The aiming and treatment beam (532nm) coincidence should be checked on a regular basis: the following
procedure should be carried out at least every
Required material:
Photographic paper (Kodak linagraph direct printer)
Alignment target / focusing bar
Checking procedure:
1. Attach a piece of photographic paper on the alignment target / focusing bar (See Figure 1 in the above section
2.2.3)
2. Switch ON the main switch located at the back of the OPTIMIS FUSION unit. The slit lamp is automatically
turned "ON" and illuminates the target paper.
3. Turn the keyswitch to the SLT position and wait for the OPTIMIS FUSION treatment screen to be displayed
(the laser is in STANDBY status by default).
4. Adjust the eyepieces to accommodate the user's eyes.
5. View the target through the binocular (with the magnification changer set to x16).
6. Adjust the slit lamp position so that the aiming beam forms only one clear, well defined spot on the paper
attached to the target (focal distance) and lock the slit lamp in this position
centered in the field of view and in the center of the illumination aperture. Lock the slit lamp in this position
(See Figure 2 in the above section 2.2.3)
WARNING
If the aiming beam is not centered: do not use the système and contact QUANTEL MEDICAL Service
Department or your local distributor.
7. Adjust:
- Low energy
8. Press the STANDBY/READY button on the control module to select READY status and fire the laser on the
target paper.
9. Inspect the burn mark through the binoculars to check that the aiming beam spot coincides with the burn
mark (See Figure 3 in the above section 2.2.3)
NOTE
Depending of the photographic type of paper used for the checkup: the burn mark might not clearly be
distinguished with minimum power in use. In this case, power may have to be increased step by step until
coincidence can clearly be checked.
WARNING
In case the aiming beam/treatment beams do not coincide: do not use the system on patients. Contact
QUANTEL MEDICAL Service Department or your local distributor.
