In terms of sophistication, polarized light microscopescan be categorized into three levels: small, highlycapable microscopes designed for education or basicanalytical work; laboratory grade, which allows fullpolarized light forensic analysis; and high grade laboratoryinstruments, which are also used for research.

Okapi are found only in the Ituri Rainforest, in the Democratic Republic of the Congo (formerly called Zaire), in central Africa. They live in tropical forests at fairly high elevations, between 1,500 and 3,300 feet. Okapi are nocturnal.By day, they stay in the impenatrable swamps and thickets.At night, they move up in elevation to drier, more open forests, where they feed on leaves from over 100 species of plants. By getting food from such a diverse array of plants, they help ensure they can find enough food.kapi are nocturnal. By day, they stay in the impenatrable swamps and thickets.
