A **bright field microscope** is a type of compound light microscope that illuminates the background against a stained specimen ¹². It is commonly used in practical labs to study organisms' behavior and characteristics such as size, shape, and arrangement ². The microscope uses light rays to produce a dark image against a bright background ¹. It is specially designed with magnifying glasses known as lenses that modify the specimen to produce an image seen through the eyepiece ¹. The bright field microscope is made up of various parts, including the eyepiece, objective lenses, focusing knobs, and stage ¹. I hope this helps!
