Study of light-harvesting dynamics in photosynthetic system with cryogenic two-photon excitation microscope

我成功地研制了一种新型的生物光学显微镜，其数值孔径为0。9首次在低温下运行。所开发的显微镜即使在液态He温度下也能以300 nm的空间分辨率对生物样品进行显微镜观察。该系统配备了一个色差校正物镜透镜，然后优化时空分辨光谱的应用。

I have succeeded to develop a novel biological optical microscope with a high numerical aperture of 0. 9 operative at cryogenic temperature for the first time. The developed microscope enables the microscope observation of biological samples with a 300-nm spatial resolution even at liquid He temperature. The system is equipped with a chromatic aberration corrected objective lens, and then optimized for the application of the time-space-resolved spectroscopy.
