Benchmarking instrumentation tools for the characterization of microlenses within the EC Network of Excellence on Micro-Optics (NEMO)

Abstract

Today there exist different commercial micro-optics measurement instruments for the characterization of micro-optical components and microlenses in particular. However there is often a lack of a complete quantitative optical characterization of the latter components. Therefore we will focus in this paper on the optical characterization of all types of refractive microlenses, more in particular spherical and aspherical microlenses. Moreover the results of the performed round robin within the European 6th FP Network of Excellence on Micro-optics "NEMO" will allow us to select the most appropriate instrumentation tools for characterizing refractive microlenses.

“…Nonetheless, a main issue about optical methods is their lack of traceability, and therefore comparison measurements, including tactile methods, as well as comparisons limited to different optical instruments, frequently reveal significant deviations of the reported results [23][24][25][26][27][28][29][30][31]. An explanation of the deviations between the optical and the tactile methods might be that the latter probe the mechanical surface, whereas optical methods probe the electromagnetic surface [32].…”
