Hamamatsu L4646 xenon flash lamp is a high-performance pulsed xenon light source manufactured by Hamamatsu Photonics. It delivers continuous spectrum covering ultraviolet, visible and infrared bands, widely used in UV-Vis spectrophotometers, gas analyzers, environmental monitoring equipment and optical measurement instruments.

This L4646 flash xenon lamp features instant ultra-high peak light output, low heat generation and short warm-up time. Compared with halogen lamps, it can generate about 1000 times instantaneous light intensity under only one-tenth input power. The unique electrode design ensures stable flash discharge, less electrode wear and long service life, up to hundreds of millions of flashes. The maximum repetition rate can reach 100Hz, ideal for precision photometric measurement.

When your spectroscopy instrument shows reduced light intensity, unstable spectral baseline or frequent flash failure, it is time for Hamamatsu L4646 xenon flash lamp replacement. Before lamp replacement, cut off instrument power completely and wait for full discharge of high-voltage circuit. Wear clean gloves, never touch the lamp window to avoid contamination which will affect spectral performance.

After installing the new Hamamatsu L4646 xenon flash lamp, perform spectrum calibration and light energy verification. We supply original and compatible Hamamatsu flash lamps including L4640, L4642, L4644, L4646, L4647 series.
