Abstract: The disclosure provides an improved fiber optic cable assembly that can protect spectrometers against one or more of the external noise and discharge sources. The improved fiber optic cable assembly provides electrical isolation and/or insulation (EII) protection for optical instruments, such as a spectrometer, in which the fiber optic cable assembly is terminated. The EII protection can include one or more of a non-conductive sheathing at least partially covering the termination and the sheathing, a dielectric break providing electrical isolation between the termination and the sheathing, an isolation boot, and a grounding tether. In one example a fiber optical cable assembly includes: (1) a termination, (2) sheathing, and (3) a dielectric break providing electrical isolation between the termination and the sheathing. A fiber optically coupled system having an improved fiber optic cable assembly is also disclosed.

Abstract: A luminaire that has multiple removable handles thereon, and can operate in multiple different modes, including a mode where a manual follow spot can occur. To operate in the manual follow spot mode, the luminaire is placed into a free moving mode in which it can be moved, and then the luminaire is moved using the removable handles to manually place the luminaire in a desired location. Then, the luminaire is commanded to remain in that desired location by turning on breaks or the like. In the manual movement mode, movement of the luminaire is manually controlled and not remotely controlled and all of at least color, gobo, beam size and other parameters are remotely controlled.

Abstract: A gobo holder with two gobos that are rotatable one relative to the other. The gobos are located with their patterned surfaces facing one another and very close to one another so that both can be in focus at the same time.
