    calibrated

  • what is used to calibrate a microscope

    stage micrometer

  • what is a stage micrometer

    a slide with a very accurate scale in micrometers

  • what is an eyepiece graticule

    a disc placed in the eyepiece with 100 divisions

  • scale of eyepiece graticule

    none

  • formula for calculating 1 graticule division

    number of micrometers / number of graticule divisions

  • formula for measurement of a specimen

    graticule divisions x magnification factor

  • definition of magnification factor

    the calibrated measurement of the graticule divisions
