VPLED SERIES Adjustable Pulse Width UV & VIS LEDs The VPLED series of LEDs provide variable width pulses from ns to ms, as well as CW operation with powers in the mW range. They are optimised for long photoluminescence lifetime measurements using the Multi-Channel Scaling (MCS) detection method. The width of the excitation pulses is easily controlled from the VPLED allowing quick optimisation of the measurement conditions. The VPLED diodes are compact, maintenance free, and user-friendly. Although they are designed to match Edinburgh Instruments spectrometers, they can be incorporated into any experiment thanks to their external trigger capability. KEY FEATURES Optimised for MCS 14 Pre-set pulse widths from 50 ns to 1 ms External trigger capability Adjust pulse width and repetition rate with input trigger pulse Operation in CW mode Spectrally purified output Compact plug-and-play design Extremely low RF radiation
