+
+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.
