Claims (8)

1. Fremgangsmåde (21) til fremstilling af en optisk præform omfattende trinnene at: - fremstille (22, 27) et substratrør (12), som har pådampede glaslag på indersidens overflade; - forøge (23) en ydre diameter på substratrøret (12) ved at påføre en bevægelig varmekilde for at opvarme substratrøret (12) til over dets blødgøringstemperatur og ved at fremstille et internt tryk i substratrøret (12) som er højere end omgivelsestrykket, efterfulgt af trinnet at: - kollapse (24) substratrøret (12), med en forøget ydre diameter, ved at påføre den bevægelige varmekilde for at opvarme substratrøret (12) til over dets blødgøringstemperatur, således at en optisk præform bliver fremstillet.
2. Fremgangsmåde (21) til fremstilling af en optisk præform ifølge krav 1, som yderligere omfatter trinnene at: - måle en forskel i trykket mellem det interne tryk i substratrøret (12) og omgivelsestrykket, og - styre det interne tryk på basis af målingen og en prædefineret trykværdi.
3. Fremgangsmåde (21) til fremstilling af en optisk præform ifølge krav 2, kendetegnet ved, at den prædefinerede trykværdi er mellem 10 og 100 Pascal, fortrinsvis mellem 30 og 65 Pascal, mere fortrinsvis mellem 40 og 50 Pascal, og endnu mere fortrinsvis omkring 45 Pascal.
4. Fremgangsmåde (21) til fremstilling af en optisk præform ifølge et hvilket som helst af de tidligere krav, kendetegnet ved, at den temperatur der påføres substratrøret (12) under det forøgende trin er mindst 1900 °C.
5. Fremgangsmåde (21) til fremstilling af en optisk præform ifølge krav 4, kendetegnet ved, at den temperatur der påføres substratrøret (12) under det kollapsende trin (24) er mindst 2100 °C.
6. Fremgangsmåde (21) til fremstilling af en optisk præform ifølge et hvilket som helst af de tidligere krav, kendetegnet ved, at det forøgende trin (23) for den ydre diameter på substratrøret (12) udføres flere særskilte gange.
7. Fremgangsmåde (21) til fremstilling af en optisk præform ifølge et hvilket som helst af de tidligere krav, hvor trinnet at fremstille (22, 27) et substratrør (12) som har pådampede glaslag på indersidens overflade omfatter trinnene at; - fremstille (25) et substratrør (12); - pådampe (26) glaslag på indersiden af substratrøret: - levere glasdannende forløbere til det hule substratrør (12) via en tilførselside deraf, hvor det hule substratrør (12) yderligere omfatter en udgangsside, og - påføre en bevægelig reaktionszone indeni substratrøret (12) langs en længde på det hule substratrør (12) med det formål at skabe omstændigheder for pådampning til den glasdannende forløber i det hule substratrør (12), således at der fremstilles et substratrør (12) med pådampede glaslag på indersidens overflade.
8. Fremgangsmåde ifølge krav 7, hvor trinnet at pådampe (26) glaslag på indersiden af substratrøret (12) benytter en proces med plasmakemisk pådampning, PCVD.
