This Appendix describes how to measure laser power through the FH Flyer marking head using a
SYNRAD Power Wizard
®
power meter. Use this procedure to verify that Flyer is properly aligned to the la-
ser when it is mounted without using the SYNRAD designed L-bracket and Mounting Rail or to verify that
the laser is performing properly. Before beginning, read through the steps in the Setup, Input measurements,
and Output measurements sections so that you understand the sequence and the purpose of each step.
Setup
To prepare the marking head for power measurements, perform the following steps to ensure the optical
scanners are centered in the mark field:
1 Place a beam block on the marking surface in the field of the focusing lens. This prevents the beam
from traveling beyond the work area during power measurements.
2 Remove the Beam Enclosure Tube from between the L-bracket and the laser.
3 Power down the FH Flyer head and then connect your computer to the marking head via USB or
Ethernet.
4 On your computer, open the Digital Scope executable (DigScope.exe).
5 Power up the Flyer head. Cycling power to the head ensures that the optical scanner mirrors are
centered in the mark field.
Input measurements
Input power, measured just before the beam enters the marking head, provides a baseline of the actual
output power from the laser at a specific duty cycle (power level). In cases where additional optics such
as turning mirrors alter the beam path, we recommend taking power measurements before and after each
optic to verify that all components are properly aligned to the beam path.
Note: The steps below describe the use of a SYNRAD Power Wizard
®
PW-250 power meter to measure
laser output power. Refer to the Power Wizard
®
PW-250 Operation Instructions for detailed operat-
ing instructions. The Power Wizard PW-250 has an operational range of 1–250 W.
Caution
possible
equipment
damage
Take all power measurements on an unfocused beam. Never measure
a focused laser beam at the point of focus. Damage to the Power Wiz-
ard power meter will result.
