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.

These adhesives can be polished after assembly. NTT-AT’s AT9575M (epoxy) and AT8105 (acrylate) adhesives for optical fiber fixing have gained popularity for their good workability as non-fluid adhesives. NTT-AT has executed durability tests that have shown no peeling of a fiber array after 2,000 hours at +85 °C and 85% of humidity. With viscosities that are appropriate for the usage location, the adhesives for fiber array assemblies are easy to use. While the adhesives for fixing v-grooves show fluidity, the optical fiber fixing adhesives’ consistency is that of a paste, suitable for protecting the fiber. 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.
