DeltaDiode™ Light Sources

The world's first 100MHz picosecond diode source with true plug-and-play interchangeable heads and USB interface!

DeltaDiode sources utilize laser diode and LED technology to generate short optical pulses over a very wide range of repetition rates and wavelengths. Optical pulses as short as 40 ps can be generated at repetition rates up to 100MHz. State of the art features such as hot-swap heads, USB control and full software integration mean the DeltaDiode delivers the highest level of performance in the most user-friendly package available today.

All DeltaDiode sources are controlled with a DeltaDiode driver interface.
DeltaDiode heads are switched using a single connection, with optimized settings stored in each head to enable the DeltaDiode software to "know" which head is connected.

Each DeltaDiode is designed to be used at a specific wavelength and has a pulse width of 40 to 1.5 ns (diode dependent). DeltaDiode sources can be selected from 250 to 830 nm for use with the DeltaPro.

SpectraLED Light Sources

SpectraLED Light SourcesThe SpectraLED is a novel light source designed specifically for the measurement of phosphorescence lifetimes. These sources are based on LED technology and the illumination wavelengths range from the UV to the NIR.

The addition of a SpectraLED source to the DeltaPro TCSPC system enables phosphorimeter capability and the measurement of luminescence lifetimes ranging from picoseconds to seconds in one compact system.

The SpectraLED is a modern approach to measuring longer lived luminescence decays. Traditionally, phosphorescence lifetime measurements are excited using a xenon flash lamp. Xenon lamps are broadband sources and offer complete wavelength coverage from the deep UV to the NIR region. For applications where continuous wavelength tunability is not required, SpectraLED sources are a convenient alternative with the following advantages:

SpectraLED Benefits

  • Operation at higher repetition rates not limited by capacitor charging times
  • Software control of pulse duration and repetition rate to optimally excite the sample under investigation
  • No afterglow, permitting easier interpretation of lifetimes shorter than 100 µs
  • Silent operation

Each SpectraLED is designed to be used for a specific wavelength range and has a variable pulse width from 100 ns to milliseconds, which is controlled by the DeltaPro acquisition software. SpectraLED’s can be selected from 265 to 835 nm for use with the DeltaPro and operate at repetition rates from 0.1 to 3 KHz depending on the measurement range.

SpectraLED sources do not require a special driver. They are software driven directly from the DeltaHub TCSPC interface.
