After check a mistake has been found on the magnification. This seems to be the good calibration (feel free to cross check). The projection of the 2mm hex is attached
the calibration are :
NF_Refl: acA1920-40gm
pixel size (real): 5.86um
Magnification = 1.71
pixel size (image): 10um
image donne on input plan mirror M1 (accuracy about few mm)
NF_Trans: acA1920-40gm
pixel size (real): 5.86um
Magnification = 0.68
pixel size (image): 4um
image donne on output plan mirror M2 (accuracy about few mm)
The NF_inj was calibrated with the USB microscope (1.4um/pixel on microscope image). The 5th ring of the lens is about 1.89 mm in diameter.
NF_inj: acA1920-40gm
pixel size (real): 5.86um
Magnification = 1.54
pixel size (image): 9um

After installing cameras the actual calibration are :
NF_Refl: acA1920-40gm
pixel size (real): 5.86um
Magnification = [0.53,0.56]
pixel size (image): 3.22um
image donne on input plan mirror M1 (accuracy about few mm)
NF_Trans: acA1920-40gm
pixel size (real): 5.86um
Magnification = 1.32
pixel size (image): 7.73um
image donne on output plan mirror M2 (accuracy about few mm)
need to adjust the NF transmission as the Magnification is greater than 1.
