Edmund Optics Inc. 1/2 Wave Precision Zero Order Retarder 632.8nm NT49-211

Description
¼λ and ½λ Retardance Excellent Angular Field of View Birefringent Polymer Stack Precision Zero Order Waveplates (Retarders) feature carefully aligned birefringent polymer sheets laminated between two precision BK7 windows, and are available in standard ¼λ and ½λ options for common visible and NIR wavelengths. These polymer waveplates (retarders) offer excellent angular field of view because they are true zero-order retarders. Also, they will experience less than 1% retardance change over a ±10° angle of incidence. Each Precision Zero Order Waveplates (Retarders) is mounted in a metal ring with the fast axis clearly marked.
