Advanced Driver Assistance Systems (ADAS) demand new levels of performance and reliability from optical sensors, particularly where autonomous functionality is desired. These systems must maintain the ability to recognise critical situations whatever the driving conditions, and remain unaffected by stray light that could even momentarily blind sensors with potentially devastating consequences.

Vantablack VBx2.3 is an economical, nanomaterial free, ultra-low fogging black paint that minimises or eliminates the effects of stray light in ADAS applications such as camera shielding and Head-Up-Displays. VBx2.3’s design ensures performance is maintained even under the most demanding conditions. VBx2.3’s advanced, nanomaterial-free formulation ensures cost-effective coating using industry-standard spray equipment.

Cameras

In modern vehicles, cameras have taken over functions such as distance metering and maintenance, object recognition, lane-departure warning and traffic sign recognition amongst many others. These optical systems are frequently subjected to unfavourable lighting conditions, resulting in unwanted stray-light. This stray light degrades system performance, causing veiling, glare and artefacts that are familiar to many photographers. The trend towards wider field of view cameras for enhanced functionality further increases the challenge posed by stray-light and demands the use of superior stray-light management technologies (SLMT)™ to ensure captured images reflect reality. Vantablack VBx2.3 applied to camera glare shields minimises or eliminates these stray-light effects, ensuring the optical system remains compliant with critical automotive safety requirements.

Head-Up-Displays coated with Vantablack VBx2.3 show improved contrast ratio and far lower levels of windshield artifacts in all lighting conditions when compared against traditional black absorber paints and flocking.

Traditional black paints and flocks tend to fog (outgas) at the increased temperatures found in modern HUDs. This leads to sensitive optics being degraded by condensed fogged material over the life of the unit. VBx2.3 delivers highly efficient stray light absorption without fogging or degrading HUD optical systems.

Head-Up-Display

To enhance safety, virtual images projected by Head-up Displays (HUDs) must exhibit high Perceived Quality (PQ) whatever the lighting conditions. Eye strain caused by inadequate contrast or moving stray light artefacts on the car windscreen must be eliminated to prevent the driver becoming tired, distracted or having the view of the road obscured. Vantablack VBx2.3 applied to projection paths and internal baffles achieves these objectives without requiring any changes to the design of the device.

Traditional solutions such as textured baffles, paints and flocks either do not satisfy the optical requirements for next generation ADAS, are too costly to process, or suffer from long-term fogging that causes unacceptable image-degradation over the life of the car. Vantablack VBx2.3 provides uniform, exceptional optical performance, regardless of the position and intensity of unwanted light sources, and delivers a cost-optimised, superior coating solution designed to outlast the vehicle.
