Defects in preform can be easily detected by using this equipment. When a preform is held parallel to viewing field colour pattern is seen known as isochromatic fringe. This indicates magnitude of the stresses introduced during moulding process. When a preform is held 45 deg to viewing field a coloured pattern known as isoclinic is seen, this indicates direction of stresses.
