When a Preform is held *5 degrees to viewing field, a coloured pattern known as ISOCLINIC is seen, this indicates direction of stresses. The advantage of our meter are Crystallinity is readily identified, Not only can the Molecular birefrigetent flow lines ( fringes ) be seen in colour but the black ISOCLINIC lines are visible when the Preform axis are parallel to the molecular orientation strains, A special and removable stage is provided to rapidly obtain the correct alignments of the Preforms when viewing for observations of the fringes the Preforms are aligned at *5 degrees to the polarising axis and at 0 degrees to view the black ISOCLINICs. The stage allows for the rotation of the Preform whilst viewing. With higher end model a Preform of *0 litres jar can also be checked with the length of Preform up to *4 inches (**0 mm).
