Polarizers

Meadowlark Polarizers Offer:

  • Wide Range of Options –  Circular, Linear, and Beam splitting categories.
  • Broad Wavelength Capabilities – Our standard polarizers are designed for use in the 220-nm to 6-micron range (with custom options up to 15 microns.)
  • High Quality and Precision – Meadowlark Optics is proud to provide our customers with industry-leading specifications including excellent surface quality, high extinction ratio, low transmitted wavefront distortion, and more.
  • Custom Solutions – Prism clusters, attached retarders, odd shapes and sizes – while we are delighted to provide you one of our standard components or systems, we are just as happy to customize a solution that more exactly fits your needs.

What Polarizers Do

A polarizer is a type of optical filter that only allows light waves of a certain type to go through, while blocking other types. It can turn a mixed or undefined light beam into a clear, polarized light beam. There are two main kinds of polarizers: linear and circular. They’re used in many areas such as photography, LCD technology, and various optical tools. Not only for visible light, polarizers can also work with other electromagnetic waves like radio waves, microwaves, and X-rays. Linear polarizers can be absorptive, which means they absorb unwanted light types, reflective, which means they reflect unwanted light types, or beam-splitting, which means they break the light beam into two opposite types. Circular polarizers can make circularly polarized light or selectively let through or block light that’s spinning clockwise or counter-clockwise. Meadowlark offers both linear and circular polarizers.
