LOWER the condenser INCREASE the contrast What are the three main steps involved in urinalysis? 1. Physical assessment: - Amount - Color - Clarity - Smell - S...

Bright Field Microscope CORRECT ANSWER Most widely used Dark object, bright background Examine stained and unstained specimens Made by putting light through specimen Dark field microscope CORRECT ANSWER Image is lighter than illuminated background Uses a condenser on the light microscope Phase contrast microscope CORRECT ANSWER Used with live specimen Produces image with specimen against gray background Can see internal cells Scanning electron microscope CORRECT ANSWER Detailed 3D...

Why is oil immersion used? To reduce the amount of light rays that are refracted away from the objective lens. It increases numerical aperture and maintains a uniform light speed. increase the resolving power of a microscope. Prevents refraction of light. What parts of the microscope does light travel through? Illuminator-The light source for the microscope.Diaphragm-Controls the amount of light entering the condenser. Condenser lensFocuses light through the specimen. How do you calculate t...

Who is the father of microscopy? Antonie van Leeuwenhoek Lamp: produces visible light to illuminate the specimen Condenser: collects light and directs it through the stage opening (converges or focuses the rays of light to a single point) Iris diaphragm: regulates the amount of light available to the objective lens Factors that affect microscope function: Resolving power, numerical aperture, magnification, working distance Resolving power: ability of a microscope to differentiate two ...
