305mm x 305mm viewing area to accommodate larger preforms.
Low profile light enclosure provides a comfortable work height for operator.
24 watt LED panel giving a bright flicker free light field.
High quality polarizer’s with clear cast acrylic protection.
Many of the defects found in PET container preforms can be detected using the QCI-1-305.
Preforms viewed in polarized light exhibit a coloured birefringence pattern.
The birefringence is a result of the polymer flow lines (molecular orientational strain) produced during the injection moulding process.
The coloured pattern observed with the preform held at 45 deg to the polarizing axis is known as an isochromatic fringe indicating the amount of birefringence.
When the preform is held parallel to the polarizing axis a black isoclinic fringe can be seen indicating the direction of the molecular orientational strain.
By correctly interpreting these flow patterns many preform defects can be detected.
