HOW TO USE THE POINTMASTER
®
EYEPIECE RETICLE
Swift's patented POINTMASTER® eyepiece reticle, which is installed in
the eyepiece of the microscope, enables the user to easily measure the
size of the specimen
I. The numbers on the chart indicate the actual size of the
POINTMASTER® scale in millimeters. For example, the length is
1.0mm from the top of the arrow to the bottom; the total length of
the scale is 8.0mm, etc. The thickness of all the horizontal lines is
0.01mm.
2. To obtain the actual physical size of a specimen, divide the
POINTMASTER® scale readings by the magnification of the objective
lens that is in use. Divide the readings by 10 if the 10X objective is
being used, 40 if the 40XRD objective is in use, or 100 if of 100XRD
is in use.
