摘要： Layers of material such as glass layers for displays may be cut using scribing and breaking techniques. Scribing-and-breaking equipment may include a scribe tip that forms a loop-shaped scribe line in the surface of a layer of material. The loop-shaped scribe line may have a rectangular shape with four straight sides and four rounded corners. A breaking structure such as a rectangular ring-shaped metal break frame with rounded corners may be configured to match the shape of the scribe line. During breaking operations, the layer of material may be supported on a support structure. The support structure may have a flexible material such as an elastomer and a lower-friction coating layer such as a polytetrafluoroethylene coating. The break frame may be aligned with the scribe line and may be used to press down on the layer of material, thereby breaking the layer of material along the scribe line.

摘要： A hyper-spectral imaging filter has serial stages along an optical signal path with angularly distributed birefringent retarders and polarizers forming interference filters. The retarders can include tunable birefringent elements such as liquid crystals controlled in unison, fixed retarders and/or combined tunable and fixed birefringences. Distinctly different periodic transmission spectra are provided by different filter stages, each having multiple retarders, in particular with some stages having broad bandpass peaks at wide spectral spacing and other stages have very narrow closely spaced peaks. The respective spectra include at least one tunably selectable band at which the transmission spectra of the filter stages coincide, whereby the salutary narrow bandpass and wide spectral spacing ranges of different stages apply together, resulting in a high finesse wavelength filter suitable for spectral imaging.
