System Specifications
Compliance............................ CDRH, CSA
Laser Type ............................. Q-switched Ytterbium fiber
Wavelength............................ 1060 nanometers (±10 nm)
CW Average Power .............. 20 watts
Expected Diode Lifetime ....... >50,000 hours
Long Term Output
Power Drift ......................... ± 5%
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 aiming beam may be used with the shutter opened or
closed. Additionally, the visible red beam may be used with the
lasing beam
Avg. Power Consumption...... < 500 watts
Input Power ........................... 95 to 250 VAC 50/60 Hz
Supply Voltage Fluctuation ... ± 10%, maximum; clean ground line
Oper. Temperature................. 18° to 35°C (65° to 95°F)
Recommended Temp. ............ 20° to 25°C (68° to 77°F)
Oper. Relative Humidity........ 10% to 85%, non-condensing
Laser Marking Head
The laser marking head includes the shutter assembly, visible red
aiming diode, circuit board, galvanometer assembly, and the flat-
field lens. The beam collimator and isolator (at the end of the fiber
optic cable) are enclosed within the laser marking head.

during the marking cycle. Note that protective
eyewear must always be worn when the laser is in operation.
Flat-Field Lens
The flat-field 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
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).
