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 turnaround is needed. We can also accommodate requests for custom shapes sizes (up to 4 inches) and retardance values. Please contact a Meadowlark Optics Solutions Engineer for assistance with your custom requirements.
