Polariscope | Perfectgroupindia

An optical tool called a polariscope is used to investigate the polarisation of light. Using a light source before the first filter and an analyzer in front of the second filter, it typically comprises two polarising filters positioned at right angles to one another. The polariscope can provide details about the structure and makeup of materials that impact the polarisation of light traveling through them by observing changes in the brightness and color of the transmitted light. <br>Visit:- https://www.perfectgroupindia.co.in/polariscope.php<br>

  1. Polariscope Polariscope is a scientific instrument used to study the optical properties of materials. It is widely used in various industries, including gemology, plastics, and glass manufacturing. Presented By: Perfectgroupindia

  2. History of Polariscope Polariscope was invented in the 19th century by Étienne-Louis Malus, a French physicist. He discovered the polarization of light in 1808 and developed the first polariscope in 1810. Since then, Polariscope has been used extensively in various fields of science and industry. The polarized light reflects off the sample and is then analyzed by the analyzer. This type of Polariscope is used to study the birefringence of opaque materials.

  3. Birefringence and Optical Path Difference Birefringence is the property of materials that have two different refractive indices for polarized light. When polarized light passes through a birefringent material, it splits into two waves, each with a different velocity and polarization. Optical path difference is the difference in the length of the optical path traversed by the two waves of polarized light passing through a birefringent material. The optical path difference determines the interference pattern observed through the polariscope.

  4. Types of Polariscope Transmission Polariscope In transmission Polariscope, the light source is placed behind the polarizer, and the sample is placed between the polarizer and the analyzer. The polarized light passes through the sample and is then analyzed by the analyzer. Reflection Polariscope In reflection Polariscope, the light source is placed in front of the polarizer, and the sample is placed in contact with the analyzer. The polarized light reflects off the sample and is then analyzed by the analyzer. This type of Polariscope is used to study the birefringence of opaque materials.
