Setting the TSA Microscope
The split-field switch must be set to the middle
position for the M604 microscope and the lever for
the IR camera opening must be in the IR position.
The left/right camera frame or the split field can be
set in the SETTINGS MENU (see section 3.2.4).
Microscope Lighting
Connect the microscope optical fiber to the IR light
source (lighting 3+4) in order to switch the lighting to
INFRARED MICROSCOPE in the display.
Set the brightness using the left/right potentiometers
on the left front plate.
Make separate lighting settings for right/left using
the right/left aperture diaphragms on the
microscope.
Focusing the Mask Level
Coarse focusing is possible using the TSA Z motion
located behind the TSA microscope.
Fine focusing is separately set on the M604
microscope. To do so, use the OBJECTIVE FOCUS
FINE MANUAL knob on the microscope.

For fine lens adjustment, use the OBJECTIVE
FOCUS FINE MANUAL knob on the microscope.
Adjustment (menu in the SUBSTRATE ADJUST-
MENT display)
Use the X, Y and theta micrometer screws on the
adjusting table for this. Adjust the substrate
adjusting crosses so that they are central-

Never adjust the substrate if the mask
and substrate are in contact! Doing so
will damage the mask and substrate.
Checking the Adjustment
