A polarimeter is an instrument that measures the optical rotation of a substance. Optical rotation is the property of a substance to rotate the plane of polarized light. The amount of rotation is measured in degrees and is called the specific rotation. In this article, .Todd Research offers a range of high quality handheld metal detectors (also known as ‘metal detection wands’) for use in conjunction with metal detector archways or in isolation for certain applications. Currently we offer three models, with each option satisfying varying requirements to suit a range of customer locations and threat types. An easily constructed and inexpensive polarimeter with an optical rotation angle resolution of about 0.5° is presented. It is made from small pieces of polarizing film, 2 LEDs, a protractor, and a few wires, all held in place with plastic interlocking toy bricks, such as Lego bricks. The instrument was used to demonstrate the optical rotation of plane polarized light as .HARP2 (Hyper-Angular Rainbow Polarimeter #2) is a wide angle imaging polarimeter designed to measure aerosol particles and clouds, as well as properties of land and water surfaces. The amount and type of particles in suspension in the atmosphere are relevant to applications pertaining to health effects, cloud life cycle and precipitation .
A polarimeter measures the direction and extent of the polarisation plane rotation. Depending on the type of instrument, the analyser is rotated manually or automatically until the maximum intensity of the light falls on the detector. A polarimeter is the entirety of light source, polariser, polarimeter tube, analyser and detector. In this paper we show how measurements made by a simple handheld polarimeter in conjunction with automated sunsky radiometers can be used to effectively constrain the real part of the complex refractive index of aerosols. We find that even measurements over a limited angular range near 90° scattering angle are sufficient for this purpose. Laurent’s Half-Shade Polarimeter is an optical instrument used to measure the optical rotation of substances, typically liquid solutions containing optically active compounds. These compounds have the ability to rotate the plane of polarization of linearly polarized light, a property that can be exploited to determine the concentration, purity, or specific rotation of the .
Handheld Digital Polarimeter .
