Optical Sensing Instrument | si255
Description
Key Features
The si255 is an industrial grade fan-less optical sensing interrogator.
Featuring both static and dynamic full spectrum analysis, the si255 provides
long-term, reliable and accurate measurements of nearly 1000 sensors on 16
parallel, 160 nm wide channels.
Full spectrum at 1 kHz with 160 nm or 5 kHz with 80 nm on 16 parallel channels
simultaneously, eliminating the need for optical switches
The si255 features an all new, high power, low noise, ultra wide swept wavelength
laser with guaranteed absolute accuracy on every scan which is realized with
Micron Optics patented Fiber Fabry-Perot filter and wavelength reference
technology.
The all new HYPERION platform, on which the
si255 is based, features new and
groundbreaking capabilities including highperformance on-board DSP and real-time FPGA
processing. This enables rapid full-spectrum
data acquisition and flexible peak detect
algorithms of Fiber Bragg Gratings (FBG), Long
Period FBGs and Fabry-Perot (FP) sensors with
low-latency access to data for closed loop
feedback applications.
Dynamic and absolute
measurements of
FBG & FP sensors on
16 parallel,160 nm wide
channels and
ENLIGHT compatible.
The HYPERION platform is now compatible with ENLIGHT, Sensing Analysis
Software, which provides a single suite of tools for data acquisition, computation,
and analysis of optical sensor networks. More
information on ENLIGHT can be found here.
The HYPERION platform also includes a
comprehensive fully supported
Application Programing Interface
(API) and LabVIEW, Python, Matlab,
C# and C++ examples.
Dynamic and absolute measurements of FBGs, LPGs and FP optical sensors
from detailed optical spectrum
Single and continuous 25 dB dynamic range, available to each sensor on each
channel, independent of differential system losses
Data verification key guarantees only valid output. Each data set is calibrated
and verified against any potential sources of system error.
Proven reliability and longevity of the Micron Optics swept wavelength source,
with over 100 million hours logged since 2000

Per NIST Technical Note 1297, 1994 Edition, Section D.1.1.1,
2 definition of "accuracy of measurement.” Verified by HCN
cell and 1m patch cord.
Captures effects of long term use over full operating
3 temperature range of the instrument.
Per NIST Technical Note 1297, 1994 Edition, Sect D.1.1.2,
4 definition of "repeatability [of results of measurements]."
Dynamic range in peak detection mode is 30dB at 1Hz data
rate, 25 dB at 100 Hz scan rate and 20 dB at 1 KHz scan
5 rate. Dynamic range in full spectrum mode is defined as laser
launch power minus detection noise floor. 5kHz model runs at
5kHz only.
Used for performance qualification. FBG bandwidths of 0.1
6 to 1.0 nm are compatible, but some may reduce performance
or may require custom peak detection parameters.
Complies with the WEEE Directive 2012/19/EU for the
7 following European countries: UK, IT, DE, FR, NL, BE, ES, CH.
