27.3.4.2 Optical Alignment of the lamp
What may be adjusted!!
The adjustments to the Y-axis and X-axis (balancing the light intensity) are
FACTORY PREADJUSTED
. Consequently, both ad-
justable screws are anchored by a lock screw and sealed with a warranty label (Destroying the label void the warranty).
ONLY
the Optical readjustment to the Z-axis may be done and is recommended after the lamp has operated for many run times. An
optical realignment of the lamp to the z-axis could compensate the decrease in light output.
