Optical Bonding

The PVA Optical Bonding System is used to dispense and assemble optical devices in atmosphere without bubbles. It is an ideal solution for use with any optically clear acrylic or silicone.


The PVA710 Optical Bonding System offers a complete process including dam and seal dispensing and curing, fill dispensing and cover placement. Sample products include touch screen to LCD, cover glass to LCD, and more. This procedure improves transmittance, seals against contamination and increases overall ruggedness of the final product.

The system employs a robust gantry system featuring precision ball screw slides driven by brushless DC servo motors. Every axis of motion features optical encoder feedback for a truly closed-loop process. The cover glass trunnion provides an assembly means where the bonded surface is not contacted by the system.

Designed to accommodate a panel up to 17" at 16:9.

The PVA710 Optical Bonding System has many integrated features including:

  • Vision correction of X, Y and skew
  • Exclusive PathView® programming environment
  • PVA’s global service network
