Chapter 1

Setup

Overview

The HL-3 Series of Halogen Calibrated Light Sources for the VIS-Shortwave NIR (350nm-1100nm) is a
tungsten-halogen light source that provides known absolute intensit y values at several wavelengths,
expressed in µW/cm²/nm. Since the spectral intensity of the HL-3 Series can be traced to an intensity
standard traceable to the N ational Inst itute of Standards and Te chnology (N IST), it is specifically
designed for calibrating the absolute spectral response of your system.

Note

If you have a spectr o met er se tup tha t is high ly sensitive, you may oversatura te it.

Models Available

HL-3 Series light source models are available in regular (350 – 1100 nm) and extended (EXT models)
(350 – 2400 nm) wavelength ranges. The INT models are used with an i ntegrating sphere (rat her than a
CC-3 cosine-corrected ir radiance probe). The following models are available in the HL-3 Series:

Model Calibrated Wavelength Range Minimum Uncertainty

Level

HL-3-CAL 350 – 1100 nm 10% No
HL-3-CAL-EXT 350 – 2400 nm 10% No
HL-3-INT-CAL 350 – 1100 nm 15% No
HL-3-INT-CAL-EXT 350 – 2400 nm 15% No

In addition the following plus ver sions are available which reduce the percentage of uncertainty to 3%
and offer a shutter :

Unpacking the HL-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 th e instrument and make sur e that there is no dama ge. Do not us e the

instrument if damage is present.

3. Use this instrument in a clean laboratory environment (see Operating Envi ronment

2 000-10000-190-02-201308

).

1: Setup

Contents

Your HL-3 Series Light Source package should contain the following:

 HL-3 light source unit
 1 AC adapter for stabilizing power
 Power cord
 Lamp Calibration Report for usin g the HL-3 light source with a CC-3 cosine-corrected irradiance

probe or integ ra tin g sph e re (INT mod el s)

 1 CD that holds files for both lamp calibration reports
 1 Allen wrench for adjusting the inner barrel of the SMA connector and CC-3 cosine corrector

Connecting a Spectrometer to the HL-3

Before using an HL-3 S eries light source for the first time, ch eck for tran sport damage. Be sure to adhere
to all warnings on the unit and in this operat ional manual. Make sure you have your HL-3 light source,
your spectro met er, a CC -3 cosine-corrected irradi ance probe o r i ntegrating sphere, and Ocean Optics
spectromet er op erating software.

The procedure will differ, depending on whether you are using a cosine corrector or an integrating sphere
(INT models).

Connecting a Spectrometer to the HL-3-CAL Models When Using a Cosine Corrector

► Procedure

Use the following pro cedure to connect you r HL-3 light source to a spectro meter when using a co sine
corrector:

1. Loosen the set screw on the HL-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 w a y into the HL -3's SMA connector, taking the place of the SMA's inner barrel.

3. Tighten the setsc rew on the SMA conn e cto r of the H L-3 with an Allen wrench . Connect the other

end of the fiber into the SMA connector of the spectrometer.

4. Plug the switching AC adapte r into the bac k of the HL-3. The adapter stabilizes power coming

into the la mp to ensure constant spectral intensity.

5. Plug one end of the p ower cord into the AC adapter and the other end into a standard outlet.

6. Turn the lamp on. Allow the lamp to warm up for at least 15 minutes before using it. Pla ce th e

HL-3 horizontally.

7. Insert the cal ibration disk that came with your light s ource into your computer. This disk contains

one ASCII file with the same in formation as the Lamp Calibration Reports that came with your
HL-3. The file name con tains the l amp's serial number, followed b y .LMP. Copy these files to
the desired directory on your computer.

8. Start your spect r om eter op e ra tin g software. S ee your spectrometer manual for instructions on

calibrating the spectrometer with the HL-3.

Connecting a Spectrometer to the HL-3-INT-CAL Models When Using an I ntegrating Sphere

► Procedure

Use the following pro cedure to connect you r HL-3 light source to a spectrometer when using an
integratin g sph e re ( INT models):

1. The HL-3-CAL-INT and HL-3-CAL-INT-EXT h a ve a diffu s or for li ght ou tpu t. P l ace the HL-3-

CAL-INT output diffusor a t the aperture of your integrating sphere. The minimum aperture
diameter of your integrating sphere should be 6 mm. The HL-3-CAL-INT is validat ed f or any
larger Aperture diameters up to 30 mm. The HL-3-CAL-INT has to be placed in a vertical
orientation. 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 HL-3's SMA connect or, taking the place of the SMA's
inner barr el.

2. Tighten the setsc rew on the SMA conn e cto r of the HL-3 with an Allen wrench. Connect the other

end of the fiber into the SM A connector o f the spectrometer.

3. Plug the switching AC adapter into the back of the H L-3. The adap ter stabilizes power coming

into the la mp to ensure constant spectral intensity.

4. Plug one end of the power cord into the AC adapter and the other end into a standard outlet.

5. Turn the lamp on. Allow the lamp to warm up for at least 15 minutes before using it.

6. Insert the cal ibration disk that came with your light source into your computer. This disk contains

one ASCII file with the same information as the Lamp Calibrat ion Reports that came with your
HL-3. The file n ame contains the lamp's serial number, followed by .LMP. C opy these files to
the desired directory on your computer.

7. Start your spectro met er op era tin g so ftw a re. Se e you r spec tr om ete r man ual f or in st ru cti ons on

Tips

When you perform measurement s with the calibrated spectrometer system, record a new
dark spectr um before e ach measurement. Th is minimizes the influence of a shifted dark
spectrum.

Use a log to monitor the op eration time of the light source. Recal ibration of the light
source after 50 hours of operati on is recommended. A sample log is provided in

Calibration Basics

Overview

Calibrated systems, independent of the particular calibrated un it, 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 f or the same
calibrated u nit.

Each measu rement result has an un certainty, and the level of uncertainty is given either for one single
standard deviation (k = 1) or for two standard de viations (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 b y the metrologist
following a previously defined and proven calibration procedure. Clear documentation of the calibration
setup and of the calibrated devices used is an indispen sable require men t.

Calibration for Absolute Irradiance: Models HL-3
plus-CAL, HL-3 plus-CAL-EXT, HL-3-CAL and HL­3-CAL-EXT

Absolute irradiance has the physical u nit µW/nm/c m^2. The interpretation is as follows: This is the
wavelength resolved electromagnetic radiation which is emitted through an area [cm^2].

More detailed information can be found at:

http://oceanopticsfaq.com/category/calibrations/radiometric_calibrations/

Calibration for Radia nt Flux

Radiant flux has the physical unit µW/nm. It reflects the total amount of emitted electromagnetic
radiation from a light source and is typically r ealized by placing a light source inside an integrating
sphere. Th e HL-3 plus-INT models are used to calibrate the integrating sphere with an attached
spectrometer.

A: Calibration Basics

Uncertainty Level Calculati on f or HL-3 plus Family

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 uncert aint y. The
uncertainty should be validated seriously since th is reflects how reliab le the calibration is. T he following
internation al st an d ards define the uncertainty and are describing how the uncertainty should be derived:

• IEC Guide 115 Application of uncertainty of measurement to conformity asses sment a ctiv it i es in

the electrot echn i c al sec t or.

• 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 HL-3 plus-CAL on an ab so lut e irr ad i a nce s ca le 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 th e individual calibration certificate for your light source. The calibration certificate
contains m or e detailed information.
