HD Lighting Lens Portfolio

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.

Key Technologies

Optimization for MTF, Color, and Efficiency
The requirements for high-resolution automotive projector lenses are evolving as the adoption of this technology rapidly increases. 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 address the expanding solution space.

Athermalization
The shift of a lens’s focal point over a wide temperature range is a physical phenomenon based on the material-specific expansion and contraction with temperature. A decrease in image quality could be the outcome if the focal point of the lens relative to the sensor’s image plane shifts too much. A fully athermalized system requires selecting appropriate optical and mechanical materials, the right design strategy, and close collaboration with the customer to optimize thermal performance on a system level.

All graphs are for illustration purposes only. The individual lens performance can be different.

Supporting Services

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.

Test & Measuremnet Capabillities
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.
