Automotive In-Cabin Lens Portfolio
This segment’s most prominent camera applications are Driver Monitoring (DMS) and Occupant Monitoring Systems (OMS). DMS is already delivering on face tracking and driver authentication, and with health and vital sign monitoring, the span of possible use cases is just increasing; in some cases now made mandatory by regulators for all new car models. OMS in turn, will enable many convenience features but also promises breakthroughs in child safety and general passenger health monitoring.
In the attempt to consolidate the number of cameras in the cabin while at the same time delivering on functionality mandated by regulators and expanding additional functionality for all onboard occupants, the class of DOMS cameras has been introduced. There are multiple approaches to selecting the ideal lens for a DOMS camera, and the solution space includes high-resolution SuperFisheye lenses as well as lenses with a FOVEA distortion profile that is aligned off-center. No matter what distortion characteristic is selected, all these solutions require extensive design, material, and manufacturing know-how and expertise to deliver on RGBIR-optimized lenses that offer high performance over a broad wavelength spectrum.

Key Technologies
Industry-leading 5MP RGBIR Designs
We are leveraging best-in-class design expertise and are constantly driving process improvements and manufacturing innovation for our global customer base to push the boundaries of what is possible. Our optical and mechanical engineering teams apply their proven engineering know-how to create new products and novel solutions to support your project goals. From Design To Cost (DTC), Design for Manufacturing (DFM), and Design for Reliability (DFR), we always have the full product development cycle and your specific business case in mind.
RGBIR lenses are optimized for operation in both daylight and low-light conditions. Such products require specialized design considerations, broadband AR coatings (BBAR) with low reflectivity (R%), dual-bandpass filter with high transmissivity (T%) in the VIS and IR bands, and specific manufacturing techniques to provide the best possible image quality. If done right, an RGBIR lens can significantly improve focus, brightness, and resolution over conventional lenses.
The enhanced infrared sensitivity of RGBIR lenses is often paired with a dedicated infrared illumination source, enabling combined Driver Monitoring (DMS) and Occupant Monitoring (OMS) in a single system (DOMS) for simultaneous gaze tracking, gesture recognition, and VIS streaming.
Multiple HFOVs and Distortion profiles for DMS, OMS, and DOMS
In automotive In-Cabin applications for DMS, OMS, and combined as DOMS, having the right distortion profile plays a crucial role in enhancing safety and precision. These specialized lenses are engineered to minimize image distortion and optimize visual clarity across varying fields of view; from very narrow to wide-angle cameras.
Advanced Mechanical Designs
Sunex’s renowned excellence in Optical Design is complemented by its extensive experience in optomechanical design. From threaded aluminum barrels, to barrels with glue flange for active alignment, to the more advanced solutions featuring aluminum or plastic unibodies. We always see the optical path as one component of a larger system that, together, needs to be optimized.
Supporting Services
Reliability and Environmental Testing
Often, it is not the challenge to create a design “that works” but to find a solution that can scale to mass production (DFM), meets required price targets (DTC), and delivers on performance and quality (DFR). Our deep design and manufacturing experience comes from servicing some of the most demanding markets and applications, and combined with consistent quality and global on-time delivery, Sunex is the preferred partner for many.
“Scaling” as a lens design tool
“Scaling’ refers to a method where a known lens design is proportionally enlarged or reduced geometrically to meet a different image size requirement.
