Study of calibration and measurement capa-bility (CMC) of a Nikon electronic autocollimator

Abstract

In this work we study the results of the calibration of an electronic autocolimator developed in the Center of Research and transfer in Metrology -CEMETRO- of UTN FRC. The instrument is built on the basis of a commercial analog auto-collimator, Nikon 6D, and an ad hoc visual interface. The calibration was carried out at the National Angle Laboratory of Argentina, INTI Córdoba, with international traceability to the reference standard (Trioptics TA300 autocolimator). The analysis of the calibration results allows us to obtain a more accurate metrological model of the electronic autocolimator. In addition, it defines guidelines to optimize the performance of the instrument through design adjustments of the electronic visual interface connected to the Nikon 6D optical autocolimator.
