Experiment 1: Introduction to Interferometry EQUIPMENT NEEDED: OS-9255A Basic Interferometer (OS-9255A) – Laser (OS-9171) – Laser Alignment Bench (OS-9172) – holder InterferometerAccessories(OS-9256A) – Component Holder , (2) Calibrated Polarizers Introduction In general, an interferometer can be used screen in two ways. If the characteristics of the light source are accurately known (wavelength, Lens 18mm FL polarization, intensity), changes in the beam mirror path can be introduced and the effects on the interference pattern can be analyzed. Experi- ments 2 and 3 are examples of this Adjustment procedure. On the other hand, by introducing specific changes in the beam path, information can be obtained about the 1 div = 1 MICRON light source that is being used. In this experiment, you'll use the interferometer to Beam splitter measure the wavelength of your light mirror source. If Thumbscrews you have a pair of polarizers, you can also investigate the polarization of Micrometer your source. knob Procedure Figure 1.1. Michelson Mode Setup Part I: Wavelength
