NEW PRODUCT

The FABRY-PERUS is a high-performance optical interrogator designed for high-frequency measurements in environments where traditional electronic sensors fail. It is uniquely optimized for Extrinsic Fabry-Perot Interferometer (EFPI) sensors, providing a robust solution for high-precision pressure monitoring. Driven by a powerful 5mW SLD source (1550 nm) and a high-resolution I-MON 256 C spectrometer, the unit delivers laboratory-grade performance with an optical input range of -70 to -22 dBm. Its internal 8-way optical switch uses 2 channels for continuous self-calibration and background noise normalization, ensuring exceptional long-term stability. Whether used for integrated P+T probes or complex FBG arrays, the Fabry-Perus offers the speed and flexibility required for advanced R&D and industrial monitoring.
