+description: |-
+ 2.2 MP NIR enhanced global shutter image sensor designed for 2D and 3D
+ consumer and industrial machine vision applications.
+ Due to its small size, configurability and high sensitivity both
+ in visual as well as NIR, the Mira220 is well suited for 2D and
+ 3D applications, which include Active Stereo Vision,
+ Structured Light Vision for Robotics and AR/VR.
