Chapter 1
Setup
Overview
The DH-3 Series of Halogen Calibrated Light Sources for the UV-VIS-Shortwave NIR (230nm-1100nm)
is a deuterium and halogen light source that provides known absolute intensity values at several
wavelengths, expressed in µW/cm²/nm. Since the spectral intensity of the DH-3 Series can be traced to an
intensity standard traceable to the National Institute of Standards and Technology (NIST), it is
specifically designed for calibrating the absolute spectral response of your system.
Note
If you have a spectrometer setup that is highly sensitive, you may not be able to use the
DH-3 Series as a calibration source.

The following sections provide instructions on unpacking and setting up your DH-3 Series Light Source.
Unpacking the DH-3 Series Light Source
►Procedure
1. Unpack your lamp assembly and power supply carefully. Although the lamp is rigidly mounted,
dropping this instrument can cause permanent damage.
2. Inspect the outside of the instrument and make sure that there is no damage. Do not use the
instrument if damage is present.
3. Use this instrument in a clean laboratory environment (see Operating Environment).
Contents
Your DH-3 Series Light Source package should contain the following:
DH-3 light source unit
Power cord
Lamp Calibration Report for using the DH-3 light source with a CC-3-UV-S cosine-corrected
irradiance probe
1 CD that holds files for lamp calibration reports
1 Allen wrench for adjusting the cosine corrector

1: Setup
000-10000-191-02-201601 3
Connecting a Spectrometer to the DH-3
Before using a DH-3 Series light source for the first time, check for transport damage. Be sure to adhere
to all warnings on the unit and in this operational manual. Make sure you have your DH-3 light source,
your spectrometer, a CC-3 cosine-corrected irradiance probe, and Ocean Optics spectrometer operating
software.
►Procedure
Use the following procedure to connect your DH-3 light source to a spectrometer:
1. Loosen the set screw on the DH-3's SMA connector.
2. Screw the CC-3 cosine corrector onto the end of the fiber. The connection should be tight. Insert
the CC-3 all the way into the DH-3's SMA connector.
3. Tighten the setscrew on the SMA connector of the DH-3 with an Allen wrench. Connect the other
end of the fiber into the SMA connector of the spectrometer.
4. Plug in the power cord.
5. Turn the lamp on using the ON/OFF switch on the back of the light source.
6. Turn on the deuterium light and the halogen light on the front of the light source.
7. Allow the lamp to warm up for at least 15 minutes before using it. Place the DH-3 horizontally.
8. Insert the calibration disk that came with your light source into your computer. This disk contains
one ASCII file with the same information as the Lamp Calibration Reports that came with your
DH-3. The file name contains the lamp's serial number, followed by CC.LMP. Copy these files
to the desired directory on your computer.
9. Start your spectrometer operating software. See your spectrometer manual for instructions on
calibrating the spectrometer with the DH-3.
Tips
When you perform measurements with the calibrated spectrometer system, record a new
dark spectrum before each measurement. This minimizes the influence of a shifted dark
spectrum.
Use a log to monitor the operation time of the light source. Recalibration of the light
source after 50 hours of operation is recommended. A sample log is provided in
Appendix B: DH-3 Use Log.

Appendix A
Calibration Basics
Overview
Calibrated systems, independent of the particular calibrated unit, are always traceable to national
standards. A calibrated item is comparable to all calibrated items which are calibrated for the same
calibrated unit.
Each measurement result has an uncertainty, and the level of uncertainty is given either for one single
standard deviation (k = 1) or for two standard deviations (k = 2), which is often named as expanded
uncertainty.
A calibrated device should give trusted results; therefore, the calibration has to be done by the metrologist
following a previously defined and proven calibration procedure. Clear documentation of the calibration
setup and of the calibrated devices used is an indispensable requirement.
Calibration for Absolute Irradiance
Absolute irradiance has the physical unit µW/nm/cm^2. The interpretation is as follows: This is the
wavelength resolved electromagnetic radiation which is emitted through an area [cm^2].
When you attach a cosine corrector correctly at the mounting of the light source then the amount of light
has a defined electromagnetic radiation power per surface area of your cosine corrector.
More detailed information can be found at: http://oceanoptics.com/frequentlyaskedquestions/light-
sources-radiometric/
Uncertainty Level Calculation for DH-3 plus-BAL-
CAL
Each realistic measurement has an uncertainty and therefore, a calibration has an uncertainty. The
uncertainty should be validated seriously since this reflects how reliable the calibration is. The following
international standards define the uncertainty and are describing how the uncertainty should be derived:
IEC Guide 115: Application of uncertainty of measurement to conformity assessment activities in
the electrotechnical sector.
JCGM100:2008: GUM 1995 with minor corrections
Ocean Optics calibrations are done in relation to these international standards.

A: Calibration Basics
8000-10000-191-02-201601
Ocean Optics provides a calibration of the DH-3 plus-CAL on an absolute irradiance scale in
µW/nm/cm^2. The sources of uncertainties taken into account are listed below in the example. The actual
values are listed in the individual calibration certificate for your light source. The calibration certificate
contains more detailed information.

calibration have a temperature range of 19 °C to 25 °C. The humidity might

d
Uncertainty in mounting distance [d] of the used cosine corrector. 1.8 % per

used to calibrate the light source. [D_Lamba[QE]=0.3 nm,
D_Lambda[NirQ512]= 1 nm]

Optics working standard. See calibration certificate for details.
7.

light source.
8.
T_TEC_
Influence of the sensor temperature [TEC] of the spectrometer which was used
to calibrate the light source.
9.
Dark
Influence from uncertainties of the measured dark level of the spectrometer
used to calibrate the light source.
10.
Rep
Reproducibility of the used spectrometer system for calibration.
11.
