Measurement of a Lens Stack

MEASUREMENT OF MULTIPLE LENS THICKNESSES AND AIR GAPS WITHIN A LENS STACK

The camera lens stack manufacturing process relies heavily on polished lenses that have precise thicknesses and distances between individual lenses.

The OptiGauge® II, is capable of measuring both lens thickness and distance between lenses with sub-micron precision. Combined with custom software and a precision stage, a lens stack can be characterized in terms of lens thickness and distance between lenses.
