XPRESS EP Laser Marking Head
The XPRESS-series lasers have a unique, space-saving “L”
shaped footprint. Designed for easy maintenance, the galvo head
is mounted at a 90° angle to the laser rail. A heat exhaust fan is
located on the back side of the unit.
The laser marking head encloses the sealed laser resonator, the
beam expander, the turning mirror, the red light dry
run/positioning laser and the galvanometer assembly.

Marking Field Size
The size of the marking field is dependent on lens type.
See below.
Sealed Laser Resonator
The laser resonator is assembled and sealed in the clean room
environment to prevent optical contamination. The laser resonator
contains an electro-mechanical safety shutter. Under power, the
safety shutter allows 1064nm laser beam to pass through the
galvanometer steering mirrors. If the shutter is closed during
normal operation (or power is removed from the system via a
power off/stop condition) it will inhibit the 1064nm laser beam.
Visible Red Positioning Beam
The laser marking head produces a visible red diode that may be
viewed on the work surface without the need for protective safety
goggles. This provides a safe and convenient aid for laser setup
and part programming. Since the red beam is located
after
the
shutter, the positioning beam may be used with the shutter opened
or closed. Additionally, the visible red beam may be used with the
lasing beam during the marking cycle. Note that protective
eyewear should always be worn when the laser is in operation.
Flat Field Lens, Final Objective Lens, (F-Theta Lens)
The final object lens is key to the marking performance of the
system. This is the final coated optical lens that the beam will pass
through before it strikes the marking target. This lens is called a
flat field lens because when the beam is focused, the focus lies in a
plane perpendicular to the optical axis of the lens. To protect the
final objective lens from dust and debris, a clear protective cover
is inserted between the work area and the lens.
The following chart outlines the available lenses, the resulting
image field provided by the lens, and the working clearance (in
millimeters and inches).

Spot Size (line width)
In all cases, laser marked spot size is dependent on a variety of
factors including lens selection, focus, laser power, and the
material being marked. The following chart is provided for
