Wave plate and optical device using the same
摘要:
The present invention provides a wave plate capable of obtaining preferable phase conversion characteristic over a wide wavelength range. The wave plate includes an aluminum oxide film having linear grating groove patterns. The period L (μm) and the duty ratio De of the grating groove patterns are set at values within the first range specified by the following four formulas: L≦0.65 L≧2×10−14e31.263De L≦6.0317De2−10.352De+5.0516 (De−0.85)2/0.442+(L−0.41)2/0.392≦1
