Trigger Socket E6647

In order to operate a Xenon flash lamp, it is necessary to supply the prescribed high voltage between anode and cathode, and to trigger probes. To facilitate the above operation, the trigger socket consists of high voltage transformer and voltage divider resistors and capacitors chain to supply the appropriate pulse voltage to each electrode. As E6647 radiates heat from its metal parts during the operation due to the input energy, it is recommended to use a cooling fan to keep the surface temperature of the metal parts at less than 50 °C.

Power Supply C6096

C6096 has large capability to operate the lamp stable in spite of its compact dimensions. At 1 J/flash input energy becomes over 0.05 J, it is necessary to have an additional external capacitor E7289-01 (option).

Cooling Jacket E6611

This cooling jacket is exclusively designed for 60 W Xenon flash lamps will keep the temperature of the lamp and electric parts such as the trigger socket at less than maximum ratings and maintain at even temperature by a built-in cooling fan, and offers the stable operation of the lamp. It has to be used for the operation of more than 15 W input.

Light-Guides

Light-guides are effective to guide the output light into a place where does not allow to direct irradiation due to its construction or to plural places simultaneously. A short arc of 60 W Xenon flash lamps allows the light into the light-guides effectively. As the standard option, two types of light guide are available from us upon your application. Please refer to below table.The light-guides holder for the cooling jacket is also available from Hamamatsu. (The light-guides holder will be included for the combination order of the cooling jacket and the standard light-guides.)

External Main Discharge Capacitor E7289-01

The exclusive main discharge capacitor (2 µF) for 60 W (1 J/Flash, 60 Hz) inputs the operation of 60 W Xenon flash lamp series. It allows to operate safely by easy connection with a power supply.
