Abstract
A single-wavelength light source is configured to generate an excitation light source. A sample holder that defines an inner cavity is capable of holding a sample and includes a surface transparent to the excitation light source. One or more mounts are attached to at least one of the light source or the sample holder. The mounts are configured to change an incident angle of the excitation light source on the surface. One or more optical components are positioned in a path of a fluorescence emission emitted from the surface and guide the fluorescence emission to a detector. A detector detects an intensity of the fluorescence emission.
