forward facing lens

The forward facing automotive camera is a rapidly developing application.  The first systems were relegated to simple functions such as intelligent headlamp control (IHC), lane departure warning (LDW), or rain sensing.  Succeeding generations of forward facing cameras may incorporate multiple advanced functions such as: adaptive cruise control (ACC), forward collision warning (FCW), traffic sign recognition (TSR), pedestrian detection, obstacle detection and night vision.  These demanding applications require spiraling improvements in image processing, sensors and lenses. Sunex is pleased to be at the fore front of lens technology for forward facing camera systems. 

Compared to a rear vision lens the optical performance requirements for a forward facing lens are completely different but no less challenging.  A typical optical performance requires high resolution, low F-number, low distortion and minimal package size.  In addition, since the next generation forward facing cameras will use high- or wide dynamic range (HDR or WDR) sensors, special attention must be paid to veiling glare and stray light effects.  Sunex has developed proprietary design, simulation capability, coating, test and process tools that help to address these critical issues. Visit our technology page for more information on Sunex HDR Optimized lenses.

Below are several lenses specifically designed for forward facing automotive cameras that represent the state of the art.  These lenses are also applicable to critical applications where high-dynamic images are important such as security and surveillance in outdoor environment. The off-the-shelf solutions you see below are often a good starting point for a custom OEM solution.  If you cannot find the product that exactly meets your requirements, please contact us.
