This document describes a procedure to determine the specific rotation of sugar using a Laurent's half shade polarimeter. Key steps include: 1) Cleaning and filling a polarimeter tube with a sugar solution of known concentration 2) Passing plane-polarized light .position inside the polarimeter. Switch on the source of light and look through the eyepiece. • In case of half shade polarimeter, two halves of unequal intensity is observed. Left half may be bright and the right half may be dark, or vice versa. By rotating the analyzer eyepiece system, About this video__In this video we will discuss about:-Laurent's half shade polarimeter which is used to measuring the optical rotation of optically active s.Half shade principle Optical rotatory power Optical activity Specific rotation Aim of the experiment To determine the specific rotation of an optically active substance by polarimeter. Apparatus required A Polarimeter Optically active substance (known weight) A measuring cylinder A beaker A scale Distilled water Sodium light source Theory
POLARIMETERThe Polarimeter consists of Monochromatic source of light usually a sodium lamp. This light is allowed to pass through a narrow slit and then to N.Half Shade Polarimeter is a useful apparatus for understanding the concept of polarization. With the help of half shade polarimeter, polarization can be studied as well as analyzed. For better accuracy in determination of specific rotation, half shade polarimeter is used which involves comparing the brightness of two halves in the field of view #Polarimeter#ICSirPhysics#ICSirClassesPolarimeter | Half Shade Device Polarimeter || Biquartz Polarimeter | Optical Rotation for B.Sc. 2nd🔷🔷🔷🔷#HalfShadeP.
In our improved polarimeter (Figure A4.7), a half-shade device has been placed , which has been oriented at an angle of -85º. The emerging polarized light then passes through the glass-half of the half-shade lens and emerges unchanged. As it passes through the quartz-half, however, it is rotated by 2θ and emerges at an angle of 85º. Laurent’s Half Shade Polarimeter. Pada jenis polarimeter ini, terdiri dari setengah lingkaran dan setengah gelombang piring sudut ABC kuarsa (potong sejajar dengan sumbu optik) sehingga dapat menghasilkan perubahan fase dariantara sinar luar biasa dan sinar biasa yang melewati itu, dan pelat kaca setengah lingkaran ADC. .

Various concentrations of sugar solution were tested between 0.025 g/cc and 0.4 g/cc. The specific rotation . comparison, Laurent's Half-shade Polarimeter, Bi-quartz PolarimeterA polarimeter consists of two Nicols termed as polariser and analyser. These can be rotated about a common axis and the substance for which the rotation is to be determined, is placed in a tube in between these two. The half shade plate is placed between the polariser and the solution tube (cf., Fig. 3).

Half Shade Polarimeter. It consists of two nicol prisms N 1 and N 2. N 1 is a polarizer and N 2 is an analyzer. Behind N 1, there is a half wave plate of quartz Q which covers one half of the field of view, while the other half G is a glass plate. The glass plate G absorbs the same amount of light as the quartz plate Q.T is a hollow glass tube having a large diameter at its middle portion.The half-shade is a device that transforms the total extinction point into an equal illumination of two adjacent fields. This mode of detection was superior for manual polarimeters, since the human eye is much more adept at balancing fields of transmitted light than at detecting a minimum in light intensity.
