Marking head
The purpose of the marking head is to position and focus the laser beam onto the marking surface. This
process begins as the laser’s output beam enters the head through an expansion telescope. After expan-
sion, the beam is collimated and then directed onto two lightweight X and Y mirrors mounted on separate
high-speed optical scanners. These mirrors position the beam and direct it out through a single-element
focusing lens onto the mark surface. This focusing design, where the beam is focused after the steering
optics, is called post-objective focus. The advantage of post-objective focus is that a flat-field lens can be
used to achieve final focus, providing excellent mark quality since the focused spot is located in the same
horizontal plane over the entire marking field.
WinMark Pro laser marking software sends vector data and laser power commands to FH Flyer through
a USB or Ethernet connection where the processor on Flyer’s control board converts vector data to
microvector commands. These microvector commands, as well as the corresponding laser power com-
mands, are sent to the Digital Signal Processor (DSP) on the control board. The DSP, which implements
the servo loop that controls the position of the optical scanners, generates the correct timing between
the microvector commands to insure the commanded marking speed and marking delays. The DSP also
generates laser power commands and routes them to laser control circuitry on the control board in order
to synchronize laser firing with movement of the optical scanners. This laser control circuitry generates a
fixed 5 kHz tickle signal that maintains plasma ionization in the laser tube when the laser is commanded
off and generates a variable Pulse Width Modulated (PWM) laser control signal that is user-adjustable (in
WinMark Pro v6) within a frequency range of 1–50 kHz when the laser is commanded to fire.
Note: FH Flyer’s operating system requires approximately 25–30 seconds to boot up. Repeatedly cycling
power during boot up may cause corruption of Flyer’s flash memory and operating system.
Beam expansion
Three distinct expansion ratios are available for FH Flyer marking heads. Depending upon the laser’s beam
diameter a 3X (48 Series and Firestar f100 lasers), 2.5X (Evolution lasers), or 5X (Firestar v-Series and
t-Series lasers) expander telescope may be installed. Figure 6 -1 shows the expander telescope location.
You can identify FH expanders by their anodized color-coding—2.5X expanders are silver (clear anodized
coat-ing over an aluminum housing), 3X expanders are black , and 5X expander telescopes are red.
In facilities where multiple laser types are used, remember to check that the expander ratio matches the
