I-spectrometer ye-LED isetshenziselwa ukuthola i-CCT (izinga lokushisa lombala elihlobene), i-CRI (inkomba enikeza umbala), i-LUX (i-illuminance), kanye ne-λP (i-main peak wavelength) yomthombo wokukhanya we-LED, futhi ingabonisa igrafu yokusabalalisa i-spectrum yamandla, I-CIE 1931 x,y chromaticity coordinate grafu, CIE1976 u',v' xhumanisa imephu.
I-interating sphere iyi-cavity sphere embozwe ngento ekhanyayo emhlophe ehlakazekile odongeni olungaphakathi, eyaziwa nangokuthi i-photometric sphere, i-luminous sphere, njll. Imbobo yewindi elilodwa noma amaningana avulwa odongeni oluyindilinga, asetshenziswa njengendawo yokungena ukukhanya. izimbobo nezimbobo zokwamukela zokubeka amadivaysi okwamukela ukukhanya. Udonga lwangaphakathi lwendilinga ehlanganisayo kufanele lube indawo eyindilinga enhle, futhi ngokuvamile kuyadingeka ukuthi ukuchezuka endaweni eyindilinga efanelekile akufanele kube kukhulu kuno-0.2% wobubanzi bangaphakathi. Udonga lwangaphakathi lwebhola lumbozwe nge-diffuse reflection material ekahle, okungukuthi, into ene-diffuse reflection coefficient eseduze no-1. Izinto ezisetshenziswa kakhulu yi-magnesium oxide noma i-barium sulfate. Ngemuva kokuyixuba nge-adhesive colloidal, fafaza odongeni lwangaphakathi. Ukubukeka kwe-spectral kwe-magnesium oxide enamathela ku-spectrum ebonakalayo kungaphezu kwama-99%. Ngale ndlela, ukukhanya okungena endaweni ehlanganisayo kubonakala izikhathi eziningi ngodonga lwangaphakathi olunodonga ukuze kwakhe ukukhanya okufanayo odongeni lwangaphakathi. Ukuze uthole ukunemba okuphezulu kokulinganisa, isilinganiso sokuvula se-sphere ehlanganisayo kufanele sibe sincane ngangokunokwenzeka. Isilinganiso sokuvula sichazwa njengesilinganiso sendawo ye-sphere ekuvuleni kwe-sphere ehlanganisayo endaweni yalo lonke udonga lwangaphakathi lwe-sphere.
