Adhesives for Fiber Array Assemblies

Viscosity 36,000, 180,000 mPas; Bending Adhesion Strength >114, >128 kgf/cm²; UV Curing Conditions 100 mW/cm², 2 min; Curing Shrinkage Rate 0.5%, 0.9%; Tg +195, +233 °C; Thermal Expansion Coefficient 18, 20 ppm/°C NTT-AT’s high-precision optical adhesives allow easy fixation of optical components with sub-micron accuracy. Based on epoxy, these high-precision optical adhesives are available with low viscosity of 36,000 mPas (AT3916P) or with high viscosity of 180,000 mPas (AT3862P). Both adhesives show minimal position changes due to curing time and temperature. Shrinkage rate during curing is very low for this series of high-precision optical adhesives, and the thermal expansion coefficient is small. Using ultraviolet (UV) ray curing makes alignment easy. NTT-AT’s series of high-precision adhesives show excellent durability: Even after a high-temperature process at +260 °C, the adhesives’ bonding strength does not change. And no peeling occurred after 200 cycles in a simplified heat cycle test. In order to achieve high reliability, a product must clear the tests conducted by the users themselves. If you have had even just a bit of dissatisfaction in precision or durability results in the past, please put NTT-AT’s high-precision adhesives to the test. In case you need any consulting regarding issues related to adhesion, please contact the AMS Technologies optical adhesives experts to discuss the detailed challenges of your application.

Refractive Index 1.315; 15 cps Viscosity at 25°C Norland Optical Adhesive 1315 is clear liquid adhesive that will cure when exposed long wavelength ultraviolet light. NOA 1315 is recommended for bonding for glass to glass. Adhesion is also good to cellulose acetate butyrate. NOA 1315 is cured by ultraviolet light between 320 to 450 nm. Full cure requires 6 Joules/cm 2. The adhesive exhibits oxygen inhibition when used exposed to air. 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 1315 Temperature Range -15°C to 90°C Keep NOA 1315 in a cool ( 5 to 20°C) dark place. If refrigerated, allow the adhesive to come to room temperature before using.

 Refractive Index 1.56; 200 cps Viscosity at 25°C Norland Optical Adhesive 71 ("NOA71") is an optically clear, liquid adhesive that will cure when exposed to long wavelength ultraviolet light (10g syringe). The adhesive is a one-part, 100% solids material that offers advantages in bonding applications that require optical clarity or require fast cure times and long term stability over a wide range of temperatures. The use of NOA 71 eliminates premixing, drying, or heat curing operations common to other adhesive systems.NOA 71 was formulated to provide a strong bond to glass surfaces. This adhesive can also be used for adhering to other substrates, such as metal, fiber- glass, and glass filled plastics. Typical applications are laminating solar cells, holographic plates, flat panel displays and touch screens or as a clear coating on plastic or metal.NOA 71 is cured with long wavelength UV light from 315 to 400 nanometers with peak absorption at 365 nm. The amount of energy required for full cure is 3.5 Joules/sq. cm of UV light. Typical Properties of NOA 71 Solids 100% Elongation at Failure 43% Modulus of Elasticity (psi) 55,000 Tensile Strength (psi) 1,300 Hardness - Shore D 86 Dielectric Constant (1 MHz) 4.0 Dielectric Strength (V/mil) 456 The shelf life of NOA 71 liquid is at least 4 months from the date of shipment if kept in a cool (5-22° C), dark place in the original container. If refrigerated, allow the adhesive to come to room temperature prior to use.

Try NTT-AT’s series of adhesives for optical waveguides! Within this series you find acrylate-based adhesives (AT6001, AT8224)with excellent durability that have cleared a large number of reliability tests. Epoxy adhesives are also part of this series, with a refractive index that can be accurately controlled within a range of 1.456 to 1.567 (±0.005, Na-D) – or with a fixed refractive index that is the same as quartz to deliver low reflectance (GA700L, GA700H). UV curing of the adhesives for optical waveguides allows for adhesion in a short time frame and makes alignment easy. The adhesives withstand a solder reflow process for Si Photonics (+260 °C). In order to achieve high reliability, a product must clear the tests conducted by the users themselves. If you have had even just a bit of dissatisfaction in reliability test results in the past, please put NTT-AT’s adhesives for optical waveguides to the test.
