Industrial Applications

1. High-Precision Quality Control in Electronics Manufacturing

This lens, with its 12 MP resolution and ability to achieve 140 LP/mm, is ideal for inspecting minute components and solder joints on printed circuit boards (PCBs) or semiconductor wafers. The low distortion ensures accurate measurements across the entire field of view, critical for automated optical inspection (AOI) systems. The 0.1m minimum working distance allows for close-up inspection.

Problem Solved

Ensures the detection of tiny defects, misalignments, or contaminants that are invisible to the naked eye, improving product reliability and reducing waste in high-volume production.

2. Pharmaceutical Packaging and Label Verification

The lens's high resolution and clear image quality, coupled with low distortion, are perfect for verifying alphanumeric codes, barcodes, and intricate graphics on pharmaceutical packaging and labels. It can accurately read expiration dates, lot numbers, and ensure label integrity and placement at high speeds in a production line. The 0.1m minimum object distance is suitable for inspecting small packages.

Problem Solved

Prevents mislabeled or incorrectly packaged pharmaceutical products from reaching the market, ensuring regulatory compliance, patient safety, and brand protection.
