What is the polarimeter?

Polarimeter is a scientific tool for measuring the amount of light received at a particular point. It depends on what direction or polarization they can have different light waves when the source is reached. The process of light polarization first discovered in 1808 Etienne-Louis Malus, a French physicist, while one of the first functional polarimeters to measure the effect was performed by Jean-Baptiste Biot, another French physicist, in 1816 he was improved in 1816 in 1816. The progression of the Polarimeter design since the 1980s. It led to a digital polarimeter and automatic polarimeter, which is controlled by computer and has electronic readings. The samples used to measure the effect must be partially transparent. They have a wide range of shapes and sizes, but the basic principle is the same. The beam of the unpopular light is reflected from the mirrors and thus lifts with solid crystals or transparent liquid samples that break it into polarized light.

Since the light waves are polarized in the basic polarimeter, the diameter of the tube is routed 4 inches (10 centimeters) on average, which contains a studied chemical. If the compound has polarizing properties, the brightness of the light will reduce how its output angle changes from the tube. This angle is then determined by rotating the analyzer axis at the end of the tube. If the angle change is considered to be positive or to the right, it is called dextrorotive, and if it is left, it is referred to as levo -herooting. The size of the angle of rotation is determined by the length of the tube type and the concentration of the compound, which passes through the light, known as Enantiomer.

In applications with fine tolerance, such as ophthalmology, a laser polarimeter or optical polarimeter is built into an ophthalmoscope and uses a nearby infrared laser to determine the ability to compensate polarized light. This is useful in monitoring such degenerative eye conditions as glaucoma. The results areThen analyzed using statistical software to try to anticipate the onset of glaucoma before physical symptoms are present in the patient.

Because many compounds show the rotation of the light that passes through them, the polarimeter has a wide range of applications in the pharmaceutical, food and chemical industry in general. They are routinely used to determine the level of cleanliness of medicinal products such as antibiotics, concentrations of sugar and flavors in various food produced and to identify the polymer concentrations in the Plasttechnics.
