A device may generate a multi-layer stack of sheets that may be adhered into a slab-shaped preform for thermal drawing. The sheets may include sublayers. Stacking the sub-layered sheets results in accumulation of layers in the final fabricated preform. The stacking process may use mechanical translation and conveyance to support placement of the sheets and fabrication of the stack.

Structured preforms for thermal drawing

A method of making an optical filter film with varying optical properties includes the step of drawing a multilayer polymeric preform into an optical filter and varying at least one environmental condition being a member of the group including of heat, pressure, tension, and a drawing speed, the at least one environmental condition being varied over time or over a distance, or both, and causing a variation in layer thickness within the optical filter. The preform may be drawn through a furnace subjecting the preform to a heating power that varies across a width of the furnace or over time or both across the width and over time. The preform may also be drawn through the furnace while the drawing speed varies across a width of the furnace or over time or both across the width and over time.

Ultra-thin, flexible thin-film filters with spatially or temporally varying optical properties and methods of making the same

A hybrid optical filter includes a plurality of film layers laminated to one another. This renders the filter flexible enough to be bendable and to implement a combination of at least two different wavelength-dependent optical filtering properties in a single hybrid optical filter. Two or more of the optical filtering properties may be caused by interference-based blocking of different ranges of wavelengths of light. Additionally or alternatively, at least one of the optical filtering properties may be an absorptive blocking of a first range of wavelengths of light and at least another one of the optical filtering properties is an interference-based blocking of a second range of wavelengths of light. The first range of wavelengths and the second range of wavelengths may overlap to provide for customized ranges of blocked wavelengths.
