  • Method for producing a transmissive optics
    Patent number: 11786994
    Abstract: In a method for the manufacture of a transmissive optical system from a blank, material ablation is achieved on the blank with an ablative laser, and the pulse duration of the ablative laser is less than 1 ns, and preferably lies between 3 fs and 100 fs, or between 100 fs and 10 ps.
    Type: Grant
    Filed: October 12, 2017
    Date of Patent: October 17, 2023
    Assignee: AIXLENS GMBH
    Inventors: Axel Von Wallfeld, Reinhart Poprawe, Christian Fornaroli, Edgar Willenborg, Christian Weingarten, Uwe Clasen

  • Method for smoothing and polishing surfaces by treating them with energetic radiation
    Patent number: 7592563
    Abstract: The present invention relates to a method for smoothing and polishing surfaces by treating them with energetic radiation, in particular laser radiation, in which the to-be-smoothed surface is remelted in a first treatment step using said energetic radiation and employing first treatment parameters at least once down to a first remelting depth of approx. 5 to 100 ?m, which is greater than a structural depth of the to-be-smoothed structures of said to-be-smoothed surface, wherein continuous radiation or pulsed radiation with a pulse duration of ?100 ?s is employed. The method makes it possible to automatically polish any three-dimensional surface fast and cost effective.

  • Method for smoothing and polishing surfaces by treating them with energetic radiation
    Publication number: 20060081573
    Abstract: The present invention relates to a method for smoothing and polishing surfaces by treating them with energetic radiation, in particular laser radiation, in which the to-be-smoothed surface (1) is remelted in a first treatment step using said energetic radiation (3) and employing first treatment parameters at least once down to a first remelting depth (10) of approx. 5 to 100 ?m, which is greater than a structural depth of the to-be-smoothed structures of said to-be-smoothed surface (1), wherein continuous radiation or pulsed radiation (3) with a pulse duration of ?100 ?s is employed. The method makes it possible to automatically polisch any three-dimensional surface fast and cost effective.
