Sub-Nanosecond Pulsed LEDs - PLS 255 to 600

The PLS Series are the fastest miniature sub-nanosecond pulsed UV/blue/green/orange LED sources available. They combine short pulse widths (<600 ps FWHM) with high repetition rates (from single shot up to 40 MHz) in a compact and maintenance free set-up. They are interchangeable plug-in heads for the PDL 800-B, PDL 800-D, PDL 808 "Sepia" and PDL 828 "Sepia II" drivers and provide an ideal excitation source to replace flash lamps or Argon-ion lasers for fluorescence lifetime measurements. Their spectral and timing characteristics are also particularly suitable for biomedical applications, e.g. for the detection of labeled substances as well as naturally fluorescent amino acids like tryptophan or tyrosine. With peak powers up to 1.5 mW, a combination of interchangeable PLS Series heads satisfies the demand for a compact and affordable excitation source that covers a wide range of wavelengths.
