SPECTROMETRIC APPARATUS

PROBLEM TO BE SOLVED: To provide a highly-versatile spectrometric apparatus having a simple structure of switching transmissive and reflective measurements and having a small size. SOLUTION: The spectrometric apparatus includes laser, light divider dividing a laser beam into a first divided light and a second divided light and outputting the first and second lights, a delay means applying a changeable time lag to the second divided light, an electromagnetic wave radiator radiating an electromagnetic wave by outputting the first divided light, a measurement sample arranger selectively arranging a measurement sample to a transmissive position where the electromagnetic wave transmits the measurement sample and a reflective position where the electromagnetic wave reflects at the measurement sample, a first detector inputting the lagged second divided light and the transmitted electromagnetic wave and outputting the detected signal, and a second detector inputting the lagged second divided light and the reflected electromagnetic wave and outputting the detected signal.
