Molding Glass Toroidal Lens

  • Realized toroidal lens, the mass production of which was difficult in the past, through precision molding processes.
  • Producing toroidal lens by molding tool, became possible mass production with small individual differences.
molding glass toroidal lens


  • beam formation
  • Aspherical toric lenses is applied for sensors (elliptical detection area)
  • laser beam printers, others


Overall Size less than 15mm
Center Thickness 2mm~15mm
