In the field of optoelectronics products BANDO offers highest quality for polishing films.

BANDO Chemical Industries has realized the creation of nanoparticles characterized with
“uniformly and flexibly controlled particle sizes” and “superior dispersion stability”, by using the company’s original technologies of combination design and purification of the nanoparticles.

TOPX polishing films

With these technologies, we provide precision polishing products realizing high grinding force and high surface grinding accuracy.

Advantages

  • Combines high grinding capability and surface precision
  • High precision surfaces are possible due to the small abrasive grains diameter
  • High grinding capability reduces grinding time
  • Long life reduces costs

Application

  • Polishing of optical fiber end faces and related products
  • Polishing of fiber isolator parts
  • Other high precision polishing requirements
