Polarizer vs. Analyzer: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 23, 2023
A polarizer selects a specific plane of light waves; an analyzer detects or measures light's polarization state.

Key Differences

A polarizer is a device or filter that only allows light waves vibrating in a specific plane to pass through. On the other hand, an analyzer is an optical component used to measure or detect the polarization state of light.

The polarizer's primary role is to produce light of a specific polarization from unpolarized light. In contrast, the analyzer's main function is to study or analyze the characteristics of light that has been polarized.

When using polarized light in experiments, a polarizer is generally the first optical element that transforms the unpolarized light into polarized light. An analyzer, however, comes after, allowing researchers to observe the effects or characteristics of the polarized light.

Polarizers can be found in various everyday applications, including sunglasses and camera filters, where they reduce glare and improve image clarity. Analyzers, on the other hand, are more commonly found in scientific instruments and specialized devices to determine the polarization properties of light.

While both the polarizer and analyzer interact with polarized light, their roles are distinct: the polarizer creates the polarized light, and the analyzer investigates or measures it.
