  6. Shelves This picture for 2nd pillars BEAM IS TILTED, use shelves with identical thickness => No up-down symmetry in choice of holes for 2nd & 3rd station, Upper raw for 2nd station, Lower raw for 3rd station. 6

  7. Shelves on 1st pillar Use identical, short shelves => up-down symmetry, lines only in outside raw. Shelves are adjustable in x and y by +/- 10mm 7

  8. Fixing shelf in the middle bottom vs OT2 or OT3 Lines lengthened by reversing mask holder and lens holder C – to see full 9*9 segment on any mask D – to increase depth of focus CCD adjustable in z with range 40 Lens fixed 200 OT 5th C-Frame OT 6th C-Frame IT 15+e 21 (C,D) 28 +5 D Z +5 C b line of sight in IT a 0 A (A,B) 10 0 B mask 43 Z 100 120 shelf 14 -3025 -2987 adjustable in x & y 115 level of table surface -3140= -6300+2400+760 153 10 75 8 220 190/220

  11. Tool for adjustingshelftoC-frame y x C-frame stop mechanism ON • This toolhelps: • make runners on shelf perpendicular to one C-frame • (in x-z plane and in y-z plane) • 2) adjust (in x and in y)shelf to hole in one C-frame |(2ndC-frame)-(far end of 1st new middle shelf)|-5= =501500 y First install cylinder z Then adjust shelf versus cylinder for every shelf on nearest C-frame in hole without mask holder side view Pillar (on sides) front view 11
