Adhesive for Optical Waveguides
Adhesive for Optical Waveguides

Adhesives for Optical Path Link-up. The adhesive technology used in optical communications is one of the key technologies we offer.

Benefits / Features

Characteristics

  • The refractive index can be accurately controlled within a range of 1.458-1.567±0.005 (Na-D).
  • Using ultraviolet ray curing makes alignment easy. Very little adhesion loss due to heat or moisture, providing high durability.
