940 nm VCSEL Flood Illuminator Modules
Use for 3D sensing tasks needing a large field of illumination (FOI), like driving monitoring systems (DMS), occupancy monitoring systems (OMS), and gesture recognition.
Housed in a SMT package, these ultra-compact modules can be used to create narrow or wide fields of illumination for a broad range of optical 3D sensing tasks. They are cost-optimized for high-volume production and are based on an AECQ-102-qualified VCSEL.
940 nm VCSEL Flood Illuminator Modules
Get two different FOI options: either 60° x 45° or 110x85° (Batwing Profile). They feature a nanosecond risetime and include a monitor photodiode for closed-loop operation.
