The three basic structural components of a compound microscope are the head, base and arm. I Ahead/ Body houses the optical parts in the upper part of the microscope I Base of the microscope supports the microscope and houses the illumination Arm connects to the base and supports the microscope head. It is also used to carry the microscope. I I When carrying a compound microscope always take care to lift it by both the earn and base, simultaneously. I OPTICAL COMPONENTS There are two optical systems in a compound microscope: Eyepiece Lenses and Objective Lenses: I Eyepiece or Ocular is what oh look through at the top of the microscope.
Typically, standard eyepieces have a magnifying power of lox. I lavational eyepieces of varying powers are available, typically from xx. Xx. I Eyepiece tube holds the eyepieces in place above the objective lens, Binocular microscope heads typically incorporate a adopter adjustment ring that allows for the possible inconsistencies of our eyesight in one or both eyes. The monocular (single eye usage) microscope does not I Indeed a adopter, Binocular microscopes also swivel (Interplanetary Adjustment) to allow tort different distances between the eyes tot different landslides. I Objective Lenses are the primary optical lenses on a microscope.
They range from xx-sanded typically, include, three, four or five on lens I Ion most I Incipience houses the objectives. The objectives are exposed and are mounted on a rotating turret so that different objectives can be conveniently selected. Standard objectives include xx, I Ox, xx and xx although different power objectives are available. I Coarse and Vine Pocus knobs are used to focus the microscope. Increasingly, they are coaxial knobs – that is to say they are built on the same lexis With the fine focus knob on the outside. Coaxial focus knobs are more convenient since the viewer does not have to grope for a different I knob.
I I Stage is where the specimen to be viewed is placed. A mechanical stage is used when working at higher magnifications where delicate movements I loft the specimen slide are required. I Stage Clips are used when there is no mechanical stage. The viewer is required to move the slide manually to view different sections of the I licensee. I Aperture is the hole in the stage through which the base (transmitted) light reaches the stage. For a microscope, typically located in the base of the microscope. Most light gyroscopes use low voltage, I halogen bulbs with continuous variable lighting control located within the base.
Condenser is used to collect and focus the light from the illumination on to the specimen, It is located under the stage often in conjunction I Twit an iris diaphragm. I Iris Diaphragm controls the amount of light reaching the specimen. It is located above the condenser and below the stage. Most high quality I microscopes include an Babe condenser with an iris diaphragm Combined, they control both the focus and quantity of light applied to the I I specimen. I Condenser Focus Knob moves the condenser up or down to control the sighting focus on the specimen.
