WPZ2412-355-M25.4
Air-spaced zero-order waveplates consist of two quartz plates installed in a mount with an air gap and orthogonal optical axes. The thickness difference between the two quartz plates produces zero-order retardance. Zero-order waveplates are insensitive to temperature and wavelength.
