Description
The si720
is a high power, high accuracy, high-resolution complement to the Micron Optics
si425. It provides higher accuracy and resolution than
the si425 and can be used for a wide variety of fiber optic sensors. The
system provides users with a complete understanding of how the spectral shape
of the fiber Bragg grating sensors react to varying physical conditions - rather
than only reporting shifts in central wavelengths. This instrument is used both
as the first step in the development of high-volume custom sensing systems and
in long term field measurements. Applications
-
Useful in the design and selection of fiber Bragg
grating based sensors for strain, temperature, pressure, etc.
-
High
accuracy, resolution and full profile data provide comprehensive feedback on fiber
Bragg grating and extrinsic Fabry-Perot sensor capabilities
-
Both
built-in and LabVIEW™ peak detection functions provide high resolution, high
accuracy fiber Bragg grating center wavelength measurements
-
Full-spectrum
measurements aid in understanding how sensors' characteristics change under various
physical conditions
-
Useful for analysis of a
wide variety of passive optical sensors - FBGs, Fabry-Perot sensors, Long Period
Gratings, and more
Benefits
-
Two
input detection channels coupled with a powerful and extremely low-noise fiber
ring laser allow simultaneous monitoring of more than 100 sensors per channel
-
Dual-detector design enables either input channel
to measure FBGs in transmission or reflection -
System
can be quickly adapted to interrogate many types of sensors -
Laser
is continuously swept across an 80 nm spectrum at user-selectable rates of 5.0
or 0.5 Hz -
Automatic calibration is achieved with
every scan using an integrated NIST-traceable absolute wavelength reference
-
Combination of absolute wavelength reference and
proprietary Micron Optics instrument design provides a stunning and reliable wavelength
repeatability of 0.05 pm and a wavelength accuracy of 1 pm -
Fast
analog-to-digital conversion and proprietary LINUX-based software -
Built-in
single board computer, display and instrument control panel
