UKAS Calibration Service
Opus has one of the largest (162m²), best equipped UKAS Accredited Calibration Laboratories in the UK.
It is temperature controlled at 20° ±1°C and locally for some specialised measurements at ± 0.5°C.
Opus offers two types of service:
• A Laboratory-based Calibration service at Corby for portable measuring instruments.
• An On-Site Calibration service for larger instruments including Surface Plates,Surface Tables, Profile Projectors and other large items.
Additionally, to avoid being without instruments for extended periods of time, we also offer a “Pre Booking Service” for both Laboratory based and On-Site Calibration which reserves a calibration slot in our schedule.
Please contact us for further details of our “Pre-Booking Service”

CALIBRATION OF GAUGE BLOCKS BY INTERFEROMETRY
Gauge blocks play a crucial role in maintaining traceability to the ‘Metre’ in dimensional metrology. The most accurate method for calibrating the length of a gauge block is to use optical interferometer. Here at OPUS we offer length of gauge blocks that are measured by the gauge block interferometer (Hexagon / NPL). A two frequency stabilized He-Ne lasers are used as the illumination. The measurement chamber environment is controlled and the temperature is kept constant at 20±0.5C.
Length of gauge blocks from 0.1 mm up to 100 mm can be measured in Accordance to BS EN ISO 3650:1999 and BS 4311-1:2007
