What is Ultrasonic Lens Coating?

The ultrasonic lens coating system is an ideal choice for coating functional and aesthetic lenses onto glasses or other lenses. The system is designed to apply anti fingerprint, hard coating or scratch resistant coating (SRC), anti glare, anti fog, anti fouling, UV blocking agents, coloring (electrochromic), and photoresist to glasses (including bifocal lenses) and sunglasses with high accuracy, repeatability, and uniformity. The ultrasonic coating system is known for its precise thin film coating and minimal expensive solution overspray, replacing traditional coating techniques such as impregnation and spin coating to reduce waste and minimize overspray.

 

 

Example of coated lenses:

 

Polycarbonate (lightweight and durable plastic)

CR-39 plastic (affordable, good optical transparency)

Trivex (impact resistant, thin, lightweight, excellent optical performance)

Hi Index plastic (thinnest material, lightweight)

Glass (excellent optical performance, the most scratch resistant lens)

polarization
