Sentence examples for wave plate at from inspiring English sources

In particular, the beam is left- and right-circularly polarized after quarter-wave plate at φ = 45° and −45°, respectively.
A quarter-wave plate at wavelength of 1.55 μm has been realized through an optimized design, in which the variation of less than 2% of the phase difference between the two orthogonal components can be obtained in an ultra-wide wavelength range of about 110 nm.
Rotating the quarter-wave plate at a fixed position with respect to the linear polariser, left- or right-handed circularly polarised light was selected.
Experimental results show that the linearly polarized terahertz wave converts into circularly polarized when transmitting through the fabricated quarter wave plate placed at 45°.
In the sample arm, the linearly polarized light is incident on a quarter wave plate oriented at 45° yielding light incident on the sample that is circularly polarized.
The Raman signals obtained with the half wave plate were rotated at 170° with a confocal hole set at 1100 μm and the slit set at 300 μm.
To produce right- and left-handed circularly polarised light, the optical axis of the wave plate was oriented at −45° or +45° relative to the optical axis of the linear polarisation filter.
It traverses a quarter wave plate (QWP) oriented at 22.5° to the slow axis.
In the reference arm the light passes a quarter wave plate (QWP) oriented at 22.5°, a prism pair, which is used to compensate the dispersion mismatch between sample and reference arm and is reflected by a mirror which is mounted on a motorized stage to control the coherence gate position.
