What is a difference between a stage micrometer and an ocular micrometer?

A stage micrometer is simply a microscope slide with a scale etched on the surface. A typical micrometer scale is 2 mm long and at least part of it should be etched with divisions of 0.01 mm (10 µm). Then one ocular division (smallest increment on the scale) = 10 µm at 100 power.Click to see full answer. Keeping this in view, what is stage micrometer?A stage micrometer is the term typically referring to a slide (1″ x 3″ microscope) that comes with a scale on its surface. The sides are mounted with a reticle scale that is used for calibrating the reticles of the eyepiece as well as the objective powers.Furthermore, how do you calibrate an ocular micrometer using a stage micrometer? To achieve the calibrated measurement of the sample, multiply the measured value of the sample by the labeled magnification of the objective lens divided by the actual magnification ratio. An ocular micrometer is a glass disk with ruled scale on the surface which is etched in chromium. Beside above, how do you use an ocular micrometer? Procedure. Place a stage micrometer on the microscope stage, and using the lowest magnification (4X), focus on the grid of the stage micrometer. Rotate the ocular micrometer by turning the appropriate eyepiece. Move the stage until you superimpose the lines of the ocular micrometer upon those of the stage micrometer.What is the purpose of calibrating an ocular micrometer with a stage micrometer?The stage micrometer is used to calibrate an eyepiece reticle when making measurements with a microscope. Eyepiece Reticle (or reticule) -a small piece of glass with a ruler etched into it that fits into a microscope eyepiece. This ruler is used to make measurements of objects viewed through the microscope.
