Development of the fast astigmatic auto-focus microscope system
Wei-Yao Hsu,Chien-Shing Lee,Po-Jui Chen,Nien-Tsu Chen,Fong-Zhi Chen,Zong-Ru Yu,Ching-Hsiang Kuo,Chi-Hung Hwang +7 more
TL;DR: In this article, a collimated infrared laser beam was employed in the infinite-corrected microscope optical axis by the beam splitter and reflected by the sample surface, and the reflected laser beam has different focal lengths in the sagittal and tangential planes.
