Ocean Optics - Inventor of the World's First Miniature Spectrometer

 

XR-Series 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 ~200-1025 nm.

The XR Option is now available for our USB2000+, USB4000, our Enhanced Sensitivity (ES) USB Spectrometers and Jaz-EL200.

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 200-1025 nm, but thats only part of the story. The broad range doesnt 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. The Enhanced Sensitivity (ES) models have a special lens installed in the bench that increases efficiency in light collection.

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 m slit as the standard option in the XR-series Spectrometers?
Selecting a 25 m 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.
