ULTRA-FAST PHOTODETECTOR BIPLANAR PHOTOTUBES R12290U SERIES, R1328U SERIES Biplanar phototubes are high-speed photodetectors capable of measuring waveforms of ultrashort optical pulses. Hamamatsu provides various types of biplanar photocathodes with different photocathodes to cover a wide range of applications spanning the vacuum UV to the infrared region. IR12290U series The R12290U series have a large sensitive area and fast time response, such as 270 ps rise time and 100 ps fall time. IR12290U-55 (For excimer laser measurements) The R12290U-55 was developed to directly measure high energy light such as from excimer lasers. Compared to conventional thermal conversion type detectors and semiconductor sensors the R12290U-55 offers fast time response and stable operation even when measuring high energy light. IR1328U series The R1328U series have very fast time response, such as 60 ps rise time and 90 ps fall time and excellent impedance matching. These characteristics make it possible to reproduce precise waveform of light pulses with extremely less ringing.
