You are looking for PLC and fiber array adhesion with high reliability? 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.

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.

$High Refractive Index Optical Adhesives$

High Refractive Index Optical Adhesives

Refractive Index 1.603-1.720; Viscosity 9-7,000 mPas; Transmittance 72%-96%; Hardness 67-83 Shore D; Shear Bond Strength 35->280 kgf/cm²; UV Curing Conditions 10, 100 mW/cm², 5, 10 min; Tg +63-+113 °C With a typical refractive index of 1.5 in conventional optical adhesives, the problem of a high reflection loss arose in cases of adhesion with high refractive index glass and crystal materials. Utilizing its refractive index control technology and optical loss reduction technology, NTT-AT has developed optical adhesives with a high refractive index adjustable to 1.6 or more. By adding high refractive index fillers, NTT-AT is even able to manufacture resins with a refractive index of 1.9. These resins are aimed at usage in the fields of optical recording, display technology, optical energy uses, etc. In addition to this series, NTT-AT also provides high refractive index resins for nanoimprint applications. NTT’s high refractive index resins are excellent in transparency in visible light domains, with haze values of 1 or less, so it is expected that they are used as a coating agent for displays and similar products. Within this series, you find acrylate-based adhesives (#18165 and #6205) as well as epoxy adhesives (E3754 and E7200). To match the particular working environment of our customers, NTT-AT provides both ultraviolet (UV) and heat curing types. NTT-AT provides refractive index customized resins to meet each customer's needs. It is possible to respond to several kinds of requests such as with/without solvent or adjusting the viscosity. Please contact the AMS Technologies optical adhesives experts to discuss your customized refractive index matched optical adhesive solution. Key Features: Refractive Index of 1.6 or More Can Be Chosen High Accuracy of Refracting Index Control: ±0.005 Choice of Either Ultraviolet (UV) Curing or Heat Curing Method High Transparency in Visible Light Domains: Optical Transmittance 90% or More at 1 mm Thickness Refractive Index: 1.603 to 1.720 Viscosity: 9 to 7,000 mPas Transmittance: 72% to 96% Hardness: 67 to 83 Shore D Shear Bond Strength: 35 to >280 kgf/cm² UV Curing Conditions: 10, 100 mW/cm², 5, 10 min Glass Transition Temperature Tg: +63 to +113 °C Applications: High Refractive Index Coating Agents; Bonding High Refractive Index Crystal Materials; Bonding High Refractive Index Glass (for Camera Lenses, Eyeglass Lenses, etc.); Higher Efficiency Optical Input and Output Power; Efficient Conversion of Light Energy; Optical Recording; Display Technology
