Solfuro di Zinco (ZnS)

Solfuro di Zinco (ZnS)

Il Solfuro di Zinco (ZnS) è un materiale chimico inerte policristallino estremamente puro, realizzato con CVD (Chemical Vapor Deposition) per ottenere una alta trasmittanza nel range 1-14μm. Attraverso un processo di post-deposizione si ottiene dal ZnS standard la versione multi-spettrale.
