Display & LiDAR Cover Screens

LiDAR, or “light detection and ranging“, is an imaging method which focuses a pulsed laser at an object and measures the time it takes for its backscattered light to return to the sensor. 

LiDAR is indispensable to Advanced Driving Assistance Systems (ADAS) in autonomous vehicles for real-time mapping of traffic and road objects. 

When backscattered laser light returns to the sensor, some amount will be reflected by the cover glass (also called radome) before it reaches the detector. It is therefore crucial to minimize the amount of reflected light with the use of anti-reflective (AR) coatings to optimize the safety and performance of the vehicle. 

AGC's comprehensive range of thin-film coating equipment and solutions, including anti-reflective (AR) coatings and protective coatings, optimizes LiDAR system performance in harsh environments. AR coatings reduce surface reflection and increase the amount of light that reaches the sensor, while protective coatings can help to shield the sensor from rain, debris, and other environmental factors that could compromise its performance. By offering a complete range of coating solutions, AGC Plasma Technology Solutions supports LiDAR system manufacturers to optimize LiDAR system performance and ensure that they are well-protected in challenging operating conditions. Our expertise in PVD equipment design and optical coatings enables us to provide high-quality solutions that meet the demanding requirements of LiDAR applications.

AGC Plasma Technology Solutions provides coating solutions that address specific environmental requirements of LiDAR cover glass (radome). LiDAR systems are often used in harsh outdoor environments exposed to rain, wind, sand, and dust. It is therefore essential that coatings on the cover glass provide superior weather resistance and durability over an extended time. AGC's coating solutions, which integrate a protective top-coating into the stack, ensure that the cover glass is well-protected against environmental factors that could compromise the safety and performance of the LiDAR system. With AGC coating technology, customers can have confidence that their LiDAR systems will continue to function safely and optimally, even under the most challenging conditions.

Most autonomous driving LiDAR systems utilize lasers with near-infrared (NIR) wavelengths, typically at 905 nm, 1064 nm, 1310 nm, or 1550 nm. AGC Plasma Technology Solutions developed interferential coating stacks to minimize reflection at these wavelengths.
