Industrial Applications

1. High-Speed Pharmaceutical Vial Particulate Inspection

A machine vision setup utilizing the Kowa LM50XC lens to inspect moving glass vials for liquid particulates, label alignment, and micro-cracks on high-throughput pharmaceutical packaging lines.

Problem Solved

Fast-moving conveyors require ultra-short camera exposure times to prevent motion blur, which typically starves the sensor of light. Furthermore, viewing curved glass surfaces at wide angles causes parallax distortion. The fast aperture range starting at F/1.8 maximizes light intake for high-speed shutters, while the 50.0 mm focal length and narrow angle of view (20.6° x 15.7°) flatten the perspective to ensure accurate Optical Character Recognition (OCR) and defect detection on curved edges.

2. Automated Optical Inspection (AOI) for Micro-BGA Solder Joints

Integration of the Kowa lens into a robotic Automated Optical Inspection (AOI) cell. With its short working distance and high resolving power, it is perfectly suited to ensure very small parts are visible in precision industrial applications.

Problem Solved

Detecting sub-millimeter solder bridging or missing BGA connections requires immense optical resolving power, yet the vision system must remain physically distant to avoid colliding with moving assembly probes. The minimal object distance (M.O.D.) of 0.30 m provides the necessary physical gantry clearance, while the 3.45 µm minimal pixel pitch allows the 12.00 MP sensor to resolve microscopic component defects without aliasing.

3. OLED/Micro-LED Flat Panel Display Sub-Pixel Defect Detection

An inline optical test station utilizing large-format industrial line-scan or matrix cameras paired with the LM50XC lens to identify dead, stuck, or uneven sub-pixels across large digital display panels.

Problem Solved

Standard optical lenses suffer from severe vignetting or edge softness when used with large format industrial sensors, causing false-positive defect detections during panel brightness and uniformity testing. The maximal image circle of 4/3" ensures pristine edge-to-edge illumination across large sensors, while the robust C-mount interface provides secure, vibration-resistant mounting for rigorous 12.00 MP quality control.
