Bk7 reflectance standard
WebIf the thickness of the V-coat layers is incorrect, the reflectivity of the coating increases and the DWL changes. V-coats from Edmund Optics typically achieve minimum reflectivities significantly less than 0.25%, but all standard V-coats have specified reflectivities of … WebFor example, N-BK7 (Schott glass) has a bulk absorption coefficient of about 0.0024 cm-1. When you think about reflectance in this way, converting between transmittance and reflectance is rather ...

WebJul 25, 2013 · These diffuse reflectors are produced from an N-BK7 substrate and are available in 120, 220, 600, and 1500 grit polishes. Polished diffusers are advantageous over sand blasted diffusers as the surface has greater uniformity. The various grits provide a range of reflected intensity distributions. http://www.glassdynamicsllc.com/BK7%20Material%20Data%20Sheet.htm
