XE-1 Xenon
Calibration Light Source
Installation and Operation Instructions
Description
The XE-1 Xenon Calibration Source is a wavelength calibration source for UV-VIS-Shortwave NIR
spectrophotometric systems. The XE-1 produces Xenon lines from 916-1984 nm, and is an ideal lamp
to use when performing fast, accurate spectrometer wavelength calibrations.
The XE-1 features an SMA 905 Connector for interfacing with our optical fibers. It operates with a 12
VDC power supply (included with the unit) or 9V battery (not included).
The following sections detail the features of the XE-1 Xenon Calibration Light Sources.
XE-1 Xenon Calibration Light Source
Note
The XE-1 is NOT designed to operate as an excitation source in your experiments.
Spectral lines above 922 nm are not easily detectable by Ocean Optics spectrometers.

XE-1-CAL Installation and Operation Instructions
2 008-00000-XE1-01-1209
Parts Included
The XE-1 package includes the following items:
XE-1 Xenon Calibration Light Source
12 VDC power supply
WARNING
The beam emerging from the light source contains UV radiation that can cause
serious eye injury upon direct contact with the eye. Never look directly into the
light source.
The SMA 905 Connector may get extremely hot during operation. After lamp
use, allow sufficient time to cool before handling.
Dangerous voltages are present, and there are no user-serviceable parts inside.
Never open the XE-1.
Additional Accessories
The following are additional accessories available from Ocean Optics that you may need, depending
on your system set-up:
Spectrometer
SMA-terminated optical fiber
Ocean Optics software
Connecting the XE-1
Follow the steps below to set up your XE-1 for use.
►Procedure
1. Plug the 12 VDC power supply into a power outlet, then connect the barrel connector of the
power supply to the power input on the rear of the XE-1.
or
Alternately, you can use a 9-volt battery (not included) to power the XE-1. Open the battery
hatch of the XE-1 and install the 9-volt battery, and then proceed to Step 2.
2. Connect a fiber to the SMA 905 Connector on the XE-1. If your spectrometer does not have
an entrance slit, use a 50 m diameter (or smaller) fiber. Larger fibers and slits result in
reduced optical resolution.

Note
If the spectrometer does not have a slit and your experiment requires you to use fibers
of varying diameters, you will need to perform a wavelength calibration after
changing fibers. You should perform a wavelength calibration each time you unscrew
the fiber from the spectrometer and change fiber size.
3. Move the On/Off switch on the XE-1 (next to the SMA 905 Connector) to the On position.
The red LED will illuminate to indicate that the XE-1 is powered on.
You have now configured the XE-1 for use.
Calibrating With the Light Source
The information in this section explains how to calibrate your spectrometer’s wavelength using the
XE-1 light source.
About the Wavelength Calibration
You are going to be solving the following equation, which shows that the relationship between pixel
number and wavelength is a third-order polynomial.

p= I+ C1 p+ C2 p2+ C3p3
Where
 = the wavelength of pixel p,
I= the wavelength of pixel 0,
C1= the first coefficient (nm/pixel),
C2= the second coefficient (nm/pixel2)
C3= the third coefficient (nm/pixel3)
You will be calculating the value for Iand the three Cs.
Calibration Requirements for Ocean Optics
Spectrometers
To re-calibrate the wavelength of your Ocean Optics spectrometer using the XE-1, you will need the
following items:
XE-1 Xenon Calibration Light Source
Ocean Optics spectrometer and its manual
An optical fiber (for spectrometers without a built-in slit, a 50-m fiber works best)
A spreadsheet program (Excel or Quattro Pro, for example) or a calculator that performs third-
order linear regressions

Strong XE Emission Lines by Wavelength (nm)
There are more emission lines shown below than printed on the label on the XE-1 housing. The label
is intended as a quick, convenient reference and does not list every XE emission line that exists.
Below is a list of wavelengths for Xenon (as well as Krypton and Neon). Wavelengths listed in blue
are the ones listed on the calibration lamp’s label.
