microscope in an upright position using both hands. **When carrying the microscope, place one hand on the base and the other hand around the arm. **DO NOT PLACE THE MICROSCOPE IN AN UPSIDE DOWN POSITION. PIECES WILL FALL OUT. **Keep microscope away from the edge of the bench, particularly when not in use. **Make sure power cords are out of the way.
PDF Introduction to the Microscope
forerunner of the compound microscope and the telescope. • 1665 - English physicist, Robert Hooke looked at a sliver of cork through a microscope lens and noticed some "pores" or "cells" in it. • 1674 - Anton van Leeuwenhoek built a simple microscope with only one lens to examine blood, yeast, insects and many other tiny objects.
1. State TWO procedures that should be used to properly handle a light microscope. 2. Explain why the light microscope is also called the compound microscope. 3. Images observed under the light microscope are reversed and inverted. Explain what this means. 4. Explain why the specimen must be centered in the field of view on low power before ...
PDF Lecture 4 to 5 MICROSCOPY-PRINCIPLES AND TYPES
(a) Simple microscope: It consists of only one bi-convex lens along with a stage to keep the specimen. (b) Compound microscope: It employs two separate lens systems namely, (i) objective and (ii) ocular (eye piece). 8.3.1.1. BRIGHT FIELD MICROSCOPE The compound student microscope is a bright field microscope. It consists of mechanical and
Care and Structure of the Compound Microscope
1. The microscope lens may be cleaned wjth any soft tissue. 2. The microscope should be stored with the oil immersion lens in position over the stage. 3. When beginning to focus, use the scanning objective lens. 4. When focusing on high power, always use the coarse adjustment knob to focus. 5. A coverslip should always be used with wet mounts. 4.
PDF Compound Microscope and Calculations
The Compound Microscope and Calculations The magnifying power of the eyepiece,(a.k.a.: ocular) is (10 x) ... Assignment Answer the following questions, showing all the steps. 1. A student is looking at a piece of string using the high power objective lens. She estimates that 5 pieces
PDF Care and Structure of the Compound Microscope
Compound Microscope The compound microscope is a precision instrument and should always be handled with care. At all times you must observe the following rules for its transport, cleaning, use, andstorage: . • When transporting the microscope, hold it in an upright position with one hand onits arm and the othersupporting its base.
PDF THE COMPOUND MICROSCOPE
THE COMPOUND MICROSCOPE. In microbiology, the microscope plays an important role in allowing us to see tiny objects that are normally invisible to the naked eye. It is essential for students to learn how to use the microscope in a skillful manner. Successful microscopy requires the student to: a. Be patient. b. Know the basic principles of ...
PDF Basic Observation Procedures for Compound Microscopes
13. When you have finished observations using the microscope, lower the stage, gently remove the specimen from the stage clips, lower the light intensity to its lowest setting, and switch offthe power. Wipe any dirty lenses clean using lens tissue onlv. with a drop of cleaning solution. Unplug the instrument and carefully wind the power
