Number of photons through glass I am getting mixed information on the total photon count involved with light transmission through glass. I'm not looking for percentages and I don't have equipment to count photons.
For simplicity say you shine laser that produces 1000 photons per second through glass. I know that depending on the glass thickness the reflection from the front surface can range between 0 and 16% but that doesn't tell me the number of photons.
A side from photons absorbed in the glass (hopefully minimally) are there charts that show the actual photon counts:
(1) After going through the glass.
(2) Reflected back. 
Are there charts for different thicknesses of glass?
For example could a light source of 1000 photons per second transmits 656 photons, reflect 125 and refract or absorb the other 219? In short are all the photons accounted for? Thanks
 A: In the world of linear optics we assume that $T+R+A=1$, Transmitted, Reflected, Absorbed.  For optical glass absorptance is very low, so set $A=0$.
This leads us to the result described in the comments: $T=1-R$.  
I use this when doing quantum optics in the lab; in order to maximize transmission we use (a) fine optics that are designed for the wavelengths being used, (b) anti-reflection coatings, (c) the minimum number of passive optical elements required to get the job done.
In the end you will always lose some photons, but if the system works for large numbers of photons, it will also (most of the time) work for small numbers of photons.  This is because most passive optical devices can be modeled as unitary operators and there is (usually) no feedback into the laser cavity, so the experimental Hamiltonian isn't being perturbed.
Once you have your experiment setup and working properly you can test it with phase plates of various thickness, and report back if the quantum counting still agrees with the $T=1-R$ prediction.
