Product Description

The Sloan Digital Sky Survery (SDSS) photometric system is the most common filter set used by observatory today. Antlia Photometric Sloan filter set includes four filters covering 400nm to the sensitivity limit of silicon CCD cameras near 1100nm.

Ion Gun Assisted Deposition coating technology on the double-sided polished substrate makes them the most consistent, durable and accurate filters. Antlia Sloan filters have almost total suppression of optical density (OD)5, the result is that our photometric sloan filters minimize the already small leakage and create a superior contrast.
