摘要:
A polarization optical element causes minimum loss and provides light in the visible and near-infrared regions with practically satisfactory polarization contrast even when the grid period is comparatively long. Metal grids 1 are formed on a substrate 2 with a refractive index n.sub.1 to satisfy conditions 0.2
