(FR) PROCÉDÉ DE FABRICATION D'UN SYSTÈME OPTIQUE À TRANSMISSION OU RÉFLEXION ET LENTILLE
(DE) VERFAHREN ZUR HERSTELLUNG EINER TRANSMITIVEN ODER REFLEKTIVEN OPTIK UND LINSE
Abstract:
(EN) In a method for producing a transmissive or reflective optical element from a blank, material is removed from the blank by means of a material removal laser and the pulse duration of the material removal laser is less than 1 ns and is preferably between 3 fs and 100 fs or between 100 fs and 10 ps.
(FR) L'invention concerne un procédé de fabrication d'un système optique à transmission ou réflexion à partir d'une ébauche, consistant à soumettre l'ébauche à un enlèvement de matière au moyen d'un laser d'enlèvement, la durée d'impulsion du laser d'enlèvement étant inférieure à 1 ns et de préférence comprise entre 3 fs et 100 fs ou entre 100 fs et 10 ps.
(DE) Bei einem Verfahren zur Herstellung einer transmitiven oder reflektiven Optik aus einem Rohling, wird an dem Rohling mit einem Abtragslaser ein Materialabtrag erzielt und die Pulsdauer des Abtragslasers ist kleiner 1 ns und liegt bevorzugt zwischen 3 fs und 100 fs oder zwischen 100 fs und 10 ps.
