1. Laite spektrianalyysin suorittamiseksi/ joka laite käsittää elimet (10) säteilyn johtamiseksi sisään 5 laitteeseen, elimet aikaansaadun spektrin rekisteröimiseksi ja parillisen määrän porrashiloja (1-6, 12-15), jotka ovat pareittain identtisiä sisään tulevan säteilyn hajottamiseksi niin, että aallonpituusdispersio yhdeltä porrashilalta tapahtuvan diffraktion yhteydessä aikaansaa lisäyksen aal-10 lonpituusdispersiossa seuraavalta porrashilalta tai seuraa-vilta porrashiloilta tapahtuvan diffraktion yhteydessä, jolloin kunkin parin hiloilla on sellainen suuntaus, että kunkin parin ensimmäisen hilan (1, 2) tulokulma OO on likimain yhtä suuri kuin toisen hilan (2, 13) diffraktio-15 kulma φ), ja että ensimmäisen hilan (1, 2) diffraktiokulma </$) on likimain yhtä suuri kuin toisen hilan (2, 13) tulo-kulma (0<) , tunnettu siitä, että hilat (1-6, 12-15) on sovitettu ensimmäiseen ilmatiiviiseen säiliöön (18), joka on varustettu elimillä ensimmäisen säiliön kaasunpai-20 neen säätämiseksi spektrin pyyhkäisemiseksi.
2. Patenttivaatimuksen 1 mukainen laite, tunnettu siitä, että se käsittää lähtöraon (17), josta säteily johdetaan toiseen alloon pituutta dispergoivaan optiseen elimeen (25), jonka avulla säteilyyn sisältyvät 25 allonpituudet, jotka vastaavat hilojen spektrijärjestyksiä, erotetaan toisistaan ja fokusoidaan polttotasossa (26), jolloin mainittu toinen elin on suunnattu siten, että allonpituusdispersio mainitusta toisesta elimestä tapahtuu likimain samassa tasossa kuin aallonpituusdispersio hiloissa. 30
3. Patenttivaatimuksen 2 mukainen laite, tun nettu siitä, että mainittu toinen elin (25) on suljettu toiseen ilmatiiviiseen säiliöön (21), joka on yhteydessä ensimmäisen säiliön (18) kanssa, niin että kummassakin säiliössä vallitsee sama paine. Il
