Product selection
si155
The si155 is a fanless optical interrogator for industrial applications. It offers both static and dynamic full-spectrum analysis and delivers long-term, reliable and accurate measurements from hundreds of sensors on 4 parallel channels.
The system has an extremely low-noise high-power wave laser and guarantees absolute accuracy with every scan. The HYPERION platform on which the si155 is based offers groundbreaking functions, including high-performance on-board DSP and real-time FPGA processing. This enables fast full-spectrum data acquisition and flexible peak detection algorithms from fiber Bragg gratings (FBG), long-term FBGs and Fabry-Perot (FP) sensors with low latency for data access to closed-loop feedback applications.
- Full spectrum at 1 kHz with 160 nm simultaneously on 4 parallel channels, no optical switches required
- Dynamic and absolute measurements of FBGs, LPGs and FP optical sensors from a detailed optical spectrum
- Single and continuous 25 dB dynamic range, for each sensor in each channel, regardless of different system losses
- The data verification key guarantees valid output. Each data set is calibrated and checked for possible system error sources (shortly)
si255
The si255 is a fanless optical interrogator for industrial applications. It offers both static and dynamic full-spectrum analysis and delivers long-term, reliable and accurate measurements from almost 1000 sensors on 16 parallel channels. The system has an extremely low-noise high-power wave laser and guarantees absolute accuracy with every scan.

OEM Single Board Interrogator
The HYPERION single board interrogator is an optical high-performance measuring device that offers OEM systems perfect integration options. A full suite of software tools, usually available for high-end instruments only, is part of the many functions of the system.
The interrogator is derived from the HYPERION si155 platform and uses the advantages of the patented Fabry-Perot filter from Micron Optics and the wavelength reference technology.
It features breakthrough features, including high-performance on-board DSP and real-time FPGA processing that enables fast, flexible peak detection algorithms for Fiber Bragg Grating (FBG), Long Term Grating, Fabry-Perot (FP), Mach Zehnder (MZ) sensors and others with low latency for data access to closed loop feedback applications.
