An Affordable Indigenous Polarizer-Analyser System with Inbuilt Retardation Plate Function to Detect Birefringence using 3D Glasses: An Experience

摘要

IntroductionPolarizing microscope plays a vital role in few but unique situations. A pair of cross polarizers is used to confirm the presence of birefringent substances. Also, a red retardation plate is needed to evaluate the sign of birefringence. However, a polarizing microscope especially with retardation plate is very expensive. Thus, an affordable yet effective substitute using the 3D Polaroid glasses used for ‘3D movies’ would enable widespread use of the polarizing system.
