Strainoptics PS-100-SF
Note: These instructions are not meant to replace the full Strainoptics PS-100-SF instruction manual
supplied with your polarimeter. If you are not yet familiar with the initial setup, general operation, and
maintenance requirements of your instrument, or if questions arise, please refer to the complete manual
for further details. Before proceeding, we recommend that you become familiar with the names of the
various instrument components as shown in the illustration below.
In order to calculate stress in your material, you must first know its thickness in millimeters
and its material stress constant in Brewsters. In order to use the Tardy Method of analyzer
rotation, you must first know or be able to determine the direction of principal stresses at the
point of interest. See the PS-100 instruction manual for further details.
1. Configure the instrument for CIRCULAR polarization as follows:
a. Verify that the Polarizer plate (not shown) is installed with the nameplate "CIRCULAR" facing
up.
b. Loosen the Analyzer Scale Lock (L). Using the Rotation Handle (H), rotate the Analyzer Scale
(S) until the number "1" on the Analyzer Scale lines up with the Analyzer Scale Lock (L). The
Reference Mark (R) should be adjacent to the number "-45" on the Protractor Scale (PS).
Tighten the Analyzer Scale Lock.
c. Using the Analyzer Knobs (K), rotate the Analyzer (A) so that the Index Marks (I) are aligned
with the number "1" and "0" on the Analyzer Scale.
d. Move the P-C handle (PC) to the "C" position (under the Rotation Handle).
2. Turn on the illuminator. When looking through the Analyzer, the field will be dark. Place the sample to
be measured on the Polarizer plate.

Identify the direction of the principal stress being measured. If unknown, refer to the PS-100-SF instruction manual to determine direction, or use the SENARMONT method of analyzer rotation instead.
