Spettrometro UV-Vis-NIR a doppio raggio, equipaggiato con sfera d’integrazione di 150 mm di diametro che consente la misura della riflettanza e trasmittanza spettrale di materiali regolari e diffondenti fra 250 e 2500 nanometri, oppure con detector 2-D per la caratterizzazione di materiali regolari e liquidi fra 200 e 3300 nanometri.
Caratteristiche tecniche
Spettrometro con spettrofotometro a doppio raggio con doppio monocromatore e registrazione del rapporto, dotato di sistema ottico interamente riflettente con rivestimento in SiO₂ e monocromatori a reticolo olografico in configurazione Littrow. Rivelatore fotomoltiplicatore per UV/Vis e PbS con controllo Peltier per NIR. Offre risoluzione ≤0,05 nm in UV/Vis e ≤0,20 nm in NIR, luce diffusa a 220 nm ≤0,00007 %T e intervallo fotometrico fino a 8 A.
