Fluorescent lamp having externally coated UV ray absorbing film

Pseudo-Brewster and second-Brewster angles of an absorbing substrate coated by a transparent thin film.

Fiat Lux: A Fluorescent Lamp Tkansceiver

The prevalence of electric discharge illumination has led us to consider ways to use discharge lamps for communication. This paper describes an optical transceiver system which transmits by modulating the lamp arc. The prototype power electronic lamp ballast uses a pulse frequency modulation scheme which ensures no perceptible flicker.

Fluorescent Lamp Modelling for Voltage Fluctuations

Ray tracing in absorbing media

In ray tracing, it is standard practice to consider solely the real part of any medium’s refractive index for determining the changes in a ray’s direction at the interface between two media. Any absorption is accounted for by reducing the intensity or weight of the ray in accordance with its propagation distance. This practice is adequate at optical wavelengths where absorption is generally ver...

Fabrication of flexible UV nanoimprint mold with fluorinated polymer-coated PET film

UV curing nanoimprint lithography is one of the most promising techniques for the fabrication of micro- to nano-sized patterns on various substrates with high throughput and a low production cost. The UV nanoimprint process requires a transparent template with micro- to nano-sized surface protrusions, having a low surface energy and good flexibility. Therefore, the development of low-cost, tran...
