СПОСОБ ОПРЕДЕЛЕНИЯ СПЕКТРАЛЬНОЙ ЗАВИСИМОСТИ КОЭФФИЦИЕНТА ОТРАЖЕНИЯ ТОНКОПЛЕНОЧНЫХ ПОКРЫТИЙ

摘要

FIELD: measuring technique. ^ SUBSTANCE: method comprises comparing the specimen with unknown reflection coefficient with a standard having known reflection coefficient by means of an auxiliary arrangement for the spectrophotometer. The measurements of the reflection coefficient that is less than 20% are performed with the use of a standard that is made of a plate with black back side made of an optical glass with known reflection coefficient. To measure a more than 20% reflection coefficient, a standard is made of a mirror with outer reflecting chromic layer. ^ EFFECT: enhanced precision. ^ 3 dwg
