H. C. Hamaker, Philips Res. Rept. 2, 55 (1947). Our Eq. (23) is his Eq. (27) except for the following differences: his σ0, β0, ρ1, ρ2, D are represented in our formula by σ, σ/τ, ρ0, ρ1, T, respectively. In addition, our formula is divided by the factor N0K(1 − e−μD). (his terminology) relative to his, making the result measure the fraction of generated light that reaches the photocathode, independent of x-ray flux absorption, etc. Finally, our formula contains a factor 2ρ2/(1 + ρ2) 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 ρ2 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.

σ and τ may be related to frequently used scattering parameters as follows: Let λa = absorption mean free path; λtr = transport mean free path. Then τ = (3/λaλtr)1/2 = (2τ/λa)1/2.
