How Do You Read A Slide Micrometer?
A slide micrometer measures very small things. Only visible through a microscope, the slide micrometer is a tiny “tape measure” of sorts printed onto a microscope slide. It has graduated intervals of .01 mm. Another use of a slide micrometer is to calibrate a micrometer eyepiece. Place the slide micrometer on the stage of the microscope and observe it through the eyepiece. Focus on the lines of the micrometer using the low-power lens. Count the lines to read it. Most slide micrometers have graduated .01 millimeter increments. This means each line equals .01 mm and 10 lines equal .10 mm. One hundred lines equal 1 mm.
