Waa maxay sababta Refractometry ay muhiim ugu tahay cabbirka cabbirka
Markay timaaddo cabbiridda cabbirrada, maaha oo keliya cabbirka jireed ee shay. Refractometry waa farsamo lagu cabbiro tusmada wax-soo-celinta ee walaxda, taasoo bixin karta macluumaad qiimo leh oo ku saabsan sida ay u samaysan tahay iyo sifadeeda.
Tani waxay si gaar ah faa'iido ugu leedahay ellipsometry, halkaas oo dhumucda iyo sifooyinka indhaha ee filimada khafiifka ah lagu qiyaaso.
Isticmaalka refractometry, waxaan si fiican u fahmi karnaa habdhaqanka iftiinka marka uu la falgalo filimadan, taas oo u oggolaanaysa cabbirro sax ah oo sax ah.
Marka, in kasta oo ay u ekaan karto farsamo dahsoon, refractometry ayaa door muhiim ah ka ciyaara adduunka cabbirka cabbirka.
