How does mass photometry work
Web28.5.1 Photometers. A typical photometer head for measurements of illuminance (the amount of visible light per square meter falling on a plane) is shown in Figure 28.13. Incident light falls on the opal glass cylinder A, and some reaches the detector surface C after passing through the filter layer B.
