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. WebUnlike visible materials (such as N-BK7) that work well throughout the entire visible spectrum, IR materials are often limited to a small band within the IR spectrum, especially when anti-reflection coatings are applied. list of classes in school
