摘要:
A system for re-distributing light emitted from a light source using an optical element is described. The optical element is manufactured using a bulk matrix material, and diffusing particles and/or scattering particles are embedded within the bulk material. The optical element is coupled to the light source to capture emitted light and redistribute the light in a desired angular distribution pattern depending on the ratio of total weight of diffusing particles to total weight of scattering particles.

An improved night vision goggle (NVG) compatible backlight for a liquid crystal display (LCD) and active matrix liquid crystal display (AMLCD) and other types of backlit displays is disclosed. The backlight includes a ridged prismatic TIR with an embedded diffuser layer doped with an infrared (IR) absorbing dye (57), a ridged prismatic TIR without diffuser layer (59) an infrared rejecting filter layer (63), and either a holographic diffuser layer or a lenticular lens array layer (65), or a fresnel wedge layer (67).

摘要:
A method and apparatus for ultrasonic assisted deposition of a release agent onto a workpiece is disclosed. The release agent can be any fluorinated or non-fluorinated phosphorous-containing organic acid. The workpiece can be any workpiece desired to be coated with the release agent, such as a surface needing an anti-stick coating required in a plastic casting or injection mold. Metal oxide workpiece surfaces strongly bond to fluorinated phosphorus-containing organic acids. In particular, the present invention can deposit anti-stick coatings onto smooth or porous surfaces, such as anodized aluminum and its alloys, using ultrasonic assisted deposition.
摘要:
A method and a system for fabricating articles made from thermoset resins using an ionic mold release agent. The invention uses a mold having a metal oxide surface with enhanced mold release characteristics. The release agent is applied internally in the resin composition or externally on the metal oxide surface. The method includes providing a mold, forming a metal oxide surface on the mold, providing an ionic release agent, providing the acid or base conjugate of the release agent at the metal oxide surface, providing a thermoset resin in the mold, and curing the resin in the mold. A method of using float glass having a SnO2 enriched surface, wherein the method includes the steps of providing an ionic release agent externally to the tin oxide surface, is also disclosed.
摘要:
A solid-state dye laser and technique for achieving multiple output wavelength laser emission from a single solid-state dye laser media containing multiple dyes without tuning elements. When the multiple dyes within the single solid-state host are excited with a single wavelength pump source to lase, there results simultaneous multi-spectral output proportional to dye concentration ratios.
