    Luxinar does not accept liability for any damage or injury howsoever caused or arising. 1.5. Maximum Permissible Exposure and Nominal Ocular Hazard Distance The Maximum Permissible Exposure (MPE) is the level of radiation to which, under normal circumstances, persons may be exposed without adverse effects.

  • Page 15: Decommissioning And Disposal

    and the general public are in many countries specified in national laws. These legally-binding national exposure limits might differ from the MPEs given in the tables below. The NOHD is the distance from the output aperture beyond which the beam irradiance or radiant exposure remains below the appropriate MPE.

    Refer to Chapter 8 for interfacing details. 2.6.5. Cooling system The OEM 45iX requires a temperature stabilised recirculating coolant circuit in order to operate correctly. The preferred coolant is deionised water or deionised water with anti-bacterial additive. See Appendix Important! To prevent condensation on optical surfaces, the coolant temperature must be maintained above the dew point.
