The Arden Photonics nPA-400 Refractive Index Profiler uses a modified refracted near-field technique to analyze a fiber end-face to determine the full 2D refractive index distribution.
Arden Photonics nPA-400
Advantages
The nPA-400 is the quick and easy way to get the refractive index data you need to verify your specialty fiber design and manufacturing processes.
Obtain complete 2D refractive index profiles (RIP) of your fibers in seconds. Able to analyze both standard and specialty fibers up to 400 µm diameter. The user-friendly GUI and the minimal fiber preparation required make the nPA-400 the perfect tool to get fast, repeatable RIP characterizations of your fibers.
There is no need to rotate the fiber or scan the fiber end face, resulting in a very fast measurement, meaning that the nPA-400 is suitable for production lines, research and development labs, or QA environments.
