R7400U-01

The R7400U-01 is designed as a subminiature photomultiplier tube with a 16 mm diameter and 12 mm seated length. A precision engineered 8-stage electron multiplier (composed of metal channel dynodes) is incorporated in the TO-8 package to produce a noise free gain of 700,000 times (R7400U).

The R7400U-01 has three features. The first one is world's smallest photomultiplier tubes assembled. (1/7th of the Hamamatsu R647). the necessary components are built into a TO-8 package while retaining full photomultiplier tube performance to create a new generation of photosensors. The second one is specially selected on account of low noise and high gain. For use in photon counting applications. The third one is the lens window type doubles the effective input area to 12 mm in diameter. That are all the main features.

Some general specifications of R7400U-01 have been concluded into several points as follow. The first one is about its minimum effective area which would be 8mm. The second one is about its dynode which would metal channel for structure and 8 stages. The third one is about its weight which would be approx 5.3g without lens and would be approx 6.3g with lens. The fourth one is about its operating ambient temperature and storage temperature range which would be from -80°C to +50°C without lens and would be from -30°C to +50°C with lens.

Also some characteristics about R7400U-01. The first one is about its spectral response which would be from 300nm to 850nm for the range and would be 400nm for the peak wave length. The second one is about its anode to cathode voltage which would be 1000V. The third one is about its average anode current which would be 0.1mA. The fourth one is about its cathode luminous which would be min 80uA/lm and typ 150uA/lm. And so on. For more information please contact us.
