Fiber Coupled Detectors
Inline No-Gap Tap Power Monitor
Our ILPM Series Fiber Optic Tap Power Monitors deliver unmatched performance for in-line optical power measurement and precision power control. They feature ultra-low insertion loss, high directivity, high power handling capability, minimal polarization and wavelength dependence, and low cost. The ILPM Series is based on a patented design that taps a portion of light through a groove formed along the side of a continuous optical fiber. This approach eliminates the need for lenses and optical coatings typically used in conventional fiber tap monitors, resulting in superior performance and reliability. The continuous-fiber structure is particularly well suited for compatibility with various fiber types, ultra-broad operating wavelengths, and high-power applications.
