Microscopes, Light, Laboratory
Definition : Light microscopes used in the clinical laboratory. These microscopes consist of a stand that supports the main components of the instrument, an ocular body (head) in which the eyepieces are mounted, a nosepiece to support the objectives, a specimen stage, a condenser to focus the light on the specimen, and the light source (e.g., tungsten, halogen) and light port. Laboratory microscopes may have only one ocular for visual observation or photography, two oculars for visual observation (binocular), or a third ocular (trinocular) incorporated for photomicrographic, observation, or teaching purposes. These microscopes may include multiple observation capabilities and optical integration of still, motion picture, and TV cameras. Magnification is the product of the power of the objective and ocular (sometimes an additional lens is used, in which case magnification is the product of all three lenses). Most laboratory microscopes use interchangeable or multiple-use parts (e.g., objectives, condensers), permitting the observation of samples using several contrast methods (e.g., dark field, phase contrast).
