Optikkleber von Norland sind transparente, lösungsmittelfreie Kleber für Optiken, die im ultravioletten Licht innerhalb von Minuten aushärten. Die Kleber werden zur präzisen Ausrichtung oder Positionierung eingesetzt, wenn eine robuste und dauerhafte Klebeverbindung benötigt wird. Optikkleber von Norland sind für eine Vielzahl von Materialien geeignet, u. a. für Glas auf Glas, Glas auf Glas/Metall und Kunststoff auf Kunststoff/Glas. Der Optikkleber wird einfach auf die optische Grenzfläche aufgetragen, die Komponenten werden justiert und sind nach dem Aushärten im UV-Licht fixiert. Da der Klebstoff nur unter UV-Licht aushärtet, ist die Positionierung nicht zeitkritisch.
Norland Optical Adhesives are clear, solvent-free, one-part adhesives designed for precision optical bonding applications requiring excellent optical quality and a durable, low-stress bond.
These adhesives cure rapidly when exposed to UV light, gelling in seconds and fully curing in minutes, which allows users to precisely align lenses, prisms, filters, and other components before initiating cure.
They are widely used in photonics and optomechanical assembly for bonding glass-to-glass, glass-to-metal, and glass-to-plastic interfaces where fast, controlled positioning is critical.
Standard UV-curing formulations provide long working time since the adhesive remains liquid until exposed to UV, enabling high-precision alignment and simplified assembly workflows.
Select formulations with an “-H” suffix incorporate a secondary heat cure mechanism, allowing the adhesive to fully polymerize in shadowed areas or through opaque substrates where UV light cannot reach.
These heat-curable adhesives typically use a latent thermal catalyst (e.g., ~125 °C cure) to complete the cure and achieve maximum physical properties after initial UV fixation.
For product usage, apply the adhesive, align components, use UV light for initial set, and apply heat when required to ensure complete cure throughout the bond line, especially in complex geometries.
Important technical considerations include selecting the appropriate refractive index and bonding compatibility, as well as accounting for oxygen inhibition in heat-curing (-H) grades, which may require inert atmosphere curing for exposed surfaces.
