Miniature Fiber Optics Spectrometers
The XR-Series of Extended Range
Spectrometers from Ocean Optics are responsive across a wide spectral
range, providing you an optical resolution of ~2.0 nm (FWHM) and the
convenience of a single, monolithic spectrometer to cover all
wavelengths from ~200-1050 nm.
The XR Option is
now available for our USB2000+, Jaz-EL200 and USB4000 Spectrometers and
in custom systems.
Special Grating Extends Wavelength Range
The ability to provide UV-NIR coverage in a single
miniature spectrometer has always been a challenge and daisy-chaining
multiple USB spectrometers is not always practical or convenient.
Enter the XR-Series. Thanks to its new 500 lines/mm
groove density grating, we can now offer our flagship spectrometers with
broader spectral coverage and good optical resolution. This grating
delivers 850 nm of spectral range and is blazed at 250 nm. Because their
optical bench designs are not affected, the USB2000+, Jaz-EL200 and
USB4000 experience no trade-off in performance with the new grating.
Preconfigured Broad-Range Options
Our XR gratings are integrated into three familiar
spectrometers - each preconfigured for general-purpose UV-NIR
applications.

Frequently
Asked Questions
What applications do
XR-Series Spectrometers suit? Solar irradiance measurements,
atomic emission line analysis, plasma
analysis, process applications and more.
How are you able to
provide the extended range option in
USB-series and Jaz Spectrometers? The new diffraction grating provides
coverage from 200-1050 nm, but that’s
only part of the story. The broad range
doesn’t do you much good if you are
unable to manage higher-order spectral
sorting. So we developed a proprietary
order-sorting filter that is applied
directly to the detector to eliminate
second- and third-order effects.
What spectrometer models are
available with the XR-1 grating? Our standard options will be
preconfigured versions of the USB2000+,
USB4000 and JAZ-EL-200. We may also be
able to accommodate custom
configurations in other USB spectrometer
models as well. Please contact an
Applications Scientist for details.
Why select a 25 µm slit as the
standard option in the XR-series
Spectrometers? Selecting a 25 µm slit allows us to
maintain good optical resolution across
the entire spectral range. Also, unless
your application involves low levels of
light, the slit width is appropriate.
Why would I choose an XR-series
Spectrometer versus the HR4000CG-UV-NIR? The HR4000CG is an excellent,
high-performance spectrometer,
especially if your application requires
sub-nanometer (<1.0 nm FWHM) optical
resolution. For some applications,
however, that extra performance – which
comes at a higher price -- may not be
necessary. With the XR-series
Spectrometers, broad-range coverage is
not limited to a single option.
