NA-F Optical Fiber Numerical Aperture Measurement System

The NA-F Optical Fiber Numerical Aperture Measurement System is a high-precision instrument developed by the Shanghai Electric Cable Research Institute (SECRI) for measuring the numerical aperture (NA) of optical fibers. The system uses the far-field optical distribution method combined with digital phase-locked technology and advanced opto-mechanical-electronic integration to provide accurate and reliable numerical aperture measurements for optical fibers.

The system is capable of measuring optical fibers with a maximum numerical aperture greater than 0.35. It offers a measurement resolution of ≤0.5° and repeatability of ≤0.005, ensuring highly consistent and precise test results for research, manufacturing, and quality control applications.

In addition to the measurement system, SECRI provides a range of optical fiber preparation and testing tools to support laboratory and production testing. These include precision fiber cleavers, fiber coating strippers, longitudinal cable cutters, Kevlar scissors, armored cable strippers, V-groove fiber connectors, drop cable strippers, and single-port and dual-port fiber coating stripping tools for efficient sample preparation.

The NA-F system is suitable for optical fiber manufacturers, testing laboratories, and research institutions that require accurate, repeatable, and standards-based measurement of optical fiber numerical aperture.
