Calibration
Procedure
Both the stage micrometer and eyepiece reticle should be graduated in the
same system (Metric or English). It is easiest to find the number of times
an object is magnified by the objective and the field lens of the given
eyepiece when focused in the plane of the eyepiece reticle.
VALUE ON EYEPIECE RETICLE / VALUE ON STAGE MICROMETER = MAGNIFICATION
FACTOR
Example: An object measures 3.4mm on the eyepiece reticle and 0.34mm on
the stage micrometer. The magnification factor is 3.4 divided by 0.34 which
equals 10.0.
Therefore:
SIZE OF OBJECT IN THE EYEPIECE / MAGNIFICATION FACTOR = ACTUAL SIZE OF OBJECT
Example: If an object measures 1.6mm on the eyepiece reticle, its actual
size is 1.6 divided by 10.0 or 0.16mm. |
