Chapter 1
Setup
Overview
The HL-2000-CAL Halogen Calibrated Light Source for the VIS-Shortwave NIR (300nm-1050nm) is a
tungsten-halogen light source that provides known absolute intensity values at several wavelengths,
expressed in µW/cm²/nm. Since the spectral intensity of the HL-2000-CAL can be traced to an intensity
standard provided by 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
HL-2000-CAL as a calibration source.
Before using the HL-2000-CAL 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 HL-2000-CAL, your
spectrometer, an SMA-terminated optical fiber or CC-3 cosine-corrected irradiance probe, and Ocean
Optics OOIIrrad Irradiance Software.
The following sections provide instructions on unpacking and setting up your HL-2000-CAL Calibration
Light Source.

1: Setup
Unpacking the HL-2000-CAL
►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-2000-CAL package should contain the following:
 DL-2000-CAL unit
 1 Switching AC adapter for stabilizing power
 1 Power cord for supplying power to the power supply
 2 Lamp Calibration Reports; one for using the HL-2000-CAL with a bare fiber and one for using
the HL-2000-CAL with a CC-3 cosine-corrected irradiance probe
 1 disk that holds files for both lamp calibration reports
 1 Allen wrench for adjusting the inner barrel of the SMA connector

1: Setup
Connecting a Spectrometer to the HL-2000-CAL
►Procedure
Use the following procedure to connect your HL-2000-CAL unit to a spectrometer:
1. Loosen the set screw on the HL-2000-CAL's SMA connector
2. If using a bare fiber with the lamp:
Remove the inner barrel from the SMA connector (if using a bare fiber with the lamp). Screw this
connector barrel onto the end of your fiber. The connection should be tight. Insert the barrel/fiber
all the way into the HL-2000-CAL's SMA connector.
If using a fiber and cosine corrector with the lamp:
Remove the inner barrel from the SMA connector (if using a fiber and cosine corrector with the
lamp). Screw the CC-3 cosine corrector onto the end of the fiber. The connection should be tight.
Insert the CC-3/fibcr all the way into the HL-2000-CAL's SMA connector, taking the place of the
SMA's inner barrel.
3. Tighten the setscrew on the SMA connector of the HL-2000-CAL with an Allen wrench. Screw
the other end of the fiber into the SMA connector of the spectrometer.
4. Plug the switching AC adapter (the black rectangle-shaped box) into the back of the HL-2000-
CAL. This adapter stabilizes the power coming into the lamp to insure constant spectral intensity.
5. Plug one end the power cord into a standard outlet, then plug the other end of the power cord into
the back of the switching AC adapter.
6. Turn the lamp on. Allow the lamp to warm up for at least 15 minutes before using it.
Configuring the OOIIrrad Software
►Procedure
Use the following procedure to configure the OOIIrrad software that comes with your HL-2000-CAL:
1. Insert the disk that came with the HL-2000-CAL lamp into the computer.This disk contains two
ASCII files containing the same information as the Lamp Calibration Reports that came with the
HL-2000-CAL:
• One file has the calibration numbers for calibrating the spectral response of your system with
the lamp and a bare fiber. The file name contains the lamp serial number, followed by
FIB.LMP.
000-10000-060-02-0505 3

1: Setup
• One file has the calibration numbers when calibrating the spectral response of your system
with the lamp and a CC-3 cosine-corrector and fiber. The file name contains the lamp serial
number, followed by CC3.LMP.
2. Copy these two files into your OOIIrrad Irradiance Software directory.
3. Start OOIIrrad Irradiance Software and place the software in Scope Mode.
4. Choose the Select Lamp option from the Lamp menu. A window opens and prompts you to
choose the Lamp Calibration Report file that reflects your optical setup (see Step 1 for details).
5. Choose Configure Fibers from the Spectrometer menu. Enter the fiber diameter values for each
channel in your setup. If using a bare fiber, enter the fiber's diameter here. If using a fiber with a
CC-3 cosine corrector, enter 3,900.
Note:
Whatever optical setup you wish to use for your application, you must also use for
calibrating the spectral response of your system. For example, if you are going to use a
200 µm fiber with a CC-3 cosine corrector for your application, you must use the same
200 µm fiber and CC-3 for calibrating the spectral response of your system.
6. Enter the data acquisition parameters in the appropriate boxes located to the right of the displayed
spectrum. The values for Scans to Average and Smoothing Size must be the same for your
reference, dark and irradiance scans. You may use a different integration period for your
reference scan, but you must use the same integration period for your dark and irradiance scans.

Calibration
Performing Calibration
►Procedure
Follow the instructions below to calibrate a spectrometer using the HL-2000-CAL:
1. Click on the Spectrometer menu and select Calibrate, then select the channel to calibrate. A
dialog box opens with the message “Verify lamp was ON for at least 15 minutes for a
REFERENCE scan.”
2. Ensure that nothing is blocking the light path going to your spectrometer. Your setup
(spectrometer, fiber, and sampling optics) used to obtain a reference should be identical to your
setup for measuring your sample. Taking a reference spectrum is required before the software can
calculate absolute irradiance measurements.
3. Click the OK button. Another dialog box opens with the message “Block light path to
spectrometer for a DARK scan.”
4. Completely block the light path to your spectrometer by inserting an opaque object into the
lamp’s filter slot (if possible, do not turn off the light source). Taking a dark spectrum is required
before the software can calculate absolute irradiance measurements.
5. Click the OK button. The spectral response of your system is now calibrated. If you selected
Display calibration info when calculating in the Configure Spectrometer dialog box, you will
now see the results of the calibration procedure. The top left graph represents the linear 15th order
polynomial regression. The top right graph represents the dark scan. The bottom graph is the
calibration curve representing the spectral response of the process.
The calibration procedure is saved in a file named CHO.CAL for calibrating the master spectrometer
channel, CH1.CAL for calibrating the first slave spectrometer channel, and so on.
