LiDAR Sensors Adhesives
LiDAR (light detection and ranging) sensors have the potential to be essential components in autonomous vehicles, robots, and drones due to their 200+ meter detection range and insensitivity to hazardous conditions (fog, rain, snow, darkness). They also can be incorporated in current systems for adaptive cruise control (ACC), collision avoidance, traffic sign recognition, blind-spot detection, and lane departure warning.
With anticipation of the exciting potential of LiDAR sensors as the critical components in the safety of autonomous driving, ACW provides a full range of dual-cure adhesives for many assembly tasks including lens bonding, laser diode assembly, and packaging. ACW adhesives provide a variety of features including light filtering (400 to 1600 nm), thermal conductivity, active alignment, and hermetic sealing. In the table below, all of the adhesives are one-part, 100% epoxy resins with the following features.
A, Dual-Cure (UV and/or heat); B Lens to components; C Active alignment; D Packaging; E Thermal conductive; F Hermetic sealing; G Die attach; H Filters Near IR light; I High UV depth of cure.

*Viscosity at 25 °C; for thixotropic resins, the viscosity was measured at a 10 s-1 shear rate.
**Thixotropic Index = η at shear 1 s-1 / η at shear 10 s-1.
