The distance does not actually matter, as this is the only laser available with acollimated beam. We recommend working from a distance of 1 to 3 inches withthe 6mm lens, so it is close enough for easy aiming yet far enough from the skin so that the handpiece does not visually obscure the target. Although thedistance doesn’t affect the energy being emitted at the suggested distance, the size of the aiming beam is truer to the spot size
When using the 2mm lens, the distance rods should slightly touch the skin without applying too much pressure on the patient’s skin. This is the best way to ensure that the appropriate energy is being delivered since the 2mm focus lens is distance dependent.
