Abstract
A waveguide for conveying light with an input end and an output end to supply for an electromagnetic spectrometer includes: an input end having a convex envelope of a cross-section of the waveguide at the input end, which envelope defines a circular shape or a shape of a regular polygon with n1 corners, wherein n1 is a natural number bigger than 3; an output end having a cross-section that defines a slit shape; and a plurality of filaments, wherein an arrangement of the plurality of filaments defines the cross-sections at the input and output ends, wherein each filament includes a core and a reflective coating covering a lateral area of the core, wherein the core includes an optically transparent material.
Claims20
A waveguide of an electromagnetic spectrometer, the waveguide comprising:
- a plurality of filaments, each configured to convey light from an input end to an output end thereof, wherein a first convex envelope of a cross-section of the waveguide at the input end defines a first shape, and wherein a second convex envelope of a cross-section of the waveguide at the output end defines a slit shape,
- wherein each filament of the plurality of filaments comprises a core and a reflective coating covering a lateral area of the core, wherein the core comprises an optically transparent material, and wherein a cross-section of each filament defines a regular polygon with n2 corners, wherein n2 is 3, 4 or 6.
