Cognex Corporation builds the In-Sight 1750 as a dedicated reader for tracking wafers and panels through semiconductor production lines, extending an In-Sight lineup that also includes the 1740, 2800, and 3800 series. The compact, self-contained unit shares mounting points and form factor with the In-Sight 1740 series, letting fabs swap in the newer reader without retooling a line, and existing 1740 jobs can be converted directly onto the 1750 to cut setup time.
The reader's job is narrow but critical: identify individual wafers as they move through processing so a single mix-up doesn't cascade into a costly batch error. Cognex says the 1750 delivers 100 percent traceability by reading ID marks even after processing has degraded them, marks that grow difficult for both people and standard machine vision to parse. For an engineer running a fab line, that gap between a mark that's technically present and one that actually gets read at production speed is where unplanned stops and scrapped lots tend to originate.
To close that gap, the 1750 pairs a 2MP image sensor with a 38 mm wide field of view, wider coverage than earlier readers, and adds multi-mode illumination that produces both bright field and dark field images. Enhanced RGB lighting improves contrast on reflective or transparent substrates, including silicon, gallium nitride, silicon carbide, sapphire, and glass, materials Cognex says routinely confuse generic lighting setups. On the software side, the reader combines Edge AI optical character recognition with Cognex's rule-based font and code reading, algorithms the company says draw on more than 20 years of semiconductor deployments. An AI autotune function adjusts lighting and image filters in real time as marks vary between wafers and lots, then saves successful settings automatically instead of requiring manual recalibration.
Cognex packages that adaptability as Adaptive Read Resilience, meant to keep read results consistent and auditable without operator intervention when mark quality drifts. The company positions the 1750 alongside application work on wafer notch orientation detection and probe mark inspection and classification, framing the reader as one piece of a broader push into front-end and back-end semiconductor vision tasks rather than a standalone product.
