If applied AI for embedded vision aims to replicate human understanding, then the optical stack plays a significant role in achieving a human-like vision for any camera-based application. Choosing the right lens is a curtail step in system-level optimization and setting a roadmap to achieving desired outcomes. With Sunex as a lens and technology partner, our clients can access specific lens technologies to optimize algorithms, reduce system latencies and power consumption, and enhance imaging performance.
Sunex’s expertise and experience in manipulating distortion profiles to support algorithm-specific requirements have been valued by customers for many years. Our Tailored Distortion™ expertise has often been applied to SuperFisheye™ lenses to correct barrel distortion of large FOV lenses.
Sunex’s FOVEA distortion lenses are designed to mimic human vision. The distortion profile results in a higher pixel density in the center while maintaining a wide field of view, thus optimizing the performance of machine vision algorithms.
Environments with low or changing light are a challenge for any algorithm. Sunex has lens designs that combine very low F/#, high Relative Illumination (RI), high dynamic range (HDR), high MTF across the field, and a broad wavelength spectrum for consistent performance across a variety of scenarios.
Sunex has developed design expertise, process know-how, and nested cleanroom manufacturing facilities to eliminate or minimize optical noise (such as ghosts, flare, starbursts, spurious images) in lenses for high-performance applications.
All graphs are for illustration purposes only. The individual lens performance can be different.
Sensor Module Capabilities
Depending on the need and expertise of our customers, we provide design and manufacturing services for a complete sensor module. We strive to find the best solution for your needs, from designing the schematic, creating the PCB layout, and sourcing all components to building according to your PCB design and parts consignment. At Sunex, we have the in-house expertise and capabilities for lens and sensor board design, manufacturing, and testing to deliver a fully tested sensor module.
Active Alignment Capabilities
To achieve the highest system performance when pairing a high-quality lens with a high-resolution sensor, we recommend that our customers consider an active alignment process. Applying a fully automated 6-axis active alignment in mass production increases yield, shortens cycle times, improves system performance, and lowers part-to-part variance.

Fast Prototyping
We provide prototyping services for complete lens assemblies often as the first step after a new custom design.
Sunex can produce prototypes with short lead times to verify the design before transitioning further on the path to mass production using state-of-the-art fabrication processes for glass and plastic optical elements and all mechanical components.
