PROBLEM TO BE SOLVED: To obtain an ATR infrared spectrum measuring apparatus in which an ATR crystal is protected against damage due to over tightening of a solid sample and the tightening of solid sample can be regulated easily and a tightening force can be applied uniformly. SOLUTION: The ATR infrared spectrum measuring apparatus comprises a body 1A, a base plate 2 fixed detachably onto the body 1A, an ATR crystal 4 secured detachably through a stop plate 6 to a mounting face 5 having high surface accuracy provided on the base plate 2, a holder 10 moving up and down with respect to a solid sample 8 mounted on the ATR crystal 4, a stopper plate 14 for urging the holder 10 downward through a repellent member 13, and a member 17 for moving the stopper plate 14 up and down. |
