WebMiniature anastigmatic spectrometer design with a concave toroidal mirror An advanced optical design for a low-cost and astigmatism-corrected spectrometer with a high resolution is presented. The theory and method of astigmatism correction are determined with the use of a concave toroidal mirror. WebFor comparison, an Al-mirror based optical system using three mirrors achieves only about 78% efficiency in light transmission at 532 nm excitation wavelength. If the number of mirrors used increases, the light transmission efficiency drops further.
