Abstract

The need to detect defects in optical glass during IQC, post cleaning, post coating and final QC has become of paramount importance. Optical glass is very high value-added and must be defect-free. Throughout the industry, legions of inspectors perform manual inspection. Manual inspection adds significant cost, reduces yield and becomes the production bottleneck. In-line 100% automatic defect detection can augment or replace manual inspection and delivers a host of benefits including increased throughput, improved yield, scrap reduction, reduced labor cost and maximum customer satisfaction. Solid-State Laser Reflection (SSLR) technology has been successfully applied to this challenge; defect detection to 1µm has been achieved.
