Light Source Options
Continuous wavelength lamps for steady-state measurements, the excitation rage is typically 230 nm to 1000 nm. Ozone generating lamps may be used to increase the lower range to 180 nm.
Microsecond Flash Lamp
Pulsed xenon microsecond flashlamps producing short microsecond pulses for phosphorescence decay measurements. The excitation range is typically 230 nm to 1000 nm.
Ultrafast Nanosecond Flash Lamp
Ultrafast nanosecond flashlamp for time-resolved fluorescence studies with decays of 100 ps – 50 us. The excitation range is gas depedent.
Picosecond Pulsed Diode Lasers and LEDs
We manufacture a range of picosecond pulsed laser diodes (EPL Series) and LEDs (EPLED Series) for Time Correlated Single Photon Counting (TCSPC) measurements. Diodes are available over the UV-VIS spectrum starting at 250 nm and are pre-set with a range of repetition frequencies. The driver electronics are built into the light sources, eliminating the need for additional driver boxes and feature true « plug-and-play » usability.
Continuous Wave (CW) Lasers
Continuous wave lasers for use with the FLS980 Fluorescence Spectrometer and the FS5 Spectrofluorometer. Some CW laser sources may also be pulsed by the spectrometer to allow, for example, upconversion decays with 808 nm and 980 nm excitation to be measured.
Vacuum Ultra-Violet (VUV) Light Sources
Vacuum Ultra-Violet (VUV) radiation is used to describe the spectrum below 190 nm, where few light sources readily emit and the atmosphere absorbs most of the wavelengths. Single wavelength and broad VUV spectrum options are available.
