RADIATION MIRROR DEVICE AND METHOD FOR USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a radiation mirror device capable of reflecting electromagnetic waves in the infrared range without damaging a reflecting surface even if radiant beams of high brightness impinge thereon. SOLUTION: This device has a mirror main body 13 with a flat reflecting surface 14, and a groove 15 extending in a straight line on the reflecting surface 14 and deeply dented into the mirror main body 13 is formed in the mirror main body 13. The mirror main body 13 is disposed so that the center portion 18 of a radiant beam can diagonally impinge on the sidewall 16 of the groove 15 and the peripheral edge portion of the radiant beam S can diagonally impinge on the reflecting surface 14.
