Polarization analyzer tekanyo ea ho daela qeto: 2 °
Bophahamo ba sebaka sa ho lekanya: 30mm
Polarizer axis ke likhato tse 45; Karolo ea kotara ea leqhubu la mahlaseli a liehang ke likhato tse 45. Analyzer axis ke -45 degree. Mohlala o behiloe lipakeng tsa polarizer le poleiti ea quarter-wave.
Ntle le sampuli, pono e lefifi. Ha khalase e nang le axis e ka sehloohong ea khatello ea maikutlo e kenngoa, ho hlaha fringe e ntšo ea isochromatic, e leng sebaka sa khatello ea zero. Phapang ea tsela ea optical e bakoang ke khatello ea kelello e ka sehloohong e ka lekanyetsoa ka tsela ena: potoloha analyzer ho fihlela 'mala oa tšitiso o nyamela (haeba ho kheloha ha tsela e khanyang ke zero,' mala o motšo). Phapang ea tsela ea optical ea ntlha ea ho lekanya e ka baloa ka sekhahla sa ho potoloha.
