Fiber optics for sensor, analysis, and measurement technology

j-fiber is a market leader in the field of high-quality, customer-specific fiber optical solutions for highly complex and demanding industrial and scientific applications. Our fibers are an excellent choice for:

  • Spectroscopic analysis of the optical properties and composition of solids, liquids, and gases
  • Fiber-optical measurement of physical, dynamic, and geometric properties (e.g. temperature, pressure, vibration, distance)
  • Applications in the DUV/UV-VIS spectral region and up to NIR
  • Singlemode and multimode applications

We offer

  • Broad choice for meeting customer’s optical requirements (numerical aperture, fiber geometry)
  • Application-specific cladding and jacket materials

Your advantages

  • Full bandwidth of special optical fibers from in-house production
  • Solutions for manufacturing and research from a single source
  • OEM and ODM partner
  • Joint development of prototypes for high-volume production
  • Global presence
