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 … WebWe plan to measure the reflectance of AR coatings on BK7 substrates over the CIE color range 380-780 nm. Since previous experience indicates that best accuracy is obtained if we scan an uncoated substrate (ground second surface) at the start of each measurement series, we enter Scannext to Reference.

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 ... WebN-BK7 is a very pure universal optical glass made by SCHOTT. It is one of the most common standard glass types used to produce high-quality optics, mainly for the visible spectrum. The relatively hard borosilicate crown material consists of the purest raw ingredients. It contains very few inclusions and is almost free of bubbles. WebSep 4, 2024 · Put one of Reflectance Standards ( BK7: for the reflectance of 0-12%; Si: for the reflectance of 12-60%; Al: for the reflectance of 60-100%) onto the sample stage with the two bottom bumps fitting into the hole on the sample stage, then, click Take Reflectance Standard button. Let it finish, then, take the standard off the stage. curling wand 09-10
