  • Pulsed Lasers: How to Choose the Right Fast

    We hence need a detection system with 0.4 ns rise time sensitive at 355 nm. The Ophir FPD-VIS-300 is a Silicon photodetector sensitive from 320 to 1100 nm with a 0.3 ns rise time, corresponding to a bandwidth of 1.2 GHz. Using a 2 GHz oscilloscope and a 50 Ω , 4 GHz BNC cable, we calculate our total system response time to be:

  • Mantis shrimp–inspired organic photodetector

    2021-3-1 · The transmitted light at the output of OPV2 is then polarized by a LP (LP0), with a transmission axis parallel to the x axis. The light then traverses the first birefringent element FR1 and experiences successive phase retardations from a series of retarder layers r 1 to r N. This process results in spectrally dependent polarization rotations.
