Abstract
In a method of producing a self-focusing reflection grating structure for the series manufacture of microspectrometers including flexible foil strips provided with a grating structure and supported in a microspectrometer housing, a foil is first mounted onto a support member of an ultraprecision turning lathe on which circumferential parallel grooves are cut into the foil by microforming diamonds providing a saw-tooth pattern of annular teeth with predetermined tooth spacing, the foil is then cut into a plurality of foil strips and the strips are bent into a curved shape providing a focusing reflection grating structure.
