Outsourcing YOUR Interferometry Needs | +/- $20K Savings |
Interferometer Test Services are sometimes available for outsourcing your “Batch Jobs”. Let me know if you need to “batch” process measurement requirements that support Ø1.25 mm to Ø2.50 mm Ferrule PC/APC Single-Fiber Connectors. I have Customers that will “Batch Jobs” when their normal production permits. Outsourcing with a Norland Non-Contact CC6000 will provide repeatable accurate measurements for the Radius of Curvature, Apex Offset of Polish, and Fiber Undercut or Protrusion.
The Norland CC6000 (now Thorlabs) provides crucial quality information needed to assure long-term performance of fiber optic connectors i.e. IEC; Telcordia. Single-fiber connector measurement printouts are provided. (See Report below) If your Job requires these specifications you have no choice but to buy an Interferometer or outsource your interferometry requirements.

It’s helpful to understand that optical fiber manufacturers pay close attention to specific geometric parameters. It’s important for them to maintain the stated tolerances (the exact physical dimensions) so the optical fiber will provide repeatable results.
Norland CC6000 PC/APC Interferometer measures:
| Measured parameters | Range | Reproducibility | Repeatability |
| Radius of Curvature | 3 mm –50 mm | 2.0% | 1% |
| Apex Offset | 0-100 microns | 4 microns | 2 micron |
| Fiber Height | +/-160 nm | 10 nm | 5 nm |
NOTE: Concentricity and Eccentricity are relative to core or ferrule and can seriously impact process controls.
- Core-to-clad concentricity: In fiber optics, the core is the transparent section of the glass (or plastic) fiber. The core has a high refractive index through which the light travels by internal reflections. Core-to-clad concentricity is a measure of the relationship between the geometric center of the core of an optical fiber and the geometric center of the cladding. In other words, core-to-clad concentricity measures how centered the core is in the optic fiber.
- Clad diameter: Fiber optic cladding is a layer of glass (or other material) surrounding the core of the optic fiber. The cladding has a refractive index that is slightly lower than the core and forms a conduit that carries light through the fiber.
- Mode field diameter: This is the diameter of optical energy in a single-mode fiber. Because the mode field diameter (MFD) is greater than the core diameter, MFD replaces the core diameter as a practical geometric parameter.
