I-achromatic waveplates ngokusebenzisa iziqwenga ezibini zeepleyiti.Iyafana ne-Zero-odolo ye-waveplate ngaphandle kokuba amacwecwe amabini enziwe ngezinto ezahlukeneyo, ezifana nekristale quartz kunye ne-magnesium fluoride.Ekubeni ukusasazwa kwe-birefringence kunokwahluka kwizinto ezimbini, kunokwenzeka ukucacisa amaxabiso okubuyiswa kwinqanaba le-wavelength.
