RIKEN Center for Advanced Photonics Ultrahigh Precision Optics Technology Team

Team Leader: Yutaka Yamagata (D.Eng.)

Research Summary

Yutaka  Yamagata(D.Eng.)

Our team develops advanced ultrahigh-precision/micro fabrication technologies and their application to scientific apparatuses and devices to support advanced scientific research at RIKEN. Research and development plans of our team include the following four topics: (1) Development of ultrahigh-precision optics including design, fabrication, metrology and computational simulation; (2) Development of ultrahigh-precision/micro fabrication technologies; (3) Development of fabrication technology for soft materials using the electrospray deposition method; and (4) Development of materials and devices for biology or biochemistry such as microfluidic immunoassay devices.

In all R&D topics, our team collaborates with laboratories inside and outside of RIKEN and helps them to construct the most advanced experimental apparatuses, which will lead to innovative scientific research results.
