  • Handling and Cleaning Lens Savers® Windows

    Lens Savers® windows must be handled only while wearing finger cots or gloves made from latex or nitrile. When the windows remain in the bags in which they are shipped, care should be taken to pick the bags up only from the edges. Do not put fingers on the face of the crystal, even though […]

  • Selecting a Lens Savers® Window Mount or Adapter

    Lens Mounts for CO2 Laser Systems If you are using assist gas pressures in excess of 25 psig, you will need a special lens mount or adapter, or a modification of your lens mount, to deal with the high pressures. ICL will assist you in selecting one of its patent pending high pressure adapters or […]

  • Absorbance and Reflection

    Lens Savers® protective windows are polished optical crystal windows made from single crystal potassium chloride (KCl) and Sodium Chloride (NaCl). These optical materials absorb very little laser energy at 10.6 microns, which is the wavelength at which CO2 lasers operate. For YAG systems, the windows are made from a type of glass —BK-7— which absorbs […]

  • The Operating Environment

    Laser optics are subjected to a variety of conditions that cause performance degradation over time or which make it impossible to use the optics under certain conditions. These environmental factors include spatter, cleaning, pressure, moisture and heat. Variables that can affect optics life are the composition of the laser target, the composition of assist gases […]

  • Power Loss

    There are several reasons for power loss in a laser, but most of the losses are from Fresnel reflection of the laser beam off of the two (2) surfaces of the lens or window and from absorbance. Power loss in a laser system is a function of reflection losses and absorbance. As noted above, all […]
