NOTE:
*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 1000 V, main discharge capacitance of 0.2 μF and a repetition rate of 100 Hz.
*4:See options for information on trigger sockets.

Trigger sockets E2418 , E2442

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.

Power supplies C13315 / C13316 series

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.
