Abstract

The invention relates to a manufacturing method for a microminiaturized optical spectrograph slit. Firstly, a slit billet is subjected to oxidization, adhesive coating and photoetching to form a pattern with scallops, the pattern with the scallops undergoes corrosion, adhesive removal, adhesive coating and photosetching to form a slit hole pattern, the silt hole pattern is subjected to ICP etching or wet corrosion to form a slit billet of an impervious groove, and then the slit billet of the impervious groove is subjected to the adhesive removal, the ICP etching or the wet corrosion to obtain the scallops and a slit hole. The slit with small volume and low price is prepared by a micro-machined technology, so a microminiaturized optical spectrograph has the advantages of compact structure, small volume and the reduction of manufacturing cost, and is easier for integration.
