A rubidium optical atomic clock uses a modulated 778 nanometer (nm) probe beam and its reflection to excite rubidium 87 atoms, some of which emit 758.8 nm fluorescence as they decay back to the ground state. A spectral filter rejects scatter of the 778 nm probe beams while transmitting the 775.8 nm fluorescence so that the latter can be detected with a high signal-to-noise ratio.

Lighting applications which are particularly difficult to light because of “non-standard” target areas (or otherwise) would benefit from advancements in lighting design. That being said, conventional wisdom in lighting design has practical limitations—conventional means of visors at/on lighting fixtures (i.e., local visoring) can only become so long to provide beam cutoff before becoming prohibitively heavy or costly, for example. Local visoring can only be pivoted so far before beam shift occurs (e.g., shifting the physical location of maximum candela or photometric center), as another example. Conventional wisdom can only buy so much cutoff and beam control before the overall lighting design is impacted—and so an alternative approach is warranted. One such alternative approach which relies upon a combination of remote visoring and local visoring is discussed; additional approaches are also discussed.
