/4 plate, quarter wave plate, or a circular polarizer; whereas a phase difference of 180° is referred to as a l/2 or half wave plate.

    The wave plate is then mounted in an anodized aluminum housing. The housing is engraved with a line indicating the orientation of the fast axis of the wave plate, text stating it is a zero-order quarter-wave plate, and the design wavelength. Quarter-wave plates are used to turn plane-polarized light into circularly polarized light and vice versa. To do this, we must orient the wave plate so that equal amounts of fast and slow waves are excited. We may do this by orienting an incident plane-polarized wave at 45° to the fast (or slow) axis, as shown in Figure 4. Waveplate (Wave plate) Waveplate (wave plate, retardation plate or phase shifter) is made from material which exhibit birefringence, the most common waveplate material is crystal quartz.
