SpletDeltaDiodes 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 50ps can be generated at repetition rates up to 100MHz. The DeltaDiode is perfect for applications such as: TCSPC excitation source. Fluorescence Lifetime Imaging (FLIM) Splet12. apr. 2024 · Consequently, the signal is generated only during a brief window of time, comparable to the length of the laser pulses. At such short time delays, pulses overlap, and light–matter interactions do not need to follow the time-ordering of the pulses. These out-of-sequence interactions can then lead to false signals. 35 35. D.
