Description
Meadowlark Optics Precision Achromatic Retarders are designed to provide a nearly constant retardance over a broad wavelength region. Standard quarter- and half-wave devices are available for common wavelength regions in the visible and near infrared.
Our Precision Achromatic Retarders consist of carefully aligned birefringent polymer sheets laminated between precision polished, optically flat N-BK7 windows.
Assembly is quite similar to the assembly of our Precision Retarders. Optical transmittance varies slightly from the Precision Retarder because several polymer layers are used in each Achromatic Retarder. We provide retardance accurate to λ/100 for all wavelengths in the operating range.
Achromatic retarders are an excellent choice for applications requiring broad wavelength use.
