Our expertise lies in providing comprehensive maintenance and calibration services for industrial use microscopes, especially those operating in harsh factory environments. Our routine maintenance program includes thorough cleaning of all accessible optical surfaces and reconditioning of mechanical assemblies to restore even the most unusable microscopes to like-new condition. As an accredited calibration provider to ISO/IEC 17025:2017 and ANSI/NCSL Z540-1, we adhere to the highest standards of quality assurance. Our calibration process involves the use of certified reference materials that are traceable to the International System of Units (SI) and we calculate calibration uncertainties per magnification per microscope, taking into account uncertainty contributors such as system noise from instrument instability, reference material imperfections, thermal expansion, spatial resolution, optical aberrations and distortions, and magnification errors of the units under test. In addition, we provide measurement risk assessment services and utilize the method 6 decision rule to establish guard banded customer tolerances when making statements of compliance, which guarantees a probability of false acceptance equal to or less than 2%.
