7. The objectives were the Mitutoyo MPlan APO long working distance infinity corrected objectives. The X2, X5 objectives were used here with the MT-40 tube lens (X1) refocusing on a C-mount CCD. Edmunds Scientific recommends in their catalog a C-mount tube length of 142. 5 mm.
8. 190-mm-thick YAG, with 4-mm-thick Ce doping purchased from St-Gobain Crystals and Detectors, 440-564-2251.
9. 500-mm-thick YAG:Ce single crystal, purchased from www.startechinst. com, model F20G YAG:Ce doped.
10. Note that YAG has a composition of Y3Al5O12 with a density of 4. 55 g/cm3. Thus the X-ray absorption length at 10 keV is 57. 1mm.
11. The two half lenses are housed in a stainless-steel pipe and sealed by two CF flanges each having a brazed in 0. 125-mm-thick Be window. The length of the unit is 403 mm. If one removes the unit from the beam, the air transmission factor is 0. 82.
