Chapter 2
Operation
Overview
The DH-mini Light Source includes both a deuterium and a halogen bulb for UV-VIS-NIR
measurements. There are two ways to control the DH-mini: using the push buttons on the front panel or
the TTL inputs on the rear panel. After power-on the Power LED will glow and the device will be in TTL
control mode which is highlighted by the yellow TTL/ Manual LED.
Operating Modes
To toggle between Manual Mode and TTL Mode you have to push the TTL/Manual button on the front
panel. The corresponding yellow LED next to the button toggles on and off with each push. A lit LED
indicates TTL Mode. If the LED is off, the device is in Manual Mode.
Manual mode –operates with the pushbuttons on the front panel
TTL mode –operates with the TTL inputs on the rear panel.

2: Operation
6000-10000-200-02-201506b
Manual Mode
In this mode you can switch the bulbs and the shutter via the corresponding push buttons.
Control
Action
Deuterium
Press button to turn Deuterium bulb on. The LED lights. Observe the warm-up time of 6
minutes to ensure that the light source has reached a stable operating state before taking
measurements.
Press button again to turn the Deuterium bulb off. The LED extinguishes.
Halogen
Press button to turn Halogen bulb on. The LED lights. Observe the warm-up time of 6
minutes to ensure that the light source has reached a stable operating state before taking
measurements.
Press button again to turn the Halogen bulb off. The LED extinguishes.
Shutter
Press button to open shutter. The LED lights.
Press button again to close the shutter. The LED extinguishes.
TTL/Manual
Press button to switch from Manual mode to TTL mode. The LED lights. See TTL Mode.
Press button again to switch from TTL mode to Manual mode. The LED extinguishes.
TTL Mode
The DH-mini always starts up in TTL mode. You can also switch to TTL mode by pressing the
TTL/Manual button (yellow LED is lit) if the light source is in Manual mode. The bulbs and the shutter
assume the state of the corresponding TTL signal when the light source is in TTL mode.
Note
If there are no signals connected to the logic ports o rear of the device, the device reads a
low signal (Deuterium bulb off, Halogen bulb off and shutter closed).

If you want to use OceanView to control the DH-mini via a spectrometer you can use the Strobe/Lamp
Enable check box to control the shutter. See Attaching to Ocean Optics Spectrometers for more pinout
information.
Change Intensity of Halogen Bulb
To change the intensity of the Halogen bulb, use trimmer screw on the left side of the device. Use a
flathead screwdriver to turn the screw clockwise to increase the intensity, counterclockwise to decrease it.
The full range can be set with approximately 30 screw rotations.

Spectral Output
The following graph shows spectral outputs of a DH-mini recorded with three spectrometers. All
spectrometers have measured irradiance spectra. The balance from the Deuterium spectrum (~200 –
400nm) to the Halogen spectrum (~400 –1600 nm) can be changed by varying the intensity of the
Halogen bulb (see Change Intensity of Halogen Bulb).

Appendix B
Bulb Replacement
Overview
If the lifetime of either the Deuterium bulb or the Halogen bulb is reached or if one bulb is broken you
can replace the bulbs. Both bulbs are arranged in one housing so the bulbs cannot be changed separately.
To order replacement bulbs for the DH-mini, see Spectral Output.
Replacing the Bulb
►Procedure
To replace the bulbs,
1. Remove all eight countersunk screws on each side of the light source housing with the provided
Hexagonal socket screw key SW 2.0.
2. Lift the housing off of the light source.

3. To remove the bulb, disconnect the cable at the rear side of the lamp first (1). Then use the
provided Hexagonal socket screw key SW 1.5 to loosen the stud screw (2).
4. Pull the bulb from the light source.
5. Insert a new bulb. Be careful to correctly align it with the connection holes on the PCB (3).
