Olympus Aids Development of Reference Standards
The 'Optassyst' project – user-oriented assistance systems for the reliable use of interferometric and confocal distance sensors in the industrial production environment project – aims to develop a software-based user-friendly assistance system for three-dimensional optical geometry recording on technical surfaces. In cooperation with industry and university partners, the PTB is developing a system to provide users with a valuable resource. It will aid in the instrument set-up, use of advanced signal processing and the application of calibration strategies and characteristic 3-D variables, helping users to improve their understanding of topographic measurements.
Three-dimensional surface measurement technology is essential for the accurate recording of the optical geometry of technical surfaces. In systems such as a combustion engine, the degree of efficiency is dependent upon surface quality. The functional behaviour of surfaces under such a high thermal load is therefore optimised by specifically modifying the surface topography. As a result, understanding the topographical measurements is pivotal to this process and will be greatly facilitated by the results of this project.
By using the LEXT OLS4000 as a representative for confocal laser scanning microscopes in this project, resolution and measuring uncertainties of features on surface topography standards will be determined. With its excellent X/Y and cutting-edge Z performance, the LEXT OLS4000 provides a fast and powerful way to research and characterise these standards. This unique tool will therefore enable users to accurately interpret measurement results.
