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 de-
tectors 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.

NOTE: APulse width is less than 50 ns. BOutput current averaged over 1 second time interval. The whole photocathode is uniformly illuminated.
CMeasured with a tungsten lamp operated at 2856 K and a 1 MΩ load resistor. The light input is 0.05 lm.
DRise time refers to the time rising from 10 % to 90 % of the peak photocathode current when delta function light pulse enters the whole photocathode.
EFall time refers to the time falling from 90 % to 10 % of the peak photocathode current when delta function light pulse enters the whole photocathode.
