WebSince the high power objective lens provides four times the magnification of the low power objective lens, the field of view for high power is one quarter that of low power: A low power field of view = high power field of view Measurements like this, smaller than 1 mm, are often expressed in micrometres (also called microns, um). WebThe field of view is the circular area that one sees as one looks through the microscope. To determine the diameter of the field of view, place a plastic ruler under the low power (4 x) objective. Focus on the ruler and lay it so it crosses the diameter of the field of view. Record the diameter of the field of view in millimeters in Table 1.

Determine a Field of View for Each Objective Lens

WebThe ruler just doesn't fit between the objective & the stage. No problem. We can use the width of the field of view under low power (which we measure using the steps above) and the relationship between the low & high power magnifications to mathematically calculate the width of the field of view under high power. First of all memorize this : WebHere’s the formula we’ll use to calculate the HPD. LPD x LPM / HPM = HPD After we’ve done that, we can estimate the size of tiny specimens seen at HPM. Let’s work the formula LPD x LPM / HPM = HPD... how do you make torches in terraria
