Filter based vacuum ultraviolet excitation accessory consisting of a deuterium lamp, power supply and magnesium fluoride window, providing excitation around 160 nm. Filter options select the excitation band. It is used for scintillator and phosphor work where excitation must be below the range of a normal xenon source.
| Parameter | Value |
|---|---|
| Lamp | Deuterium light source |
| Window material | Magnesium fluoride (MgF₂) |
| Excitation region | 160 nm, as described by Edinburgh Instruments |
| Configuration | Lamp with power supply; filters selected for the application |
The VUV source is an application-specific option. Confirm the required spectral band, filters, compatible spectrometer and beam-path configuration; no unverified lamp power or resolution is asserted. Checked 2026-09-29.

Vacuum ultraviolet excitation system giving continuous wavelength selection from 110 nm upwards, using a continuous wave deuterium source with a specially designed nanosecond flashlamp for lifetime measurement. The path from excitation monochromator to sample is evacuated through a light guide and the sample area is flushed, because air absorbs at these wavelengths.
Thyratron triggered all metal pulsed flashlamp filled with hydrogen or nitrogen, producing sub-nanosecond optical pulses for time resolved fluorescence. Because it is a lamp rather than a laser it gives continuous wavelength selection through the excitation monochromator, covering decays from 100 picoseconds to 50 microseconds.
Single wavelength continuous wave lasers supplied for applications such as semiconductor research, directed through a port in the spectrometer onto the sample. They are used where the excitation must be a monochromatic beam of steady intensity rather than a pulse.
