Laser Beam Aligning
Be careful not to shine the laser beam directly into the
person's eyes. Doing so may result in vision loss.
If the laser beam is not correctly positioned, there may be
distortion, causing the image to be enlarged or reduced, or
ghost shadows may occur and lower the image quality. Be
sure to align the Laser Beam properly.
1. Align the Vertical Beam with the center of the face (Mid-sagittal Line). (It is to
prevent the horizontal expansion of the image)
2. Align the Horizontal Beam in a straight line to the Frankfurt Line on the patient's
face. Use the Horizontal Beam button on the control panel to position it. Make
sure that the Horizontal Beam is aligned to the patient's face horizontally.
