Lens Holder

• This is a flange mounted lens holder assembly for PLD.
  
  Components
• Lens: 2" dia (or 50mm) S1 UV grade plano- convex lens with a focal length of 300mm is used to focus (image) the beam on to the target to get the required energy density.
• X, Y, Z assembly: The lens can be moved in X & Y and Z directions by the knobs provided.
• Flange: this flange mates to the laser port of the chamber and also allows positioning of a S1 UV Grade fused silica window (2" or 50mm dia).
• This allows the lens holder to be attached to the chamber thus freeing up space on the table.
• Fused silica disc: 2" dia (50mm) S1 UV grade fused silica window for allowing UV laser beam to pass into the vacuum side of the chamber.
• This disc is O ring sealed on the mounting flange.
