1 Introduction

Thank you for purchasing the Avantes AvaLight-DH-CAL.

The AvaLight-DH-CAL is a calibrated light source for the UV/VIS/NIR spectral range (205 - 1099 nm).

This NIST traceable, calibrated light source is developed for use with all AvaSpec spectrometers to

be used in measuring absolute spectral intensity (in combination with a fiber-optic cable and an

irradiance measurement head).

The Avalight-DH-CAL is based on the standard AvaLight-DH-S light source. The standard SMA output

has been replaced by a diffuser of which the output is measured and defined in the calibration lamp

files (xxx.lmp) that come with it.

As a service the AvaLight-DH-CAL comes with a cosine corrector with SMA adapter. You can use this

or your own to calibrate your irradiance system. Note: This cosine corrector should not remain in

the lamp after calibration!

There are two calibration files, both valid for calibration with the cosine corrector. One calibration

file can be used for irradiance calibration over the full range (200 –1099 nm). In that case, both the

deuterium and halogen light need to be switched on during calibration. The other calibration file

can be used for irradiance calibration over the VIS/NIR range (350 –1095 nm). In that case, only the

halogen light needs to be switched. This provides a much smoother and stable output at the higher

wavelengths.

The calibration files can be imported to our software, AvaSoft 8, developed to make your

spectrometer system a spectroradiometer.

The AvaLight-DH-CAL-ISPxx is a special version of these calibrated light sources, meant to facilitate

the coupling of the AvaSphere-xx-IRRAD integrating spheres to the light source (xx = 30, 50 or 80).

Deuterium light

By switching the deuterium switch downwards to ON the deuterium lamp is preheated. After a

warm-up time of 10-20 sec. The deuterium lamp will ignite automatically.

After successful ignition the deuterium LED lights up green and indicates that the Deuterium lamp is

in operation. Should the deuterium lamp not ignite the deuterium LED lights up red. This indicates a

malfunction of the lamp. See section “Error! Reference source not found. Error! Reference

urce not found.”. Switch to OFF to reset the Error LED.

Switching the deuterium switch to upwards to OFF the deuterium lamp switches off.

Switching the halogen switch downwards to ON, the halogen lamp switches on. The halogen LED

indicates the operation mode.

Switching the halogen switch upwards to OFF, the halogen lamp switches off.

Power connector with double fuse and switch

The power connector for 100-240 VAC is located on the rear of the AvaLight-D(H)-S. Be careful to

use it with a designated power range only, please use the included power cord with the instrument.

For UK, US and Australian power cords, please contact Avantes Technical Support.

The 2 fuses are 1A slow blowing fuses.

Trouble shooting

Fault

Possible cause

Remedy

The light doesn’t turn on,

even though the clicking

sound is audible.

The front light switches

are ON before the main

power is switched on.

Put buttons for Deuterium and

Halogen in OFF position before

switching on the main power.

4 Technical support

4.1 Changing the light bulb

Since this light source is calibrated, the bulb exchange and recalibration can only be done in our

calibration lab.

Please note: the AvaLight-DH-CAL cannot be used as a light source for standard

reflection/absorption spectroscopy.

4.2 Getting help

If you have any questions, comments or requests concerning your AvaLight-XE-HP or the AvaSoft

software, please go to: http://www.avantes.com

In case you have any questions or need support, please send us an email via [email protected]

4.3 AvaSoft updates

To check for updates, you can choose “Check for Updates” from the Help menu or go to the

“Support” section on our website www.avantes.com.

4.4 AvaSoft and light soures

Using AvaSoft 8, one can calibrate the irradiance system consisting of a spectrometer, fiber and

irradiance measurement head (Cosine corrector or Integrating Sphere).

This is explained in the AvaSoft 8 Manual in the section “Perform Intensity Calibration”.

For more information on the control of light sources in AvaSoft, please refer to the AvaSoft 8

Manual, section Light Sources Control.
