Camere per Spettroscopia NIR
Camere Serie iDus InGaAs da Oxford Instruments AndorSulla base della piattaforma delle camere iDus, la Oxford Oxford Instruments Andor offre soluzioni con detector lineari InGaAs per applicazioni di Spettroscopia nel range NIR fino a 1.7 µm o 2.2 µm.
Le camere iDus InGaAs 490 e 491 sono dotate rispettivamente di un array di fotodiodi (PDA) da 512 e 1024 pixels con pixel size da 25x500 µm mentre la camera iDus InGaAs 492 monta un sensore da 512 pixel con pixel size da 50x500 µm.
Le iDus InGaAs possono essere impiegate come rilevatori stand-alone o accoppiate ad uno spettrografo od un monocromatore.
Maggiori informazioni
Le camere iDus InGaAs sono dotate di sistema di raffreddamento termoelettrico in grado di raggiungere una temperatura minima di -90°C con conseguente ottimizzazione del rapporto segnale/rumore. In queste condizioni la dark current diventa trascurabile senza necessità di impiego di sistemi ad Azoto liquido (LN2). A temperature inferiori, infatti, la dark current diminuirebbe in modo ininfluente rispetto alla perdita di efficienza quantica che si avrebbe alla stessa temperatura e pertanto il risultato equivarrebbe ad un peggioramento in termini di rapporto segnale/rumore.
Interfacciando le camere Andor Serie iDus InGaAs agli spettrografi Czerny-Turner Andor Serie Shamrock, nella versione con ottiche con coating in argento, è possibile ottenere sistemi per Spettroscopia ad alto rendimento ed ottimizzati per il range NIR.
