Arden nPA-400 Fiber Refractive Index Profile Tester
The nPA-400 is a fast, easy and cost-effective way to obtain refractive index data for verifying standard and specialty fibers.
The clean, efficient graphical user interface allows users to fully characterize their fiber with minimal training or experience. nPA-400 provides accurate and repeatable refractive index data, providing valuable information about fiber design and manufacturing processes.
The nPA-400 Refractive Index Analyzer uses improved refractive near-field techniques to analyze the grayscale intensity distribution of an optical fiber in end view to determine its complete 2D refractive index distribution.
