Pandora – Dimensional inspection of vials

The Vimec Pandora inspection system is designed for dimensional inspection of the bottom of vials:
– Bottom thickness,
– Bottom concavity,

Way of working
The optical probe and the horizontal slide are mounted to
the back of an indexed transport line as can be seen in the image below. The sensor measures the distance to the first reflective surface (outer wall of the vial) and the second reflective surface (inner wall of the vial). Together with abbe-number (approximate measure of the materials
dispersion) and the refractive index of the glass the thickness can be calculated.
