Edmund Optics Inc. Polymer Achromatic Retarder 1/4 wave 920-1240nm NT49-235

Description
Broad Spectral Range 1/100λ Surface Accuracy ¼λ and ½λ Retardance Precision Achromatic Waveplates (Retarders) consist of a polymer stack layered between two precision BK7 windows, and are available in standard ¼λ and ½λ options for common visible and NIR wavelengths. These waveplates (retarders) will experience less than 1% retardance change over a ±10° angle of incidence. Each Precision Achromatic Waveplates (Retarders) is mounted in a metal ring with the fast axis clearly marked.
