We no longer offer this product. If you want repair service or a custom modern equivalent, contact us.
This is a Hamamatsu R1328U-01 ultra-fast biplanar phototube. The R1328U-01 is equivalent to the R1328U-51 with regards to performance, the only difference being the HV connector which is MHV on this model and SHV on the R1328U-51. An N to BNC adapter for the output is included.
The R1328U series have a very fast time response and excellent impedance matching. These characteristics make it possible to precisely reproduce light waveforms with very little ringing.
