Lens Coating
FlexiCoat Eyeglass / Eyewear Lens Coating System


The FlexiCoat Lens Coating System is an ultrasonic coating system that is ideal for applying functional and aesthetic lens coatings onto eyeglass or other lenses. The FlexiCoat System is an inline programmable 3-axis small footprint automated coating system with fully automated control of process parameters, program recipe storage, and many optional features, including conveyor.

The FlexiCoat is designed for applying Anti-fingerprint, Hard Coat or Scratch Resistant Coating (SRC), Anti-glare, Anti-fog, Anti-smudge, UV Blocker, tint (electrochromic), and photoresist onto eyeglass (including bifocals) and sunglass lenses with highly accurate repeatability and uniformity. Ultrasonic spray systems are well known for their precise thin film coatings and minimal overspray of expensive solutions. The FlexiCoat system is a full coating solution, replacing traditional coating techniques, such as dipping and spin coating, to reduce waste and minimize overspray. The FlexiCoat has the flexibility to develop a process as an R&D system and then be utilized at full potential for production volume coatings. The FlexiCoat is a quicker, inexpensive alternative or replacement to CVD machines, with proven expertise coating various types of lenses.

Lens Coating Ultrasonic Nozzle

The FlexiCoat system is fully integrated with Sono-Tek’s patented Vortex Ultrasonic Nozzle, which uses low velocity rotational air to direct the atomized spray onto targeted areas, providing superior uniform thin films with little overspray.

Examples of Lenses Coated:

  • Polycarbonate (lightweight durable plastic)
  • CR-39 Plastic (affordable, good optical clarity)
  • Trivex (impact resistant, thin, lightweight, excellent optics)
  • Hi-Index Plastic (thinnest material available, lightweight)
  • Glass (excellent optics, the most scratch resistant lens)
  • Polarized

Additional products that benefit from Sono-Tek’s ultrasonic spray lens coating technology:

  • Contact lenses
  • Optic lenses
  • Microscope lenses
  • Telescope lenses
  • Binocular lenses
  • Camera lenses
