The LBTEK Achromatic Six-Segmented Waveplate utilizes N-BK7 glass substrate and Liquid Crystal Polymer (LCP) material, consisting of three layers of liquid crystal true zero-order six-segmented waveplates designed and combined at specific angles. In each single-layer LCP film, the fast-axis orientation of liquid crystal molecules is uniform within each segment. The three LCP films are stacked according to the designed angles, with corresponding segments aligned to form the overall fast-axis orientation of the achromatic six-segmented waveplate. By controlling the thickness of each LCP film layer and the relative fast-axis angles of the corresponding segments, the total retardation of each segment is precisely managed. The LBTEK Achromatic Six-Segmented Waveplate is commonly used to achieve different polarization state transformations for incident light in various segments. It features near true zero-order characteristics, supports large incident angles, and exhibits low sensitivity to wavelength and temperature variations. Compared with true zero-order six-segmented waveplates, it is not limited to specific operating wavelengths and can achieve different polarization modifications for incident beams in different segments across a certain wavelength range. The standard achromatic six-segmented waveplate is designed for wavelengths of 400-700 nm with a retardation of λ/2. It is mounted in a standard SM1 lens tube, with the product model and 0° fast-axis segment marking lines engraved on the tube surface for easy identification and use by customers.
