Abstract
Inventia se refera la un filtru de sticla colorat în masa cu coloranti ionici (compusi de Vr si Mn), care absoarbe radiatiile din domeniul vizibil si transmite pe cele din domeniul infrarosu apropiat, precum si la un procedeu de realizare a acestuia. Acest filtru se utilizeaza la aparatura de observare pe timp de noapte si prezinta avantajele unei reproductibilitati usoare a caracteristicilor spectrale de la o sarja la alta, uniformitate a culorii, prelucrabilitate usoara si proprietati fizico-mecanice superioare filtrelor colorate cu Sb si Se.The invention relates to a colored glass filter with ionic dyes (Vr and Mn compounds), which absorbs radiation from the visible field and transmits those in the near-infrared field, as well as to a process for realizing it. This filter is used for night-time observation and has the advantages of a light reproducibility of spectral characteristics from one batch to another, color uniformity, lightweight machinability and superior physical and mechanical properties to Sb and Se stained filters.
