Deep dive: Our CTO, Duane Dinkel, breaks down the core steps of fiber optic processing

Laser processing of optical fibers is a proven technology that offers highly controlled geometry formation over a wide range of fiber types while providing in-situ monitoring of angles, radii, beam emission profile, loss and other important parameters. Patented over 10 years ago by OpTek Systems, laser processing enables volume production of optical component designs once deemed impossible to fabricate. High-speed processing and low yield loss ensures competitive manufacturing costs.

Key advantages:

  • Rapid, non-contact processing
  • Accurate and repeatable feature positioning
  • Precise control over fiber and geometry
  • Broad range of end features and geometries
  • Optical-grade properties – no chipping, hackle, scratching
  • In-situ monitoring of optical properties and geometry
  • Enabling production ease of challenging fibers and designs

Fiber cleaving uses advanced laser technology to offer a precise and accurate alternative to traditional mechanical method.


The non-contact lensing process is an incredibly fast alternative to mechanical polishing and uses on-line imaging to ensure accurate centration of the lens to the fiber.

End Caps

Delivering optimum performance, created by fusion splicing or laser fusing short lengths of material to the fiber end face.


Laser stripping of optical fiber is the fast and accurate way to remove acrylate and polyimide coatings, in order to access the fiber for additional processing, termination, and packaging.
