Benefits / Features

Special adhesive technology, which is one of NTT-AT's key technologies, has advanced, along with optical communication technology, since 1993.
For the commercialization of high reliability optical parts, an adhesive is required which has excellent durability, in addition to application-specific optical characteristics and various other features.
To meet requirements of individual applications, NTT-AT supplies various types of adhesive, such as those with a specific refractive index, a capability of fixing with high precision, high heat resistance, high elasticity and low moisture permeation. In addition, NTT-AT can customize its adhesives to suit customers' needs.

1.Adhesive for Optical waveguides
Optical Adhesive used for PLC to Fiber Link-up Precision refraction index of 1.46-1.57±0.005 (Na-D) provides controllability. Ultraviolet curing makes alignment easy. Very little adhesion loss due to heat or moisture, providing high durability.
2.Array Assembly Adhesives
Excellent durability JJust the right viscosity for easy application
3.High Precision Adhesives
Minimal position changes due to curing time and temperature change allowing for even submicron order adhesion. AT9290F is transparent upon curing.
4.Sealant for Optical Parts
Low stress produced on inner parts during curing and heat cycle. Even at high temperatures moisture permeation is low.
5.Optical Waveguide Forming Resins
Excellent flatness and refractive index adjustment Products which can withstand the heat of soldering are also available for application to dielectric films between layers
6.Adjustable Refractive Index Resin
The refractive index can be adjusted over the range from 1.32 to 1.70 with +/-0.005 accuracy Excellent optical permeability
7.Nano Imprint Resin
High Accuracy Characteristics of Resin can be Customized High Light Transmittance
8.High Refractive Index / Low Refractive Index Resins
A refractive index of either 1.4 or less, or 1.7 or more can be chosen High transparency in visible light domains
