Customization / Measurement method | Xenon flash lamps

Xenon flash lamps are pulsed light sources that emit light with an instantaneously high peak output.
The emitted light is a continuous spectrum from the UV to the infrared region and is used for a wide range of applications including chemical analysis and imaging.
Hamamatsu provides high-quality, high-precision xenon flash lamps, as well as peripheral devices such as specially designed trigger sockets and power supplies to extract maximum performance from xenon flash lamps. Easy-to-use lamp modules integrated with those peripheral devices are also available.

Designing an optimal drive circuit is essential for obtaining maximum performance from a xenon flash lamp. Peripheral devices such as power supplies and trigger sockets designed specifically for xenon flash lamps are available, and also technical support for designing those circuits and devices can be provided. Any requests for custom products not listed in our catalog are welcome, so please feel free to consult us about your applications and operating conditions.

Measurement method

Xenon flash lamps are pulsed light sources and may cause large noise in the detected signal if using a measurement method for DC light sources. To avoid this, measurements must be made in synchronization with each flash of the lamp and a peak-hold circuit or sample-and-hold circuit. When using a camera or spectrometer, it is important to set the integration time so that the signal is acquired only at the timing of light emission.

● Setup example

A xenon flash lamp produces a light flash several microseconds after the trigger signal is input (delay time). Also, time fluctuations (jitter time) of a few hundred nanoseconds occur with each flash. This delay and jitter time must be taken into account in order to make accurate measurements.
