Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
This paper introduces cost-effective and flexible manufacturing techniques for producing a defect-free microlens array (MLA) using different optical materials, including norland optical adhesive (NOA), polymethyl methacrylate (PMMA), and borosilicate glass P-BK7. The investigation showed that by using a proper mold, defect-free NOA, PMMA, and optical glassMLA with various geometries can be efficiently manufactured by a polymerization or a precision glass molding (PGM) process. The investigation reveals that the surface quality of NOA MLA can be significantly improved by adjusting the viscosity of the NOA monomer solution. By optimizing the viscosity, defect-free MLA of high quality can be achieved. Furthermore, the study shows that high-quality PMMA and PBK7MLAcan be obtained by carefully controlling the molding temperature and pressure during thePGMprocess. The appropriate adjustment of these parameters ensures the successful fabrication of MLA with excellent surface quality and without any defects.
