Lighting functions in and around the car play an ever-increasing role in an OEM’s brand recognition and are a signature piece for corporate design consideration. From a purely technical perspective, modern high definition (HD) headlamps are designed for two main applications: Advanced Lighting Functions and Road Projections.
Even with the underlying technologies advancing far beyond what the early trailblazers of automotive headlamps could have envisioned, we still try to optimize for the same goals:
- reduce glare
- increase efficiency and range
- make driving safer
Sunex’s design, engineering, and manufacturing know-how are well known in the automotive industry. Our consistent quality and on-time delivery made us a preferred supplier for imaging optics for leading Tier1s and OEMs for over a decade. Building on that history and reputation, we successfully advance the new high-resolution automotive headlamps segment with our customers and partners.
The requirements for high-resolution automotive projector lenses are changing as the adoption of this technology is rapidly increasing. Besides the mechanical boundaries and the need to satisfy OEM styling guidelines, we typically see MTF, efficiency, and color aberrations as crucial performance differentiators. Sunex has developed extensive design experience, engineering capabilities, and manufacturing process know-how that addresses the expanding solution space.

Fast Prototyping
We provide prototyping services for complete lens assemblies often as the first step after a new custom design. In automotive headlamps, the series production barrel design is often part of the prototyping efforts. It defines the headlamp module’s critical interface to the vehicle, making it as important as the optical system itself. 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.
Test & Measurement Capabilities
Sunex has expanded the existing design, test, and measurement capabilities to account for the specific needs of projection optics and our automotive headlamp customers. In-house equipment includes test systems for the characterization of large-format projection optics, a goniophotometer lab with industry-standard analysis software, and VDA19.1 test equipment.
