Within the scope of EURAMET calibration guidance documents, which have an important usage area all over the world, a calibration guidance document prepared under the leadership of TÜBİTAK UME was published for the first time for autocolimators, which are precision optical angle measuring devices.
Within the scope of the European Union Framework Programs, the guidance document prepared as one of the outputs of the international 16-partner "SIB58 Angles Angle Measurements Project" coordinated by Assoc. Prof. Tanfer YANDAYAN from TÜBİTAK UME and published under the title EURAMET Calibration Guide No. 22 Calibration of Autocollimators "Calibration of Autocollimators" was published on the EURAMET (European Association of National Metrology Institutes) website linked below in July 2017.
Using the previous work of TÜBİTAK UME Dimensional Laboratory and other national metrology institutes and the research conducted in the SIB58 Angles project for high-level nanoradian angle metrology, the guidance document was made available to meet the needs of a wide range of institutions ranging from second-level calibration laboratories to scientific institutions conducting high-level research.
In addition to the calibration of optical tooling, adjustment, angle measurement standards and devices in the industry, autocollimators, whose calibration is mentioned in the guidance document, have a wide range of applications in high-level scientific studies, space, aerospace and defense industries. Autocollimators are used in nanoradian angular adjustments of mirrors and optics used in space studies by institutions such as NASA, in the preparation of mirrors used to guide X-rays in accelerator centers such as CERN, in the calibration of accelerometers used in satellites sent to the planets, in material structure studies using gamma rays, in force measurements at the nanonewton level, in the experimental determination of the gravitational constant, and in performing precise angle measurements without contact.
The European Accreditation Association calibration guide documents, known as "EAL or EA calibration guides" in our country, were included in the scope of EURAMET, which prepared the documents since the mid-2000s, and started to be published as "EURAMET Calibration Guide" instead of EAL/EA.
TÜBİTAK UME, which started its metrology studies by using existing guidance documents in the 1990s when it was established, continues its research among the advanced level national metrology institutes by carrying it to the level of a prestigious institution that produces information and prepares such documents for Europe and the world.
