The Compound Polarizer

Wire Grid Infrared Polarizer

A useful polarizer for the 6-y to 2 0-u region has been designed, fabricated, and tested. A microscopic wire grid was formed by ruling Irtran 2 (ZnS) or Irtran 4 (ZnSe) and evaporating aluminum preferentially on the groove tips. The average transmittance for the crossed polarizers in the 8-JA to 2 -u region was less than 1%. The degree of polarization was insensitive to a wide range of incidenc...

Carbon nanotube terahertz polarizer.

We describe a film of highly aligned single-walled carbon nanotubes that acts as an excellent terahertz linear polarizer. There is virtually no attenuation (strong absorption) when the terahertz polarization is perpendicular (parallel) to the nanotube axis. From the data, the reduced linear dichrosim was calculated to be 3, corresponding to a nematic order parameter of 1, which demonstrates nea...

Multilayer Polarizer Panels

Fluorescent lamp luminaires with multilayer polarizer panels produce partially polarized light*, which can increase the contrast of a visual task under some viewing conditions. In principle, a decrease in illuminance can accompany an increase in task contrast without affecting visual performance. Because a reduction in illuminance implies a reduction in the electric power used for lighting, mul...

The polarization properties of a tilted polarizer.

Polarizers are key components in optical science and technology. Thus, understanding the action of a polarizer beyond oversimplifying approximations is crucial. In this work, we study the interaction of a polarizing interface with an obliquely incident wave experimentally. To this end, a set of Mueller matrices is acquired employing a novel procedure robust against experimental imperfections. W...
