Alternatively, calibration may be checked using a Polarization Reference Standard, which consists of a plate of quartz mounted in a holder perpendicular to the light path.
或者，校准可以通过使用一个偏振标准品来进行，该标准品由一片装在垂直于右侧通道的架子上的石英构成。

The LC alignment direction is found perpendicular to the polarization axis of the incident LPUV light.
液晶的取向方向垂直于入射LPUV光的偏振轴。

But the size perpendicular to polarization direction of focal spot with linear polarized beam is always smaller than that of radially polarized beam.
