摘要:
A method includes scanning a radiation beam with respect to a multiphoton curable photoreactive composition. The radiation beam includes a power sufficient to at least partially cure a volume of the multiphoton curable photoreactive composition. The method further includes modifying a characteristic of the radiation beam as the radiation beam is scanned.
摘要:
Presently described are hardcoat compositions comprising at least one first (meth)acrylate monomer comprising at least three (meth)acrylate groups and C2-C4 alkoxy repeat units wherein the monomer has a molecular weight per (meth)acrylate group ranging from about 220 to 375 g/mole and at least one second (meth)acrylate monomer comprising at least three (meth)acrylate groups. The hardcoat composition further comprises inorganic oxide nanoparticles such as silica that comprises a copolymer izable surface treatment and a non-copolymerizable silane surface treatment. Also described are articles, such as protective films, displays, and touch screens comprising such cured hardcoat compositions.
摘要:
A system comprising a substrate having thereon a multiphoton curable photoreactive composition, a light source that emits a light beam comprising a plurality of wavelengths onto at least one region of the composition on the substrate, and a detector that detects a portion of light reflected from the composition to obtain a location signal with respect to the substrate, wherein the location signal is based at least on a wavelength of the reflected light.
摘要:
A fusion splice including a first optical fiber having a first MFD and a first MFD expansion rate. The splice further includes a second fiber (100) having a second MFD and a second MFD expansion rate, wherein the second MFD is lower than the first MFD. The second fiber comprises a core (110), a cladding (130) radially surrounding the core, and a zone (120) of high-concentration of fluorine between the core and the cladding. The rate of MFD expansion of the first fiber is less than the rate of MFD expansion of the second fiber during the fusion splicing operation.
