Question question regarding PMT photocathode and quantum efficiency 

Forum: Processes Involving Optical Photons

From: Athreya Shankar <Athreya Shankar>

Hello all,

I wish to simulate a PMT photocathode for detection of photons. In PMT datasheets, the photocathode quantum effiency is specified taking into account the effect of the glass window on the transmission of photons. This is evident from the fact that for the same bialkali photocathode, the Quantum efficiency varies with the window material

In this case, is it appropriate to set this quantum efficiency (QE) to the photocathode surface at the back of the glass window, or does it not amount to accounting twice for the effect of the glass window? (once by placing the window physically before the photocathode, and once again by specifying the QE which already takes into account the effect of this window)

Thanks in advance,

Athreya
