These 20 W xenon flash lamps employ a metal can package to achieve high output.
An MgF2 window type that emits a spectrum of light from 160 nm to 7500 nm is also available for a wide range of applications including industrial inspections, quantitative measurements, and chemical analysis. A high-output model with a built-in reflector is also provided that enables 1.5 times higher output.

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: At 20 W operation (main discharge voltage: 1000 V, main discharge capacitance: 1.0 μF, repetition rate: 40 Hz)
*4: 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 20 W (0.5 J to 0.02 J).
*5: See options for information on trigger sockets.

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.
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 operation.
