The present invention provides improved optical elements, such as light diffusing films, plates, and lenses, which can be used in light-emitting devices, such as light fixtures to c
For high transmittance in the visible wavelength region, researchers encountered some additional challenges in creating superhydrophobicity, such as (a) the roughness level of the surface and (b) keeping the refractive index low. A review of recent literature reports that most of the published works...
The greater impact of the achromatic lens compared to the Fresnel lens system (+7.5%) is due to the important amount of polycarbonate in achromatic lenses. Composite material (polycarbonate with glass fiber used for mirror support) can have a significant contribution. The benefits of recycling ...

An alignment fixture holding the second lens conforms to the curvature of the second lens, and a deformable sheet mounted proximate to the alignment fixture flexes in response to the force so that either of the first or second lenses conforms to a curvature of the other, and so that the ...
Methods are disclosed which utilize polycarbonate to form solid optical lenses. The polycarbonates may be selected from high molecular weight linear or branched species. Viscosity and melt flow are specified for improved mechanical properties. The method provides lenses with greater resistance to cracking...
