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 pr ovides 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 Nationa l Institute of S tandards and Technology (NIST), it is
specifical l y desi gned f or ca libr at ing the absolute sp ect r al re sponse of your s ystem .

Note

If you have a spectr o met er se tup tha t is high ly sensitive, you may not be able to use the
DH-3 Series as a calibration 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 th e outside of the instrum ent and make sure that there is no damage. Do not u se the

instrument if damage i s 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 corre ctor

2 000-10000-191-02-201309

1: Setup

Connecting a Spectrometer to the DH-3

Before using a DH-3 Series light source for the first time, che c k for tr an sp ort d a ma g e. Be sur e to ad he re
to all warnings on the unit and in this operational manual. Make sure you have your DH-3 light source,
your spectro met er, a CC -3 cosine-corrected irradiance probe, an d Ocean Optics spectr ometer 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 wa y into the DH-3's SMA connector.

3. Tighten the setsc rew on the SMA conn e cto r 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 po wer cord.

5. Turn the lamp on using the ON/OFF switch on the bac k of th e li gh t sou r ce.

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 nam e contains th e lamp's se rial number, followed by CC.LMP. Copy these files
to the desired directory on your computer.

9. Start your spect r om eter op e ra tin g 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 spectr um before each measurement. Thi s minimizes the influence of a shifted dark
spectrum.

Use a log to monitor the operation time of the light sou rce. Recalibration of the light
source after 50 hours of operation is recommended. A sample log is provided in
Appendix B: DH-3 Use Log

Calibration Basics

Overview

Calibrated systems, independent of the particular calibrated unit, are always traceable to national
standards. A c ali br at ed i tem is c omp ar ab l e to all calibrated items which are calibrated for th e same
calibrated u nit.

Each measu rement resu lt has an uncertainty, an d the level of uncertainty is given eith er for one sin gle
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 ca lib ra ti on h as to be done by th e metrologi st
following a previously defined and proven calibration procedure. Clear documentation of the calibration
setup and of the calibrated devices used i s an ind i spensable requ ir em ent.

Calibration for Absolute Irradiance

Absolute irradiance has the physical unit µW/nm/cm^ 2. The interpre tation is as follows: This is the
wavelength resolved electromagnetic radiation which is emitted through an area [cm^2].

When you attach a co sin e c or r ec tor c or re ctly at the mounting o f th e ligh t source then th e amount of light
has a defined electrom agnetic radi ation power per surface area of your cosine corrector.

Uncertainty Level Calculati on f or DH-3 plus-BAL­CAL

Each realist ic me a sur e men t has an un cer ta in t y and ther ef o re, a calibration has an uncertainty. The
uncertainty should be validated seriously since this reflects how reliable the calibration is. The following
internation al st an d ards define the uncertainty and are describing how the uncertainty sh ould be derived:

• IEC Guide 115: Application of uncertainty of measurement to conformity assessment activities in

the electro technical sector.

000-10000-191-02-201309 6

A: Calibration Basics

• JCGM100:2008: GUM 1995 with minor corrections

Ocean Optics calibrations are done in relation to these international stand ards.
Ocean Optics provides a calibration of the DH-3 plus-CAL on an ab so lut e irr ad i an ce s cal e in

µW/nm/cm^2. The sources of uncertainties taken into account are listed below in the example. The actual
values are l isted in the individual calibration certificate for your light source. The calibration certif i cate
contains m or e detailed info rmation.
