Abstract

We report on an expanded catalog1–4 of various common (and uncommon) black and white materials used in the construction and/or baffling of optical systems and as screen material for calibration systems. Total reflectance is measured over a broad wavelength range (250 nm < λ < 2500 nm) that is applicable to ultraviolet, visible, and near-infrared instrumentation. Reflectivity data for the complete sample inventory will be available via Filtergraph, an online data visualization tool.
