Telecentric lens solves visual problems - inner hole defect detection

Traditional optical systems face significant limitations in quality control and defect detection, often leading to increased labor and material costs. With years of experience in visual inspection, machine vision systems are designed to offer specialized imaging and inspection solutions, progressively replacing traditional manual methods. These advanced systems reduce labor costs and meet high-precision defect detection requirements. Here's an in-depth look at how double telecentric lenses can be used to overcome the limitations of traditional optical systems in defect detection, with a focus on internal aperture inspections:

Double Telecentric Lenses for Internal Aperture Defect Detection

Application Scenario When detecting internal aperture defects, such as in ceramic filter cores, the task is to identify whether the core is damaged, obstructed, or clogged due to impurities or defects. These defects can be challenging to detect because traditional imaging systems often struggle with alignment and parallax issues.

Challenges Ceramic filter cores can range in height from 50 to 80 mm, with very small apertures on the cross-section. Traditional optical systems face parallax issues, where the light passing through these apertures is obstructed by the non-reflective inner walls. This makes it difficult to accurately assess whether the apertures are unobstructed.

Solution A double telecentric vertical inspection platform, designed to capture a full projection without longitudinal parallax, solves this problem. The light passes through the ceramic filter core's internal apertures without interference from parallax, allowing for accurate detection of defects and impurities. This approach perfectly addresses the issues encountered with traditional optical systems.
