1. Semiconductor & High-Density PCB Defect Metrology
In electronics manufacturing, this application integrates the Kowa lens into automated optical inspection (AOI) machines to scrutinize bare wafers and high-density printed circuit boards. The lens is paired with a large 1.1-inch high-resolution sensor to capture extreme close-up images of microscopic wire bonds and solder joints.
Problem SolvedDetecting sub-micron anomalies such as micro-cracks or solder bridging requires immense optical clarity. The incredibly short 0.15 m Minimal Object Distance (M.O.D.) combined with the 75.0 mm telephoto focal length enables massive macro magnification. Furthermore, the 2.50 µm minimal pixel pitch and 24.00 MP resolution ensure that ultra-fine trace defects are resolved perfectly without optical aberration.

2. Remote High-Heat Metal Casting Inspection
Used in foundry automation and metallurgy, this lens is paired with a heavy-duty industrial camera enclosure to monitor red-hot metal castings and welding seams. The system captures high-fidelity surface imagery to detect porosity and hairline cooling cracks from a secure, remote location.
Problem SolvedIndustrial cameras placed too close to molten or highly heated materials suffer from immediate thermal degradation. The 75.0 mm focal length and extremely narrow 8.0 degrees by 10.7 degrees angle of view allow the inspection system to be mounted at a long, safe standoff distance while still magnifying critical surface details. The aperture range of F2.5-16 can be manually stopped down to compensate for the intense radiant light emitted by the hot metal.

3. Intelligent Traffic Systems (ITS) Overhead LPR
Deployed in highway tolling and intelligent traffic monitoring systems, the lens is used in gantry-mounted vision setups to capture front and rear vehicle license plates across multiple high-speed lanes. It provides necessary telephoto capabilities to read alphanumeric characters accurately.
Problem SolvedCapturing fast-moving targets from a high, distant gantry often results in blurred or digitally pixelated images upon cropping. The 75.0 mm focal length optically bridges the physical distance, while the massive 1.1-inch maximal image circle and 24.00 MP resolution permit the LPR software to crop into specific highway lanes with zero loss of required pixel density. The F2.5 maximum aperture ensures fast shutter speeds can be maintained in varying outdoor light.
