We used the EOM and quarter-wave plate combination to rotate the polarization direction of the linearly polarized laser light. Bile must be centrifuged and examined under polarizing or light microscopy for detection of precipitates. Even though the sun itself produces fully depolarized light, partially linearly polarized light is abundant in natural scenes. 2 [with object] Physics Cause (something) to acquire polarity: the electrode is polarized in aqueous solution...

The S atom in this side chain also helps polarize the C-H bond more than other methyl C-H bonds. 3Divide or cause to divide into two sharply contrasting groups or sets of opinions or beliefs: [no object]: the cultural sphere has polarized into two competing ideological positions...

For those that don't know, in LCD displays, use is made of linear polarisers, familiar to most as the glass in polarising sunglasses. During phosphorescence measurements the polarizers are removed. A linear polarizer placed before the beam splitter rejected the p-polarized light, reducing the light noise and increasing the system dynamic range.
