Information about numerical aperture

Hi,
I'm using the DLP NIRscan Nano with its illumination module and the sample stuck to the glass in reflective mode.
But now, I would like to use it in transmittance mode without the illumination module.
To maximise the signal passing through the sample, I need to know what is the numerical aperture of the DLP without the illumination module.
Does someone know what this apperture is ? I searched in the DLP's documentation but I found nothing...
