Abstract

For å undersøke fremkallingen til et fotoreslst sjikt (2) på en optisk masterdlsk (1) ved et fremkallerfluid (14) er et transparent legeme (4, 35, 50) bragt l kontakt med fremkallerfluldet (14). En lysstråle (6) er ført Inn på den optiske masterdlsken (1) fra en kilde (5) og en dlffraktert stråle (8) passerer gjennom fremkallerfluldet (14) og det transparente legemet (4, 35, 50) til en detektor (9). På denne måten er den optiske banen til den dlffrakterte strålen (8) stabil. Den diffrakterte strålen (8) er fortrinnsvis generert fra den Innfallende lysstrålen (6) ved refleksjon og fortrinnsvis er den en første-ordens diffraktert stråle. Det foretrekkes også at den innfallende lysstrålen (6) moduleres. Fremkallingen av fotoresist- sjiktet blir så overvåket ved å overvåke endringer i den dlffrakterte lysstrålen (8) detektert av detektoren (9).
