Description
This study presents the development of a sub-THz optical system for exposure experiments on corneal tissues at 265 GHz using a high-power gyrotron. The optical system includes phase-correcting mirrors, flat mirrors, an elliptical mirror, lenses, and a power control module. The target beam is designed to achieve a full width at half maximum (FWHM) of 4–6 mm and a vertical polarization direction at the sample position. Radiation patterns were measured using an infrared camera, and the FWHM of the beam was estimated to be 6.4 mm and 5.1 mm in horizontal and vertical directions, respectively. The results demonstrate that the beam size is useful for exposure experiments.
