Optical Activity Ltd. is a UKAS (United Kingdom Accreditation Service) accredited calibration laboratory and all of our polarimeters can be supplied, if required, with a UKAS certificate of calibration. The UKAS mark on a calibration certificate is your assurance that the laboratory issuing the certificate has been stringently assessed by independent experts and that measurements are traceable to national and international standards. You may also purchase Optical Activity quartz control plates with UKAS accredited calibration certificates for routine checking of your own polarimeters.
