Polariscope For Glass & Preform

PolariscopeUsing the Polariscope strain viewer, the manufacturer can test the performance and quality of PET preforms. The Polariscope is an optical inspection machine that is used to measure the internal stresses and strains in the glass and various transparent materials like plastics, synthetic resins etc.
Application: Defects caused during moulding process can be easily detected

Operation :A preform is held parallel to viewing field to study a colour pattern known as isochromaticfringe. This indicates magnitude of the stresses introduced during moulding process. And When perform is held 45 deg to viewing field a coloured pattern known as isoclinic is seen, this indicates direction of stresses.

Specifications: Viewing area =
200mm x 140mmDimensions of Unit =250mm x 250mm x 260mm.
Lamp Source = 2 x 9 watts.220 V AC Single Phase / 110 V AC converter can be provided.
A defect chart is provided to understand defects.
