Andor ixon emccd depth of field.

Hi, 

First of all, I do not know if this is the correct place to ask this question. 

I am using Andor ixon 897 EMCCD camera with a regular lens from Edmund Optics. I want to calculate the depth of field (DoF) of this design.  I have found some depth of field (DOF)  calculators on the internet for specific cameras on the market. However, none of them provides information about the camera I use. Do any of you know how to deal with this problem? Any help would be appreciated. 

Thank you in advance.
