General Information
A Linear Polarizer accepts an unpolarized input beam and converts it to a linear- polarized output beam. Linear Polarizers available from ColorLink® take advantage of polymer film dichroic materials, sandwiched between antireflection-coated glass substrates.
Dichroic materials absorb light polarized in one direction and transmit the orthogonal polarization. The most common materials used as dichroic polarizers are stretched polyvinyl alcohol sheets treated with either dye-stuff or iodine solution
ColorLink Polarizers are lightweight, rugged, and thin. These Polarizers are widely viewed as the most useful polarizers available as they are relatively insensitive to incidence angle, produce negligible beam deviation, and can be manufactured in a variety of sizes and shapes using our unique assembly process.
In general, we characterize the performance of a Linear Polarizer by its transmittance and extinction ratio, or polarizing efficiency. It is important to note that a perfect Linear Polarizer transmits only 50% of an unpolarized incident beam.
ColorLink offers Linear Polarizers for use across the visible spectrum, now available in custom sizes and shapes – from prototype to high volume production using our cost effective production assembly process.
