Bellingham + Stanley offer a choice of Quartz Control Plates (QCP) for verifying and calibrating polarimeters. QCPs are made to the highest standard and may be supplied with optional Certificates of Calibration showing traceability to PTB.  (UKAS Certificate calibrated in accordance with ISO/IEC 17025:2017 @ specified wavelength between 546-900nm; Manufacturers certificate at specified wavelengths between 300-545nm)

When used with an ADP polarimeter manufactured by Bellingham + Stanley, a thermal block may be used to provide mechanical contact to the instrument’s external temperature sensor, allowing the use of quartz temperature compensation for added accuracy. 

For added performance, an XPC Adaptor is also available for use with Peltier temperature controlled Bellingham + Stanley polarimeters that incorporate XPC Technology. 

As part of Good Laboratory Practice, it is recommended that Quartz Control Plates are sent to our UKAS laboratory at regular intervals determined by the user’s own Standard Operating Procedure for inspection and recertification.
