Xenon Arc Lamp Spectra

Their sun like emission spectrum and 5800 k color temperature make them a popular choice for solar simulation as well as absorption and fluorescence and source spectral scanning applications.

Xenon arc lamp spectra.

The xenon arc has the advantage of being spectrally closer to daylight than the incandescent source. Of light energy color temperature of 5600 kelvin. It produces a bright white light that closely mimics natural sunlight with applications in movie projectors in theaters in searchlights and for specialized uses in industry and research to simulate sunlight often for. Moisture is provided by a humidifier and direct spray and temperature is controlled by heaters.

Uxl spectral distribution is well balanced in the visible spectrum to resemble daylight. Glass filters around the xenon arc modify the light spectrum to simulate the appropriate end use conditions. A xenon arc lamp is a special type of gas discharge lamp. Xenon xe arc lamps have a relatively smooth emission curve in the uv to visible spectrums with characteristic wavelengths emitted from 750 1000 nm.

A weather ometer uses a xenon arc light source to provide a radiation spectrum that simulates natural sunlight. The lamp replacement is easy and precision system alignment is not required. The xenon lamp contains two electrodes enclosed in a glass bulb filled with xenon gas. Our xenon arc lamp based solar simulators provide the closest spectral match to solar spectra available from any artificial source.

Fast ignition and a stable arc are what ushio has achieved with the uxl lamp design. A xenon arc lamp is a highly specialized type of gas discharge lamp an electric light that produces light by passing electricity through ionized xenon gas at high pressure. Xenon arc exposure results historically the majority of xenon arc weathering and light stability testers have been designed with a lamp in the center of the chamber and a cylindrical specimen mounting rack which rotates the test specimens around the light source like a carousel.

1 flash pulse waveforms at different arc sizes. The high gas fill pressure provides high luminance and high luminous efficacy. Ushio s uxl series are high pressure short arc xenon discharge lamps. High voltage is applied to the electrodes which momentarily releases sparks to create light flash.

Xenon arc lamps produce light by passing electricity through ionized xenon gas at high pressure. It produces a bright white light that closely mimics natural sunlight which extends its applications into the film. The match is not exact but better than needed for many applications.
