electronic eyepiece micrometer M202E description
The M202E consists of an adjustable 10X eyepiece micrometer with rotary
encoder, a programmable digital display and power supply. It is
added to microscopes to provide fast, convenient and precise
measurements. The rotary encoder gives 2000 counts per revolution
using a high precision 1 mm pitch screw. The range of crosshair travel
of 18 revolutions therefore covers 18 mm within the eyepiece. The actual field of
view or range
on the object will be limited by the initial magnification or field of
view of the objective. The compact digital display has 6 digits and is user
programmable so virtually any scope magnification can be calibrated.
objective magnifications will affect the accuracy of measurement.
The precision of the reading will generally be greater with an objective
of higher magnification because the object will appear larger thus
requiring more travel or turns of the micrometer screw across the object.
However, often times it is easier to measure
with less magnification because the measurement beginning and end points are easier to recognize
and appear sharper and so actual experience with the measurement is the
The following objectives are optionally available for the
