| Abstract: | A superior hologrphic flat reflection grating with 0.448μm spectral line obtained from a single frequency Ar+ laser is fabricated. Its characteristics are: Spatial frequency ≈ 2400 条/mm-1 , wave aberration of first order diffraction < λ / 6 , diffraction efficiency in ultraviolet domain= 45% . This grating has become a necessary component of WSP-1 model flat grating spectrograph for batch process and is used in other spectrograph or monchrometer. |
