4. 2) relative to his, which is the transmission factor of the phosphor-photocathode interface. The use of this factor may be open to question. If the dominant influence in 2 is reflection at the photocathode-vacuum interface, this factor should probably be omitted. Note that this factor equals unity when the cathode is nonreflecting, as was assumed in most of the results presented here. In any event, the relative MTF curve is not affected by this factor.
