Lab 2: measurement and counting of cells using microscope 21 ocular micrometer introduction ocular micrometer is a flat disk of glass that fits into the one of the microscope eyepieces the purpose is to measure the size of the magnified object. Lab 2 : measurement and counting of cells using microscope 21 ocular micrometer introduction an ocular micrometer is a glass disk that fits in a microscope eyepiece that has a ruled scale, which is used to measure the size of magnified objects under the microscope especially in measuring and comparing the size of prokaryotic and eukaryotic. Focus the microscope on the scale of the ruler, and measure the diameter of the field of vision in millimeters record this number when you are viewing an object under high power, it is sometimes not possible to determine the field of view directly the higher the power of magnification, the smaller the field of view.
Measuring with a microscope reticle measuring with the microscope is simple when you understand a few steps to take before using your microscope eyepiece reticle prior to making any measurements you will want to calibrate your microscope with a stage micrometer. 1 lab 2 microscopic observation of cells prelab assignment 1 before coming to lab, read carefully the introduction and procedures of each part of the experiment if you and your group members are not familiar with the procedure before biology 100 microscope lab – page 2 of 11.

Transcript of lab 1 introduction to microscopy and the cell lab 1 introduction to microscopy and the cell - make sure to gain good understanding on microscope use (it will be on the lab final) - purpose of calibration: estimate the distance across one ocular space to use as ruler to measure - ocular micrometers are limited - ask ta. Linear measurements (micrometry) the first reported measurements performed with an optical microscope were undertaken in the late 1600s by the dutch scientist antonie van leeuwenhoek, who used fine grains of sand as a gauge to determine the size of human erythrocytes.
