These lamp modules integrate a 20 W xenon flash lamp with a power supply and trigger socket and are designed to extract maximum performance from the lamp. These will prove ideal for a wide variety of applications including those requiring a high flash repetition rate or high lamp input energy. With the electrodes positioned precisely, there is no need for troublesome optical axis alignment which is required sometimes during installation or wiring tasks.

*1: Internal: Adjustable with a trimmer
*2: External: Variable with control voltage from 1.9 V to 4.76 V
*3: 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
*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 (0.32 J to 0.02 J).
*5: External trigger only, synchronized at rising edge
*6: Cooling is necessary if the housing temperature exceeds 45 °C during operation.
