- The field of view (FOV) is the entire circular image we see when looking into the eyepiece. The diameter of the FOV gets smaller as we increase magnification. It can be measured by using a stage micrometer like a ruler, measuring from edge to edge. Notice that the stage micrometer is 1000 microns (µm) in length, and the field of view under the lowest magnification is 5000 µm. Describe how we measure it?Look for journal articles, news, or features published recently (2017 to 2022) that show the application of spectroscopy in a field of study (such as medicine). Please summarize this technique, highlighting its theories and how it fares with other analysis methods.Which statement(s) describe(s) a microplate reader?A. It is spectrophotometerB.
