Specifications of Waveplate
-
Retardance
Quarter-wave plate (λ/4): Introduces a phase difference of one-quarter wavelength (π/2) between the fast and slow axes. This is commonly used to convert linearly polarized light into circularly polarized light.
Half-wave plate (λ/2): Introduces a phase difference of one-half wavelength (π) between the fast and slow axes. This is often used to rotate the plane of linearly polarized light.
-
Material
The material of the waveplate determines its birefringence (the difference in refractive index for different polarizations) and operating wavelength range. Common materials include quartz, calcite, and polymer films.
-
Waveplate Order
This refers to the number of wavelengths of phase difference introduced by the waveplate. Zero-order waveplates offer the most consistent performance across a wider wavelength range, while multi-order waveplates are generally more affordable but have a higher dependence on wavelength.
-
Design Wavelength (DWL)
This specifies the wavelength for which the waveplate is designed to introduce the desired phase difference. Performance can deviate slightly at wavelengths further away from the center wavelength.
-
Retardance Tolerance
This indicates the allowed variation in the introduced phase difference across the waveplate. Higher tolerance ensures more consistent performance.
Waveplate Input and Output
Quarter-Wave Plate (λ/4):
Input: Linearly polarized light
Output: Circularly polarized light
This type of waveplate converts linearly polarized light into circularly polarized light.
Half-Wave Plate (λ/2):
Input: Linearly polarized light
Output: Rotated linearly polarized light (by 90 degrees)
Half-wave plates rotate the plane of linearly polarized light by 90 degrees.
While the above describes the behavior for linearly polarized light input, half-wave plates can also be used with circularly polarized light:
Input: Circularly polarized light
Output: Linearly polarized light (depends on the initial circular polarization state)
However, the resulting linear polarization state after using a half-wave plate with circularly polarized light depends on the original handedness (right or left) of the circular polarization.
