Laboratory light microscopes in which the use of polarized light enhances contrast and makes visible details otherwise difficult to see, especially in the analysis of anisotropic or birefringent specimens. As a result of destructive interference contrast or color results, they can provide information on the condition and structure of the specimen. Some polarized light microscopes can also be configured for Brightfield and/or phase-contrast observation. These microscopes are used in microbiology (fungi are birefringent), cytology (wet mounts) and in urinalysis (birefringent crystals such as uric acid).
