NTT-AT provides detailed solutions that meet customers' needs for various types of optical adhesive.

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.
