Explore our precision telecentric lens series — purpose-built for high-accuracy dimensional inspection and gauging of automotive components on the production line.
The global automotive vision inspection market is undergoing rapid transformation. Bi telecentric lenses are at the heart of this revolution — enabling non-contact, high-throughput dimensional verification that traditional gauges simply cannot match.
Unlike conventional lenses, bi telecentric optical systems maintain a constant magnification regardless of object distance — a critical property for dimensional measurement of complex, three-dimensional automotive parts.
Both object-side and image-side telecentricity eliminate perspective distortion entirely, ensuring that edges of a part are measured at the same magnification regardless of height variation — essential for stepped or machined automotive components.
Even if a part shifts slightly in the Z-axis during conveyor transport, the bi telecentric design maintains dimensional accuracy. This is impossible with standard entocentric lenses and is the primary reason automotive OEMs specify telecentric optics.
Bi telecentric lenses pair naturally with coaxial and telecentric illumination sources, producing shadow-free, high-contrast silhouette images ideal for edge detection and precise dimensional gauging of metal parts, gears, and connectors.
Modern bi telecentric lenses support high-resolution sensors and fast frame rates, enabling 100% inline inspection at production speeds exceeding 200 parts per minute — replacing slow offline CMM sampling with real-time quality control.
Engineered with precision-machined aluminum housings, anti-vibration mounts, and sealed optical elements, automotive-grade telecentric lenses maintain calibration stability across temperature and vibration conditions typical of production floors.
The geometric consistency of bi telecentric imaging provides ideal training data for AI-based defect classification models. Uniform magnification and lighting reduce preprocessing complexity and dramatically improve model accuracy and generalization.
Bi telecentric lenses serve a wide spectrum of critical measurement tasks across every major domain of automotive parts manufacturing and assembly verification.
Bi telecentric systems measure tooth pitch, root diameter, and involute profile of transmission gears with sub-micron repeatability. Any deviation from tolerance triggers immediate rejection before assembly, preventing costly gearbox failures downstream.
High-pin-count automotive connectors require precise pitch and height verification. Bi telecentric lenses capture the complete pin array in a single frame, detecting bent, missing, or misaligned pins at line speed — critical for EV battery management systems.
Caliper bores, rotor thickness, and suspension arm geometry are measured inline using bi telecentric vision systems. The parallax-free imaging ensures that measurement results are independent of part placement variation on the fixture.
Thread pitch, major/minor diameter, and head geometry of bolts and screws are verified at high throughput. Bi telecentric optics resolve thread profiles clearly, enabling reliable pass/fail decisions for safety-critical fasteners in chassis and powertrain assemblies.
As electric vehicles dominate the market, precise cell height, terminal position, and module alignment verification become paramount. Bi telecentric lenses provide the dimensional accuracy required for safe and reliable battery pack assembly.
Body panel stampings, brackets, and structural reinforcements are gauged for hole position, edge straightness, and flange angle using wide-field bi telecentric systems — enabling 100% inspection of high-volume press shop output.
The convergence of Industry 4.0, electrification, and AI-driven quality systems is reshaping how telecentric lens technology is specified, deployed, and integrated in automotive plants worldwide.
