PGx Portable Contact Angle meter helps in lens coating inspection

Lens coating inspection

Vision Labs is a member of the Specsavers Group supplying quality prescription lenses to Specsavers Opticians in the UK, Northern Ireland and the Netherlands. Vision Labs approached Henniker to help improve a quality/inspection task for their range of standard and super-hydrophobic lens coatings.

Using the PGx Portable Contact Angle instrument we were able to demonstrate accurate and repeatable contact angle measurements on a wide range of lens coatings. The PGx has now replaced a tedious and largely subjective inspection method, making life a whole lot easier for the inspection team!

The PGx is a fully automated Portable Contact Angle Meter that measures surface wetting and absorption in-situ on virtually any size or shape of surface.

With a footprint of only 90mm x 55mm and weighing just 400g, it is the smallest contact angle meter available, with features previously found only in larger laboratory instruments. The PGx enables direct surface testing of almost any 3D object without having to cut the sample to fit. Simply place the PGx Portable Contact Angle Meter on your sample or part and press a single button .

The PGx automatically delivers a precisely calibrated drop onto the surface and the built in camera captures a video sequence of the surface wetting at a rate of 80 frames per second. The results are displayed as a static contact angle or dynamic wetting as a function of time, providing detailed information about the liquid/substrate interaction in a truly portable instrument.
