Two systems proposed to increase wavelength resolution. Two paraboloidal reflectors and grating separate light into component colors. First paraboloid forms input light into nearly planar waves. Reflected from planar grating at various angles depending on wavelength. Second paraboloid focuses separate wavelengths to separate lines.
