Key Features

  • Very thin profile
  • Thermally stable
  • High volume scalable
  • AR coatings available
  • Custom retardance available

Meadowlark Optics is pleased to present our Bare Polymer Film Retarder. Our proprietary polymer film provides high retardance accuracy in a cost-effective product which can be provided in almost any configuration and quantity. The temperature dependence of the nominal retardance is approximately 0.01 %/°C, which provides a very stable and versatile polarization solution.​

Manufactured in-house for wavelengths between 400 and 1800 nm, this retarder is ideal for applications requiring a high-precision, thin, and cost-effective solution. We are also able to tune the retardance to your Angle of Incidence to optimize performance. AR coatings are available on a special order basis. Standard shapes and retardance values are available when quick turn-around is needed. We can also accommodate requests for custom shapes sizes (up to 4 inches) and retardance values.​
