The vast majority of machine vision optical components for today’s vision and inspection automation can be easily accommodated by standard catalog optics.
However, “standard” won’t cut it for machine vision market leaders looking to differentiate, innovate, incorporate AI workflows, and move into use cases like semiconductor inspection that create value and demand a premium.
Machine vision camera system integrators have traditionally relied on commoditized machine vision lenses, including C-mount, F-mount, telecentric, and line-scan lenses, to drive down costs and make automation more approachable in manufacturing. These standard optics are a reliable and readily available starting point, but their one-size-fits-all nature can lead to commoditized performance and limited differentiation.
In next-generation machine camera designs for advanced applications such as semiconductor inspection and biotech applications, specialty optics – including prisms, beam splitters, filters and windows, specialty coatings, and custom assemblies – can deliver new levels of signal-to-noise, increasing accuracy and throughput.
As machine vision camera designers look to differentiate and expand into new performance-driven markets, optical requirements introduce a new set of technical and manufacturing challenges.
Improved signal-to-noise ratio: Especially for machine vision camera systems for low-contrast or high-speed inspection, optical design improvements may call for custom coatings and assembly improvements to increase signal-to-noise ratio.
Field failures: Challenges with yields or high product return rates may call for tighter, repeatable optical tolerances on spherical and aspheric elements to improve consistency of MTF, distortion and focus across production runs.
AI-driven algorithm demands: Even small decentering or tilt errors can degrade algorithm performance in vision systems. Precise alignment and assembly stability can improve the quality and speed of reliable data.
Innovating in machine vision demands multi-disciplinary collaboration from computer science, mechanical engineering, industrial automation, and optical design. Experienced optical manufacturers like LaCroix can review project requirements and apply design for manufacturability (DFM) principles to lower system costs and position designs for efficient scale-up into high-volume production.
Semiconductor optical inspection is one of the fastest-growing opportunities for machine vision companies, as the challenges and mix of semiconductor inspection techniques increase. Many of the camera companies struggle to find a use case for existing standard technology due to the widely varying approaches and demands of semiconductor tool OEMs. These OEMs are typically tight-lipped about their system design, moving fast, stretched for engineering bandwidth, and have rigorous demands on their supply chain.
Success in this market depends on working with an optical partner that offers:
US-based manufacturing for faster iteration, collaboration, and supply continuity
Proven expertise in precision optics and optical assembly capability
Repeatable processes that scale from prototype to high-volume production
Deep capabilities in performance-critical optics, including: aspheres, telecentric lenses, beam expanders & beam splitters, optical filters, prisms and wedges, multi-element objectives, mirrors, and custom AR, SWIR and DUV coatings
