Description du produit
Le système photométrique Sloan Digital Sky Survey (SDSS) est le jeu de filtres le plus couramment utilisé par les observatoires aujourd'hui. Le jeu de filtres photométriques Sloan d'Antlia comprend quatre filtres couvrant 400 nm jusqu'à la limite de sensibilité des caméras CCD au silicium près de 1100 nm.
La technologie de revêtement par dépôt assisté par canon ionique sur le substrat poli double face en fait les filtres les plus cohérents, durables et précis. Les filtres Antlia Sloan ont une suppression presque totale de la densité optique (OD)5, le résultat est que nos filtres photométriques Sloan minimisent les fuites déjà faibles et créent un contraste supérieur.
