Introduction The D 2 H is a combined deuterium and halogen light source for UV/VIS and NIR applications. This light source is ideally suited to work with WPI s spectrometer modules and sample cells. It supplies a continuous spectrum in the UV, VIS and NIR range. The D 2 H is equipped with an integrated electrical shutter, which can be controlled by a switch or a TTL signal. Two models are available: the D 2 H covering a spectral range of 215 nm to 1700 nm, and the D 2 H-2 covering a spectral range of 190 nm to 1700 nm for deep UV applications. 3 1 5 11 12 4 10 Fig. 1 Front panel 7 6 2 8 9 Fig. 2 Rear panel. WORLD PRECISION INSTRUMENTS 2

Instrument Description Front Panel (Fig.1) (1) Power On Light (2) Mechanical Protector/SMA- Fiber-optic Connector The mechanical protector is a safety aide to prevent the user from unintentionally looking directly into the fi ber-optic connector. The connector is for use only with SMA fi ber-optic connectors. (3) Deuterium Start/Stop By pressing the button (3), the Deuterium lamp will preheat. After a warmup time of 20 sec. the Deuterium lamp will ignite automatically. By pressing the button (3) again, the Deuterium lamp switches off. (4) Two Color-LED Indicator for the Deuterium Lamp After successful ignition of the Deuterium lamp, the Two-Color-LED (4) lights up green and indicates that the Deuterium lamp is in operation. Should the Deuterium lamp not ignite, the Two Color-LED (4) lights up red. This indicates a malfunction of the lamp. (5) Tungsten (Halogen) Start/Stop By pressing the button (5), the tungsten (halogen) lamp switches on. By pressing the button (5) again, the tungsten (halogen) lamp switches off. (6) LED Indicator for the Tungsten (Halogen) Lamp When lit, the LED (6) indicates the lamp is in operating mode. (7) 3-Way Toggle Switch Set-up With the toggle switch (7) to the right, the TTL mode is active, i.e. the shutter will be controlled by the computer. In the middle position, the shutter is closed. With switch to the left, the shutter is open. WORLD PRECISION INSTRUMENTS 3

Rear Panel (Fig. 2) (8) Power Switch ON/OFF When the power switch is turned ON, power is supplied to the unit. The unit automatically switches to the basic operating mode. The LED (1) indicator is lighted up at this time. (9) Input Terminal for Power Cord (10) Fuse Input voltages AC 230...240V, 50/60 Hz (Version EUROPE) Input voltages AC 110...115V, 50/60 Hz (Version USA) This compartment contains the fuse to protect the unit against overload. (11) Cooling Fan (12) TTL Connection Cable connection permits external control of the lamp shutter (HIGH=OPEN, LOW=CLOSED, TTL input max. 5 Hz).

Parts List: 1 - D 2 H or D 2 H-2 Deuterium-Halogen light source 1 - Power cord 1 - This manual 1 - UV Goggles Unpacking Warning: In case of damage DO NOT USE THIS INSTRUMENT! Upon receipt of this instrument, make a thorough inspection of the contents and check for possible damage. Missing cartons or obvious damage to cartons should be noted on the delivery receipt before signing. Concealed loss or damage should be reported at once to the carrier and an inspection requested. Please read the section entitled Claims and Returns on the Warranty page of this manual. Unpack your new power supply / deuterium lamp assembly carefully. Although the deuterium lamp is rigidly mounted, dropping this instrument can cause permanent damage. Returns: Do not return any goods to WPI without obtaining prior approval and instructions from our Service Department. Goods returned (unauthorized) by collect freight may be refused. If a return shipment is necessary, use the original container. If the original container is not available, use a suitable substitute that is rigid and of adequate size. Wrap the instrument in paper or plastic surrounded with at least 100 mm (four inches) of shock absorbing material. Please read the section entitled Claims and Returns on the Warranty page of this manual. WORLD PRECISION INSTRUMENTS 5

Operating Instructions WARNING: This lamp produces ultraviolet radiation which can be harmful to the eyes. DO NOT LOOK INTO THE LIGHT BEAM. THIS CAN CAUSE PERMANENT EYE DAMAGE WEAR PROTECTIVE EYE WEAR. This unit is supplied with a mechanical safety device do not remove this safety device! Operating Conditions CAUTION: The unit must work in a horizontal position. Use this instrument in a clean laboratory environment. Moisture: The unit is designed for operation only in rooms with average or below average humidity. Ventilation: The unit should be situated so that its location or position does not interfere with its proper ventilation. Do not obstruct cooling fan openings. Heat: The unit should be situated away from radiators, ovens or other heat sources. Power sources: The unit should be connected to a power supply only of the type described in the operating instructions or as marked on the unit. Object and liquid entry: Care should be taken that objects do not fall, or liquids spill, into the instrument through any of its openings. 1. Power on After connecting the power supply to line voltage, turn on the power switch (8). The LED (1) indicates power on status. 2. Connect the fi ber optic cable connector to the D 2 H unit (2) (Fig. 3). WARNING: Do NOT look into the fi ber-optic connector. This lamp produces ultra violet radiation, which can be harmful to the eyes. Connect your fiber-optic cable first before starting the deuterium lamp (see side view of unit Fig. 3). Avoid direct radiation of skin and eyes at the fiber output end. 3. TTL 3-way toggle switch (7) WORLD PRECISION INSTRUMENTS 6

Fig. 3 Connecting the fiber optic cable. For automatic operation, connect your TTL control cable to the DB15 connector (cable not provided). See (12) on page 4 for details. If assistance is needed in identifying an appropriate cable, please contact Technical Support at WPI. With the toggle switch (7) to the right, the TTL mode is active, i.e. the shutter will be controlled by the computer. In the middle position, the shutter is closed. With switch to the left, the shutter is open. 4. Turn on the deuterium lamp By pressing the button (3), the deuterium lamp will preheat. After a warm-up time of 20 seconds, the deuterium lamp will ignite automatically. After successful ignition, the Two-Color-LED (4) lights up green and indicates that the deuterium lamp is in operation. Should the deuterium lamp not ignite, the Two-Color-LED (4) lights up red. This indicates a malfunction of the lamp. (See Troubleshooting). Press the button (3) again to reset the red LED. The deuterium lamp can be switched off by pressing the button again. 5. Deuterium lamp warm-up The Deuterium-Lamp typically needs 30 minutes to reach a thermal equilibrium. During this time the intensity of the UV-output varies. If applications require extreme intensity stability, the lamp should be warmed-up for an additional 15-30 min. After that time, the lamp will reach the specifi ed drift values. 6. Turn on the tungsten (halogen) lamp WORLD PRECISION INSTRUMENTS 7

By pressing the button (5) the tungsten (halogen) lamp is switched on. The LED (6) lights up and indicates that the halogen lamp is in operation. Should the LED (6) not light up, this indicates a malfunction of the internal power supply. (See Troubleshooting). The halogen lamp can be switched off by pressing the tungsten (halogen) button (5). 7. Tungsten (halogen) lamp warm-up The halogen lamp needs 5 to 10 minutes to reach a thermal equilibrium. During this time the intensity of the output varies. If applications require extreme intensity stability, the lamp should be warmed-up for an additional 15 min. After that time, the lamp will reach the specifi ed drift values. WORLD PRECISION INSTRUMENTS 8

Instrument Maintenance Replacement of deuterium lamp Warning: Disconnect the unit from mains connections (9)! Warning: Connection of the power cord to the deuterium lamp MUST only be done when the power switch (8) is turned OFF. As the output of the power supply is not galvanically separated from the line voltage, the connecting lead for the Deuterium lamp can carry a voltage > 42 V when the power switch is turned ON. 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 the lamp to cool before touching it. The lamp envelope (quartz glass) should not be touched with bare fi ngers, as this will decrease the lifetime of the lamp. Warning: Use only the originally supplied deuterium lamp connection plugs (17). 1. Open the unit: remove the six slotted screws (14) and open the casing cover (Fig. 4). Fig. 4 14 WORLD PRECISION INSTRUMENTS 9

2. Remove screws (15) using the tool (18) provided with the spare bulb (16) (Fig. 5). 3. Disconnect and remove the defective deuterium lamp module. 4. Put in the new deuterium lamp module and reconnect the lamp plug. 16 17 18 15 Fig. 5 WORLD PRECISION INSTRUMENTS 10
