Converging the GREEN pattern onto the BLUE pattern
Next , align the GRE EN DMD in the vertical directions [ 4] and [5] and then proceed w ith t he horizontal direction [6].
1. To translate GREEN vertically in the Y + direction, turn both [4] and [5] cloc kwise. Turn screws in equal incr
ements.
2. To translate GR EEN vertically in t he Y - direction, turn both [ 4] an d [5] anti-clockwise. Turn screws in equal increments.
3. For clockwise rotations of GREEN, turning [5] anti-clockwise would generally suffice. If m uch rotation is required, [4] may also
be turned in the opposite direction. Slight corrections to Y may be required after rotation.
4. For anti-clockwise rotations of GREE N, turning [5] clockwise would generally suffice. If much rotation is required, [4] may also
be turned in the opposite direction. Slight corrections to Y may be required after rotation.
5. To translate GREE N horizontally in the X + direction, turn [6] clockwise.
6. To translate G R E EN horizontally in the X - direction, turn [6] a nti-clockwise.
