pulslampen

Pulslampen are light sources designed to emit short, intense light pulses rather than continuous illumination. They are used in applications requiring high instantaneous brightness or precise timing for time-resolved measurements.

Two main categories are gas-discharge flash lamps and solid-state pulsed sources. Gas-discharge flash lamps (often xenon) operate by charging a capacitor and discharging it through a tube, producing a brief, bright flash with a broad spectrum. Solid-state pulsed sources include LED or laser-diode assemblies that emit short bursts with controllable duration and repetition rates. Some systems combine arrays of diodes or multiple lamps to shape the pulse or spectral output.

Typical pulse durations span microseconds to milliseconds, with peak brightness varying by design. Xenon flash tubes yield near daylight spectra, while LEDs provide narrowband or selectable wavelengths. Power supplies are high-voltage and require careful handling; cooling is sometimes necessary for repeated firing.

Pulslampen are widely used in photography and cinematography for stroboscopic effects, in scientific instrumentation for time-resolved spectroscopy or high-speed imaging, and in flow visualization techniques such as particle image velocimetry. Safety considerations include risks from intense light, UV or IR components, electrical hazards, and the need for shielding and eye protection.
