Industrial Applications

1. Automated Optical Inspection (AOI) for High-Density PCBs

Using the IDS-20M12-C7528 lens in an AOI system to inspect microscopic solder joints and SMD components from a safe working distance.

Problem Solved

Detecting micro-cracks and missing solder on densely packed circuit boards while maintaining sufficient standoff distance to avoid interfering with robotic handling equipment. The 75.0 mm focal length and 0.30 m minimal object distance allow remote mounting, while the 20.50 MP resolution and 2.40 µm minimal pixel pitch ensure sub-millimeter defects are clearly captured. Lockable manual focus and iris prevent loss of calibration from factory floor vibrations.

2. Intelligent Traffic Systems (ITS) and Toll Enforcement

Deploying the high-resolution 1.2-inch C-mount lens on highway gantries for Automatic Number Plate Recognition (ANPR) and vehicle classification.

Problem Solved

Capturing clear, distortion-free images of fast-moving vehicles across multiple lanes from a high-altitude gantry. The 75.0 mm focal length provides a narrow 8.9° x 10.3° vertical field of view ideal for distant targeting. The large 1.2-inch maximal image circle and 20.50 MP resolution deliver the high pixel density required for OCR software to accurately read license plates.

3. Pharmaceutical Vial Particulate Inspection

Integrating the lens into a high-speed pharmaceutical packaging line to detect microscopic contaminants and fill-level anomalies in glass vials.

Problem Solved

Identifying critical, microscopic foreign particles inside liquid-filled vials without halting high-speed production. The lens resolves extremely fine details thanks to its 2.40 µm minimal pixel pitch and 20.50 MP optical class. The adjustable F/2.8-22 aperture range allows machine vision engineers to maximize depth of field, ensuring particles at varying depths within the vial remain in focus.
