100% optical inspection of contact lenses, ocular/intraocular lenses up to industrial microlenses.
The general optical quality control of lenses aims at inspections of lens shape, lens character, surface scratches, irregularities, discolourations or other deviations. These are not only functionally relevant but also aesthetic defect checks.
Compar has a wide range of complete solutions for optical quality inspection of contact lenses, ocular/intraocular lenses and industrial microlenses. These solutions are used in almost all production steps. From lens shape inspection, completeness control, lens character inspection, packaging integrity to label verification on primary and secondary packaging components.
Coloured, patterned, transparent, reflective and mirrored surfaces can be inspected with industrial image processing. Compar AG has an extensive collection of smart surface algorithms for 2D and 3D recognition, summarised as a surface/cosmetic inspection module, which is a main component of the integrated image processing software VISIONexpert®. Based on the customer's requirements, the appropriate algorithms for the solution are determined, tested and finally implemented.
Defect free lenses
Smart inspection algorithms detect the smallest defects. These include soiling, irregularities, discolouration or other deviations from the target.
Ease of use
Fast and simple production-accompanying training routines for new products. Short changeover times between different products.
Degrees of freedom and flexibility
Optical defect detection from combinations of different methods and specific illumination techniques. Depending on the quality control requirements, "Deep Learning" algorithms are also used in addition to the classic inspection method.
