DESCRIPTION
Polymer Film Retarders
Meadowlark Optics is pleased to present our Bare Polymer Retarder film. 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 1800nm, this retarder is ideal for applications requiring a high precision, thin and cost effective solution.

Manufactured in-house for wavelengths between 400 and 1800nm, 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.
Please contact a Meadowlark Optics Sales Engineer for assistance with your custom requirements.
