Based on the holographic concave grating theory and ZEMAX software, an aberration-corrected flat-field holographic concave grating on aspherical surface for a flat-field spectrograph is designed.
基于全息凹面光栅理论和ZEMAX软件,设计了一种用于平场光谱仪的消象差平场非球面全息凹面光栅。
The spectral resolution of the spectrometer will be seriously deteriorated by radius error which is inevitable in the flat-field holographic concave grating fabrication.
