movement of the stage when using the fine adjustment knob The coarse moves the stage at a fast level and the fine at a slower level When is it appropriate to use the coarse adjustment knob? It is apporatiate to use coarse on low power. Which objective lens do we begin with when viewing a slide?

Lab Title: Microscopy Objective: To learn how to use and care for a microscope and to know the parts of a compound microscope and to efficiently use the microscope to focus on specimen. Introduction A microscope is an optical instrument used for viewing very small objects‚ typically magnified several hundred times. It consist of different lenses such as: Scanning = 4X‚ Low power = 10X‚ High power = 40 or 43X‚ Oil Immersion = 100X. A microscope is an instrument

The ocular micrometer has no units. 5. Objective lens The objective lens gathers light from the specimen‚ magnifies the image of the specimen‚ and projects the magnified image into the body tube. Since no single objective lens can fulfill all the needs of someone using the microscope‚ several objective lenses of varying magnifications and numerical aperture are mounted on the rotation nosepiece. The nosepiece must click into place for the objective lens to be in proper alignmrnt. You will

microscope is plugged in and placed on the lab bench in front of the user to the point at which the slide is being clamped onto the stage. One can assume that the microscope is set up such that the stage is in its lowest position and that the low power objective is locked into place. 2. a) State the steps one would follow to achieve an efficient and ‘quick’ focus of a prepared slide in which the letter ‘K’ has been mounted.

Eyepiece tube holds the eyepieces in place above the objective lens. Binocular microscope heads typically incorporate a diopter adjustment ring that allows for the possible inconsistencies of our eyesight in one or both eyes. The monocular (single eye usage) microscope does not need a diopter. Binocular microscopes also swivel (Interpupillary Adjustment) to allow for different distances between the eyes of different individuals. * Objective Lenses are the primary optical lenses on a microscope
