1.	Which of the following is not the function of the drive mechanism in Fourier Transform Infrared Spectrophotometer?(a) Movement of mirror to obtain a satisfactory interferogram(b) Acquire a good interferogram pattern(c) Allow 50% of the beam to pass(d) Keep the speed of the moving mirror constantThis question was addressed to me in a job interview.The above asked question is from Fourier Transform Infra-red Spectrometers topic in chapter Colorimetry and Spectrometry of Analytical Instrumentation
Answer» Correct option is (c) Allow 50% of the BEAM to pass To explain: Drive mechanism does the FUNCTIONS SPECIFIED in the other OPTIONS. It the function of the beam splitter to allow 50% of the beam to pass through.
