Checking the Condition of the Handpiece
Some optics within the system are more susceptible to damage than others. After a long period of
use, certain optics need to be inspected and unless their condition is pristine, replaced. The first
optics to inspect are the handpiece lenses. Any dirt or discoloration in the coating surface will
affect the handpiece transmission and thus the overall efficiency of the laser.
WARNING: Never look directly into the handpiece while the laser is on, even when
wearing protective eyewear; serious eye injury can occur.
1. Turn off laser if laser is on.
2. Disconnect the fiber from handpiece. Remove the treatment tip if attached. Inspect the
window and replace if damaged.
3. Examine the condition of the handpiece lenses, by sighting down the barrel. A handpiece
in good working order provides a clear, unobstructed view through the lens. See
examples below.
Dirty Lenses, Unacceptable Clean Lenses, Good
4. If the handpiece lenses appear dirty, scratched, discolored, or pitted, then test the laser
with a good handpiece and repair or replace the damaged lenses.
5. If handpiece lenses are replaced, verify spot size. If necessary re-spot the actual spot size
of the handpiece in accordance with Cynosure’s recommended procedures for handpiece
repair.
Checking the Focus Lens
Additional optics that are susceptible to wear and optical damage are the focus lens, turning
mirror and the beam combiner. It is important when working with these optics that the parts stay
clean and free of oils and fingerprints. Follow the procedure for aligning the focusing lens as
described in the
Final Test and Calibration Procedure.
The fiber coupling transmission should be approximately 80% of resonator energy with new or
good quality optics.
