Numerous components can then be coupled to the 8-mm-diameter smooth rods and adjus-
ted in the z -vertical axis to build up an optical assembly including a static filter or lens squar e 21
( Figure 6.11 ) or circular holder 22 ( Figure 6.12 ), kinematic mirror or lens holder 23 ( Figure 6.13 ),
static fiber-optic holder 24 ( Figure 6.14 ) , screen holder 25 ( Figure 6.15 ) and sample holder 26 ( Fig-
ure 6.16 ) . The filters in the square holders are fixed in position using M3 screws and nuts and
a filter bracket, while for the circular holder, a set screw is applied as shown in Figure 6.12 .
