Optical Adhesives available from Stock
Our broad range of state-of-the-art adhesives (glues) is used for fast, high-precision bonding of optical components, where the adhesive is index-matched to the used components. While highly specialized, the adhesives are especially designed to meet a very wide range of applications, providing strong bonds to glass, metal, ceramics and plastics.

Packaged in syringes, bottles or bags of various sizes, our optical adhesives available from stock simplify bonding processes that require critical alignment or exact positioning. They guarantee high processing speed combined with high reliability. Curing conditions can differ, using either heat or UV light to reach the optimum adhesion.

Our broad range of one-component UV-curing optical adhesives will set in seconds when exposed to ultraviolet light and can provide excellent light transmission over a wide spectral range. These optical adhesives are designed for bonding, where low strain, optical clarity or low outgassing are required in military, aerospace, fiber optics or commercial optics. Every adhesive is index-matched, with refractive indices available in the range from 1.315 to 1.7. If you need a portfolio of adhesives for various refractive indices, kits containing bottles with the most frequently used adhesives might be your products of choice.

Two component, 100% solids, heat curing epoxy adhesives are also available from stock, designed for high-temperature applications. These adhesives will perform continuously at +200 °C while also tolerating +300 °C to +400 °C for several hours.

Product Portfolio
In addition to the optical adhesives available from stock, we support a range of epoxy- or acrylate-based adhesives for various purposes. Special glues have been developed for the use with optical waveguides, for assembling optical fiber arrays, e.g. to fix optical fibers in v-grooves, as well as high-precision variants or adhesives with either low or high refractive index.

We also carry high refractive index, UV-curable resins for nano imprint lithography, providing highly functional fine patterns with high accuracy. Our series of sealants for optical parts is suitable for applications like sealing the openings and junctions of protective casings with very low moisture permeability.

Definition
Bonding is an essential technological process in many industries, utilizing adhesives to either fix or connect components made of various materials. Optical adhesives usually exist in liquid or paste form and are used to fix or bond together optical components of all kinds (optical fibers, optical parts such as prisms or lenses, displays, glasses, etc.).

Single- and multi-component adhesives are available, whose curing can be done by either ultraviolet light or elevated temperature. Curing by UV light usually happens in a very short time (a few seconds), which facilitates precision alignment or positioning of the optical components to be bonded.

Optically transparent adhesives are light-transmitting and are therefore suitable for use in the optical path. Optical bonding is often used to optimise the optical path at the joint, but for this the transmittance and the refractive index of the adhesive used must be matched to the components to be bonded.

Optically opaque adhesives are used when no light is to be transmitted through the adhesive – for example for bonding a mirror to a suitable holder. This type of adhesive is usually based on two components and does not require UV light for curing.

How to Select the Right Optical Adhesive
Each type of optical adhesive has strengths and limitations, so selecting the most suitable adhesive for the job can be a challenge. The material properties of the adhesive required for the application must be weighed against the requirements of the manufacturing process. If the adhesive is applied in the optical path, light transmission and, where appropriate, refractive index are considerations, but there are also a number of other aspects to take into account.

Depending on whether the adhesive itself is to form an optical path or fill an optical gap, guide light into the gap or bridge the gap, a suitable viscosity of the adhesive must be chosen.

For some applications, such as the assembly of fiber optic connections or connectors, the hardness and elasticity of the cured adhesive material are important because the fiber connection usually needs to be ground or polished afterwards and should prevent movement of the fiber, even under mechanically demanding conditions.

All adhesives shrink in volume to some degree during the curing process, which can lead to mechanical stress in the components and affect their positioning or alignment. While standard epoxy adhesives usually show a shrinkage in the magnitude of low single percent digits, special UV-curable adhesives reduce the volume by far below 1% while maintaining optical transparency.

The outgassing of adhesive material or solvents during application as well as during or even after curing can also play a role, not only because of possibly harmful processes for the optical components but also because the gases can be relevant to health. During processing, fume extraction systems can provide a solution.

This series’ high refractive index (RI) helps to miniaturize optical components. Resin type #18210 features a refractive index of more than 1.7 and contains solvent, good for creating a thin film (<1 µm). Solvent-free resin type #18247 enables to produce thicker layers (>2 to 3 µm) and can create nano-size patterns without a pre-baking process to evaporate the solvent. This product maintains a high refractive index of 1.689 to 1.765, depending on the light’s wavelength, keeping a high transparency in the visible wavelength range by using non-organic fillers. With the recent increase in the refractive index of glass for AR/VR, aimed at expanding the field of view, the demand for resins to match this higher RI is also increasing. Just recently, NTT-AT has developed new 1.8 and 1.9 refractive index resins with high transparency and good nanoimprintability, able to fabricate a uniform thin film by spin coating. These resins are expected to contribute to the improvement of the flexibility in optical design. NTT-AT uses high-precision refractive index control technology in the manufacture of optical adhesives to increase the concentration of high-refractive-index inorganic nanofillers and achieve high refractive index while optimizing the resin formulation. These resins are compatible with high-refractive index glasses and can create nano-patterns with a line width of 50 nm to 10 µm by nanoimprinting.

NOA 133 Optical Adhesive 1oz bottle

Refractive Index 1.33; 15 cps Viscosity at 25°C Norland Optical Adhesive 133 is clear liquid adhesive that will cure when exposed long wavelength ultraviolet light. NOA 133 is recommended for bonding for glass to glass. Adhesion is also good to cellulose acetate butyrate. NOA 133 is cured by ultraviolet light between 320 to 450 nm. Full cure requires 6 Joules/cm 2. The adhesive exhibits oxygen inhibition when used as a coating. To overcome this the adhesive must be cured under an inert atmosphere, such as nitrogen. When used as a coating the liquid adhesive's temperature must be kept below 9C to prevent vaporization.Typical Properties of NOA 133 Temperature Range -15°C to 90°C Keep NOA 133 in a coo l(5-20°C) dark place. If refrigerated, allow the adhesive to come to room temperature before using.
