Farve Referenser og Spektroskopi Standarder

Farvereferencer og spektroskopistandarder anvendes rutinemæssigt til at overvåge mekanismerne i optiske spektrometre. Kalibreringsopløsningerne giver basisaflæsninger, som brugerne kan sammenligne med de bølgelængder og intensiteter af elektromagnetisk stråling, som de videnskabelige instrumenter registrerer. Ved at placere referenceopløsningen i instrumentet kan brugerne nulstille indstillingerne for at genetablere korrekt mekanik og eliminere systematiske fejl. Til kvalitetskontrol sikrer farvereferencer og spektroskopistandarder, at apparaterne fungerer korrekt og leverer nøjagtige spektrallinjer.
