1Introduction
Thank you for purchasing the Avantes AvaLight-D(H)-S. This light source will provide outstanding
performance. To get the best of its performance it perfectly matches all Avantes AvaSpec
spectrometers.
The AvaLight-D(H)-S provides more power than the AvaLight-DHc. The AvaLight-DH-S is Avantes most
powerful deuterium halogen light source. The AvaLight-D(H)-S is a combined deuterium and halogen
light source, capable of transmitting light in the UV/VIS/NIR-range.
The AvaLight-D-S is a deuterium light source only, making it a great option for measurements in the
UV range, 190-400 nm. The AvaLight-D-S-DUV version starts even lower at 175 nm, for your deep-UV
experiments. This version also offers twice the intensity at 200 nm.
The output of the AvaLight-DH-S is optimized for fibers or bundles upto 600 micrometers. For larger
fibers the focal point is manually adjustable to optimize the light coupling into your fiber.
The AvaLight-D(H)-S features an integrated TTL-shutter and filter holder for filters of up to
50x50x5.0 mm.
The AvaLight-D(H)-S is a risk group 3 product for the actinic UV range of the EN-IEC 62471 Photo
biological Safety Assessment.
Therefore additional measures are required for the AvaLight-D(H)-S.
Warning:
This lamp produces ultraviolet radiation, which are harmful to the eyes and skin. Avoid eye and
skin exposure to unshielded product.
DO NOT LOOK INTO THE LIGHT BEAM. THIS CAN CAUSE PERMANENT EYE DAMAGE –
WEAR PROTECTIVE EYE WEAR –USE THE SUPPLIED SAFETY GOGGLES.

2.2 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 “4.3 Trouble Shooting”. Switch to OFF to reset the Error LED.
Switching the Deuterium switch to upwards to OFF the Deuterium lamp switches off.

2.5 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, contact Avantes Technical Support.
The 2 Fuses are 1A slow blowing Fuses.
Disconnect power before opening housing or replace Fuse.
The installation category for this equipment is Class 2.

2.6 Halogen light power adjustment
The halogen light, that is focused through the Deuterium Lamp 0,5 mm aperture, can be regulated
in the optical power to match the Deuterium output. In order to obtain a more “ balanced”
spectrum, the multi-turn potentiometer in the backside of the light source can be turned to
regulate the halogen power.
2.7 I/O connector
For automatic shutter control to be controlled by software it is needed to connect an AvaSpec
spectrometer to the AvaLight-D(H)-S with the interface cable IC-DB26-2. Now it is possible to
control the shutter by software (AvaSoft).
The signals on the I/O connector are described below.

3Replacement of Deuterium or Halogen Lamp
Warning:
Make sure the Deuterium Lamp is switched OFF before disconnecting the power cord.
Before re-connecting the power cord, make sure that the power switch, the Deuterium lamp and
the Halogen lamp switch are switched off.
Warning:
During operation the lamp envelope reaches a temperature of approx. 250°C. Should you intend to
change the lamp please wait for at least 20 minutes for cooling before touching the lamp. The lamp
envelope (quartz glass) should not be touched with bare fingers, otherwise lifetime will be severely
reduced.
Please follow these instructions for the bulb replacement:
1. Switch off the light source and disconnect the unit from the mains power supply.
2. Remove both side covers by unclicking.
3. Remove the 4 screws securing the top cover by using a torx screwdriver to remove the top
cover.
4. Disconnect the deuterium power connector.
5. Dismount the front panel by unscrewing the 4 front screws.
6. Carefully slide out the front panel until the green connector is visible and disconnect the
connector of the switches.
7. Turn the light source upside down and carefully slide out the front panel.
