About us

The Sectrography and BioImaging facility manages the research tool using "Light".
Specially, Okazaki Large Spectrograph (OLS) is the largest spectrograph in the world. The spectrograph dedicated to action spectroscopical studies of various light-controlled biological processes. The spectrograph runs on a 30kW Xenon arc lamp and has a compound grating composed of 36 smaller individual gratings. It projects a spectrum of a wavelength range from 250nm (ultraviolet) to 1,000nm (infrared) onto its focal curve of 10m in length. The fluence rate (intensity) of the monochromatic light at each wavelength is more than twice as much as that of the corresponding monochromatic component of tropical sunlight at noon (Watanabe et al., Photochem. Photobiol. 36, 491-498, 1982).


We also provide user support and management of imaging equipment such as optical microscopes and micro CT. Bioimaging has become an essential tool in modern biology. On the other hand, microscopes have become more complex and multifunctional, requiring specialized knowledge to handle them. The quantitative data also requires expertise in optics and image analysis. Therefore we offer training courses to provide the know-how for microscope image acquisition, and we also collaborate with specialists for special microscopes and image analysis. Please feel free to contact us if you have any questions about imaging.
