Abstract
Description
Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruchs 1.The invention relates to a method according to the preamble of Claim 1.
Der wachsende Lichtwellenleiter (LWL)-Markt und der zukünftige industrielle Bedarf an LWL-Systemen fordern hochpräzise und kostengünstige Koppelkomponenten mit hohem Wirkungsgrad. Diese Komponenten der optischen Nachrichtentechnik benötigen optische Bauteile (Linsen), um Aperturen, Fleckgrößen und Wellenfronten von Sendern, Empfängern und Lichtwellenleitern anzupassen, da mit ein guter Koppelwirkungsgrad erhalten wird. Die derzeit auf dem Markt befindlichen Koppelkomponenten sind, wenn man einen hohen Koppelwirkungsgrad fordert, kompliziert aufgebaut (Mehr fachlinsen) und daher in ihrer Herstellung aufwendig und teuer.The growing fiber optic (LWL) market and the future Industrial requirements for fiber optic systems demand high-precision and inexpensive coupling components with high efficiency. These Components of optical communication technology need optical Components (lenses) for apertures, spot sizes and wavefronts of transmitters, receivers and optical fibers, because with a good coupling efficiency is obtained. The currently on coupling components on the market are, if you have one high coupling efficiency, complicated structure (more specialist lenses) and therefore complex and expensive to manufacture.
Mit Hilfe der Glaspreßtechnik bekommt man hochpräzise und preis werte Glaslinsen. Die eingeprägten brechenden Flächen können asphärisch sein und vermeiden dann weitgehend die durch sphäri sche Flächen bedingten Abbildungsfehler. Bei der Glaspreßtech nik kommt dem Formenmaterial eine besondere Bedeutung zu. Das Formenmaterial mußWith the help of glass pressing technology you get high-precision and price value glass lenses. The embossed refractive surfaces can be aspherical and then largely avoid the spherical ones aberrations caused by the surface. At Glaspreßtech The molding material is of particular importance. The Mold material must
- 1. sich zu einer optisch glatten Oberfläche verarbeiten lassen,1. can be processed into an optically smooth surface,
- 2. hochtemperaturfest bis 1100°C sein und keine physikalische und chemische Wechselwirkung (Ausgasen, Kleben) mit dem Glas eingehen.2. Be high temperature resistant up to 1100 ° C and not physical and chemical interaction (outgassing, gluing) with the glass come in.
Da die Glaspreßtechnik für optische Anwendungen sich noch weit gehend im Entwicklungsstadium befindet, sind nur wenige Verfah ren beschrieben. Die bisher bekannten Verfahren verwenden als Formenmaterial Graphit oder Siliziumcarbid (europäische Patent anmeldung 01 46 315), in die die Linsenform geschliffen wird.Since the glass pressing technology for optical applications is still far are in the development stage, there are only a few processes ren described. The previously known methods use as Mold material graphite or silicon carbide (European patent application 01 46 315) into which the lens shape is ground.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Veredelung von Formenmaterialien für die Glaspreßtechnik zu schaffen, damit diese die oben geforderten Eigenschaften er füllen.The invention has for its object a method for Refinement of mold materials for glass pressing technology too create so that he the properties required above to fill.
Diese Aufgabe wird gemäß dem Kennzeichen des Anspruchs 1 ge löst. Vorteilhafte Ausführungsformen und Weiterbildungen der Erfindung sind in den Unteransprüchen enthalten.This object is ge according to the characterizing part of claim 1 solves. Advantageous embodiments and developments of Invention are contained in the subclaims.
Im Gegensatz zu den bisherigen Verfahren verwendet das erfin dungsgemäße Verfahren kostengünstige, hochtemperaturfeste und gut bearbeitbare Materialien (Metalle und Nichtmetalle) und überzieht diese mit einer Folge von aufgestäubten, metallischen Schichten, die nach erfolgter Diffusion die geforderten Eigen schaften erfüllen. Vorzugsweise können als Grundmaterial die Metalle NiCrSi und Ni und als Nichtmetall Al2O3-Keramik ge wählt werden.In contrast to the previous methods, the method according to the invention uses inexpensive, high-temperature-resistant and easily machinable materials (metals and non-metals) and coats them with a series of dusted, metallic layers which, after diffusion, have the required properties. The metals NiCrSi and Ni and the non-metal Al 2 O 3 ceramic can preferably be selected as the base material.
Ein weiterer Vorteil besteht darin, daß die aufgestäubten Schichten erneuert werden können, ohne das Grundmaterial und damit die Form wieder mechanisch bearbeiten zu müssen.Another advantage is that the dusted Layers can be renewed without the base material and so that the shape has to be machined again.
In diese Grundmaterialien (Metalle und Nichtmetalle) wird mit einem spanabhebenden Verfahren die gewünschte Form, zum Bei spiel Linsenform, geschnitten. Durch einen ersten Aufstäubpro zeß werden diese Materialien mit einer geeigneten Haftschicht überzogen, zum Beipsiel Ti, Ni, NiCr für die Metalle und TiPd für die Al2O3-Keramik. In mehreren Schichten werden dann ab wechselnd Gold bzw. Platin aufgestäubt. Die Schichtdickenver hältnisse sind dem jeweiligen Glastyp angepaßt. Sehr gute Er gebnisse werden mit 90-95 Vol-Prozent Platin und 5-10 Vol- Prozent Goldanteil erzielt. Bis zu einem Temperaturbereich von 1000°C ist eine Gesamtschichtdicke von 1 bis 2 µm ausreichend. Die auf diese Weise hergestellten Preßformen zeigen keine Wech selwirkung mit dem Glas (Blasenbildung und Kleben).The desired shape, for example lens shape, is cut into these basic materials (metals and non-metals) using a cutting process. Through a first dusting process, these materials are coated with a suitable adhesive layer, for example Ti, Ni, NiCr for the metals and TiPd for the Al 2 O 3 ceramic. Gold and platinum are then alternately dusted in several layers. The layer thickness ratios are adapted to the respective glass type. Very good results are achieved with 90-95 vol percent platinum and 5-10 vol percent gold. Up to a temperature range of 1000 ° C, a total layer thickness of 1 to 2 µm is sufficient. The molds produced in this way show no interaction with the glass (blistering and sticking).
