Interferometry - UKAS Class A

Alan Browne Gauges are UKAS Accredited to calibrate Grade 00 & K to Class A interferometry.
Class A uncertainties apply to the measurement of length by interferometry of grade K gauge blocks to BS EN ISO:3650 and BS4311:2007, when they are measured twice, wrung to a platen by each of the two measuring faces in turn, and the mean of these two measurements stated on the certificate.
