Abstract: A tunable spectral filter includes a first tunable dispersive element, a first optical element, a spatial filtering element located at the focal plane, a second optical element, and a second dispersive element. The first tunable dispersive element introduces spectral dispersion to an illumination beam with an adjustable dispersion. The first optical element focuses the illumination beam at a focal plane in which a distribution of a spectrum of the spectrally-dispersed illumination beam at the focal plane is controllable by adjusting the dispersion of the first tunable dispersive element. The spatial filtering element filters the spectrum of the illumination beam based on the distribution of the spectrum of the illumination beam at the focal plane. The second optical element collects the spectrally-dispersed illumination beam transmitted from the spatial filtering element. The second tunable dispersive element removes the dispersion introduced by the first tunable dispersive element from the illumination beam.

Abstract: A visor assembly may clip onto a mobile electronic device, and may broadly include: an attachment member securable to the device; at least one hinge secured to the attachment member; and a plurality of cascading shroud members, each pivotally coupled to the attachment member using the hinge. Adjacent shroud members are selectively interconnected. Rotational movement of a first shroud member from a retracted position to a first angular displacement, correspondingly drives a second shroud member to rotate in unison. Continued rotation of the first shroud member successively drives remaining shroud members to co-rotate, until it has been rotated to a second angular displacement, and the plurality of shroud members are each then deployed into a respective fully extended position. A friction fit at the interconnection between adjacent shroud members is sufficient to releasably inhibit movement resulting from only a weight of the shroud members and the orientation of the device.
