Absolute Metrology Services

A Woman-Owned Business


Absolute Metrology Services has extensive experience with interferometry and optical testing. Over the past 15 years we have worked with large aperture interferometers and interferometric microscopes, from general optical testing of customer parts to high-level absolute reference calibrations for customers who own interferometers. We take great pride in offering basic and advanced interferometry training for customers with interferometers as well.
