WebStandard optical glasses offer high transmission throughout the entire visible spectrum and beyond in the near-ultraviolet and near-infrared ranges ( Figure 1 ). Figure 1 shows internal transmission of 5mm thick substrates without Fresnel reflections. Transmission data was gathered using Edmund Optics’ spectrophotometers. 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 ...
