Polarimeter
Polarimeter Instrument Is For Measurement Of
Optical Rotations, For Study Of Polarisation Effects And For Quick And Easy
Determination Between Right-Handed Sugars Such As Dextrose And Left Handed
Sugar Such As Fructose. Instrument Essentially Consists Of A Pair Of
Polarizes Arrange In A Straight Line, One Of Which (Analyzer) Can Be Rotated
With Respect To The Other (Polarizer) And The Rotation Measured On A Divided
Circle. The Analyzer Is Rotated Till It Is Crossed With The Polarizer. In
This Position The Planes Of Polarization Of The Polarizer And The Analyzer,
Are Mutually Perpendicular, So That There Is No Transmission Of Light Across
The Pair. Now If A Tube Containing An Optically Active Solution Is
Introduced Between The Polarizer And The Analyzer, The Light Transmission Is
Partially Or Wholly (If The Optical Rotation Of The Liquid Equals 90o)
Resorted. The Analyzer Is Rotated Again To Obtain The No Transmission
Position. This Rotation Equals The Optical Rotation Of The Liquid. Since It
Is Difficult To Recognize The Actual No Transmission Position, One Is Able
To Obtain A Range Only For No Transmission. The Definition Of This Range Is
Quite Subjective. To Overcome This Difficulty, In Modern Polarimeters, An
Extra Device Is Used. This Device Is A Half-Wave Plate, Covering Half Of The
Circular Field Of View. This Plate Introduces A Certain Path Difference
Between Light Waves In The Two Halves Of The Field Of View. Thus When The
Analyzer Is Rotated The Intensity In One Half Of The Field Of View Is
Extinguished Slightly Before The Other Half. At This Point It Is Easy To
Continue Rotation Of The Analyzer To Obtain A Uniform Illumination Of The
Field Of View. This Position Can Be Determined Quite Accurately And Is Used
As The Desired Position. The Optically Active Substance (Solution) Is Now
Introduced Between The Polarizer And The Analyzer And The Uniform, Field Of
View Position Is Determined Again To Obtain The Optical Rotation Of The
Liquid. The Circular Scales Are Finely Marked On A 10cm Diameter Circle Both
In Angular Measure And In International Sugar Scale. The Smallest Division
On Angular Scale Is 1 O ISS. The Sugar Scale Is Calibrated Between 30 O (For
Levorotary Substances) And +130 O ISS. A Divided Of 0.05o (3 Minutes) On The
Angular Scale And 0.1 O ISS. The Scale Is Properly Illuminated To Facilitate
Reading. Length Of Tubes Is 220mm Have A Bubble Trap. Polaroid Sheets Used
For Polarizing The Incident Light. Glass Circular Scale Finely Marked In
Angular Degrees And Also In ISS Degrees. The Range On ISS Scale Is From 30 O
+ 130o . Permanent Focus: Once The Dividing Line Is Focused For The Eye. The
Focus Is Not Disturbed By Inserting Tubes Containing Solutions, Regardless
Of The Nature Of Solution Or Of The Length Of The Tube Permanent Good
Definition Even With Difficult Liquids Rotating Half Shadow Effect Provision
For Attaching Lamp To The Instrument Thus Keeping Alignment Correct At All
Times.Electric Supply Work On 220/230 Volts, 50/60 Hz AC
