Similar to the [transmissive polariscope](/transmission-photoelasticity), both the *polarizer* and the *analyzer* should be circular polarizers. In assembling the circular polarizers, it is important for the principle axis of the quarter-wave plate to make a $`45^{\circ}`$ angle with the direction of polarization of the linear polarizer. Note that for a darkfield polariscope, the analyzer must match the chirality of the polarizer on the incident light path (see section 2. for mathematical proof), and can even be the same optical element. For a brightfield polariscope, the two polarizers are complementary.
