Test the Focus Block for Freedom of Motion
Test the freedom of motion of the sliding focus block,
making sure that there is no significant stiffness,
binding, or lateral play at any point throughout the full
range of motion of the focus block (see Figure 52 ). If
necessary, loosen the three M3x12 hex, socket ‐ head
cap screws securing the guide block to the focus block,
and the two M3x16 hex, socket ‐ head cap screws that
tension the guide block, and readjust per the above
procedure until the resulting motion of the sliding focus
block is smooth, unrestricted, and without lateral play.
