When you received the FARO LLP there should have been a small Kinetronics Lens Cleaning Cloth kit in one of the side pouches in the carrying case. To clean the lense of the LLP please use this cloth without liquid application. This is to clean the outside lenses of the LLP. If the mirror inside the Lase Line Probe appears to be dirty you will want to contact Customer Support at firstname.lastname@example.org and schedule a cleaning and certification.
If you do not have a Kinetronics Lens Cleaning Cloth kit, you can purchase them at any camera utility store or you may contact FARO Technologies and request one.
