Development of wideband spectral dispersers for exoplanetary science: comparative study of material, design, and fabrication

Keigo Enya Naofumi Fujishiro

NOVEL OPTICAL SYSTEMS DESIGN AND OPTIMIZATION XVII 9193 2014年

We present the development of wideband spectral dispersers of which the primary scientific objective is the characterization of the atmospheres of exoplanets, including the challenge of detecting biomarkers. A disperser comprising a prism with a g...

Quality evaluation of spaceborne SiC mirrors (II): evaluation technology for mirror accuracy using actual measurement data of samples cut out from a mirror surface

Masaki Kotani Tadashi Imai Haruyoshi Katayama Yukari Yui Yoshio Tange Hidehiro Kaneda Takao Nakagawa Keigo Enya

APPLIED OPTICS 52(26) 6458-6466 2013年9月 [査読有り]

The authors studied the quality evaluation technology of a spaceborne large-scale lightweight mirror that was made of silicon carbide (SiC)-based material. To correlate the material property of a mirror body and the mirror accuracy, the authors ev...
