In physics and engineering laboratories, precision measurement is critical. One such highly accurate instrument used for linear and angular measurements is the travelling microscope. If you’ve ever wondered what a travelling microscope is and how professionals take accurate travelling microscope reading, this guide explains everything in simple terms.Whether you are a student, lab technician, or researcher, understanding this instrument can significantly improve measurement accuracy in experiments.What Is Travelling Microscope?A travelling microscope is a precision optical instrument used to measure very small distances with high accuracy. It consists of a microscope mounted on a movable carriage that slides along a graduated scale.The instrument moves horizontally (and sometimes vertically), allowing users to observe and measure minute displacements in experiments such as:
