xenon flash lamp

60 W xenon flash lamps

These are 60 W xenon flash lamps that deliver the highest output among our xenon flash lamps. Despite their high output, these lamps are highly stable. A built-in reflector type with an even higher output is also provided that boosts the output 1.5 times higher than that of other 60 W lamps.

*1: To ensure highly stable operation, 10 Hz or more repetition rate is recommended.
*2: Light output stability (at a repetition rate of 10 Hz or more)
     Light output stability (% CV) = light output standard deviation / average light output × 100
     Light output stability (% p-p) = (maximum light output – minimum light output) / average light output × 100
*3: Measured with a Hamamatsu Si photodiode S1336-8BQ. The life is defined as the time at which the light output at 190 nm to 1100 nm decreases to 50 % of the initial output level or the light output fluctuation exceeds the specified maximum value when the lamp is operated at a main discharge voltage of 975 V, main discharge capacitance of 2.1 μF and a repetition rate of 60 Hz.
*4: When the Maximum repetition rate is 15 W or more, cooling is necessary to keep the lamp bulb temperature lower than 150 °C. Use the E6611 cooling jacket available as an option.
*5:See options for information on trigger socket.
*6:See options for information on cooling jacket.

Trigger socket E6647

Hamamatsu provides trigger sockets specifically designed for xenon flash lamps. These trigger sockets are integrated with a high-voltage transformer, voltage-divider resistors, and capacitors in the same compact housing thus reducing the hassle of drawing up circuit and device designs.

Cooling jacket E6611

The E6611 is a cooling jacket specifically designed for 60 W xenon flash lamps. It helps keep the temperature of the xenon flash lamp and trigger socket at a constant level within the tolerance range to ensure highly stable operation.
* The cooling jacket must be used when the lamp is operated with an input of 15 W or more.

Main discharge capacitor (external connection) E7289-02

The E7289-02 is a main discharge capacitor (2 μF) intended to operate a 60 W xenon flash lamp with a maximum average lamp input (continuous) of 60 W. By just connecting to the dedicated power supply, the E7289-02 starts safe operation.

Power supply C14352

Hamamatsu provides power supplies specifically designed to bring out maximum performance of xenon flash lamps. These are switching power supplies with a built-in high-speed charging circuit and discharge stop circuit. Despite their compact size and large capacity, the power supplies ensure highly stable xenon flash lamp operations.
