Preisreferenzen & Detailtabelle für optisches Glas

Welches optische Glas wählen Sie für Ihre optischen Komponenten? Das hängt nicht nur von den optischen Eigenschaften des Glases ab, sondern auch von zwei anderen wichtigen Faktoren: den Preis und die Verfügbarkeit des optischen Glases.

Nachfolgend finden Sie eine umfassende Tabelle mit den meisten optischen Gläsern. Die Tabelle basiert auf CDGM-Referenzen und enthält auch Schott-, Hoya– und Ohara-Glas Äquivalente.

Preisreferenzen für optisches Glas

In der folgenden Grafik ist die Preisreferenzbasis das gebräuchlichste optische Glas H-K9L / N-BK7, welches einen Referenzwert von 10 hat. Alle anderen Glasreferenzpreise zeigen, wie viel teurer (oder günstiger) sie im Vergleich zu H-K9L sind. So hat zum Beispiel H-FK61 einen relativen Preis von 126, was bedeutet, dass es 12,6-mal teurer ist als H-K9L.

Verfügbarkeit von optischem Glas

IIm Gegensatz zu Floatglas wird optisches Glas in Chargen hergestellt. Diese Chargen werden mehrere Monate im Voraus geplant, was bedeutet, dass bei großer Nachfrage nach einer Referenz die Verfügbarkeit zwischen zwei Chargen beeinträchtigt werden kann. Die Verfügbarkeit, wie sie in der Tabelle erscheint, entspricht der Häufigkeit, mit der eine Referenz hergestellt wird, sowie der Frage, ob es einen Sicherheitsbestand gibt oder nicht.

Was bedeuten die Buchstaben in den Glastypen?

Buchstaben in den Glastypen entsprechen spezifischen Informationen über das Glas. Zum Beispiel kennzeichnet CDGM umweltfreundliches Glas (kein Blei, kein Cadmium, kein Arsen) mit dem Präfix „H“ (H-K9L). Dies entspricht dem Präfix „N“ bei Schott.

Mit dem Präfix D kennzeichnet CDGM, dass ein Glas, aufgrund eines niedrigen Schmelzpunktes, leicht formbar ist.

Wie man den Glascode und Glasindex liest

Glascodes werden entsprechend dem internationalen Sprachgebrauch festgelegt, bestehen aus 6 Ziffern und können in zwei 3-stellige Zahlen unterteilt werden: Die drei ersten Ziffern sind der gerundete Wert nach dem Komma des Glasbrechungsindex (nd) und die drei letzten Ziffern sind die Abbe-Zahl (Vd), gerundet auf den Dezimalwert.

Zum Beispiel ist H-BaK2-Code 540597 von nd : 1.53996 (gerundet auf 540) und Vd : 59.72.

Was ist nd & Vd ?

Der nd-Wert steht für den Brechungsindex eines Glases bei 587,56 nm Wellenlänge. Während Vd der Wert der Abbe-Zahl von Glas ebenfalls bei 587,56nm ist. Die Abbe-Zahl wiederum gibt die Dispersion eines Materials an, also wie unterschiedlich verschiedene Wellenlängen gebrochen werden. Lieferanten von optischem Glasmaterial bieten unterschiedliche Toleranzgrenzen für nd und Vd, wobei die engste Klasse 1 (+/-30×10-5 für nd & +/-0,5% für Vd) ist.
