<p><P>PROBLEM TO BE SOLVED: To provide a total reflection absorption spectrum measuring device equipped with a means capable of switching an ATR observation mode to/from a visual observation mode accurately with a simple mechanism. <P>SOLUTION: This total reflection absorption spectrum measuring device equipped with a reflection object optical system comprising a concave main mirror 2 and a convex sub-mirror 3, and an ATR prism 4 having a total reflection face on a converging point of the optical system, has a constitution wherein a holder 7 for holding the ATR prism 4 is mounted on a rotating shaft 6, and the rotating shaft 6 is formed so as to be rotated around a horizontal line on the sample surface S placed on the under surface of the ATR prism 4, and the ATR prism 4 can be inverted and moved from a sample measuring position to a retracting position on the upside by rotating the rotating shaft 6. The device has a structure wherein a light transmission means (for example, a hole) 11 for allowing passage of measuring light when the ATR prism 4 is on the retracting position is formed on the holder. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
