The polarized ring light minimizes unwanted glare and reflections from shinyor reflective surfaces, such as glass or metal. By controlling the polarizationdirection, you can effectively eliminate or significantly reduce thesedistracting elements, allowing for clearer visualization of the specimen. Thishelps to highlight specific details and structures in the sample, making themmore visible and easier to observe. The first image is without polarized light, the second is with polarized light.
