PASCO Complete Interferometer System

Purpose: No study of interferometry should overlook the historical importance of the Michelson interferometer. Yet in the laboratory, the Fabry-Perot and Twyman-Green interferometers can be more important tools: the first for high-resolution spectroscopy; the second for testing and producing optical components with aberrations that can be measured in fractions of a wavelength. Key Features: - Stable: The massive (5 kg) base is machined from a single block of aluminum ensuring extremely stable optics - Smooth Mirror Movement: With the taut-band suspension system, there’s no starting or stopping friction and virtually no backlash (less than 0.5 micron) - Precise Measurements: Mirror control is extremely fine: one micron per division of the micrometer head - The mirrors and beam-splitter are flat to 1/4 wavelength to ensure uniform interference patterns - Larger Optics: The 3.2 cm (1-1/4") diameter optics in the PASCO Interferometer produce larger and sharper interference patterns for better experimental results - Complete: The Basic Interferometer includes everything necessary to perform basic Michelson and Fabry-Perot interferometry Educational Topics: Introduction to Interferometry The Index of Refraction of Air The Index of Refraction of Glass, Perform basic Michelson and Fabry-Perot interferometry Demonstrate that cross-polarized beams will not interfere Measure lens irregularities in Twyman-Green Mode Measure the indices of refraction for air and glass Measure the indices of refraction for user-supplied materials What's Included: 1× Hand Operated Vacuum Pump (OS-8502) 1× Mini Laser with Bracket (OS-8514) 1× Laser Alignment Bench (OS-9172) 1× Machined Base -- 5 kg 1× Three-Point Adjustable Mirror 1× Mounted Beam-Splitter 1× Mounted Movable Mirror 3× Accessory Mounts 1× Compensator Lens 1× Fitted Case 1× Gas Cell 2× Calibrated Polarizer 1× Glass Plate 1× Rotating Component Holder 2× Twyman-Green lenses 1× Instruction Manual
