Aspheric Molded Cell Phone Lenses in Tray

​

• 4D (x, y, z, thickness) measurement of aspheric molded cell phone lenses in tray\

​

• Use 1mm chromatic confocal sensor (with z-stitching) to measure lens top and bottom surface simultaneously at 20 nm height resolution and 1 micron lateral sampling

​

• Use the surface topography and thickness data to determine top surface vertex to bottom surface vertex offset and center thickness to an accuracy of 0.1 micron

​

• Total measurement time <  5 sec per lens with line scan sensor

​

• Ideal for 100% inspection of lens-in-tray
