ADNS-2120-001 Solid-State Optical Mouse Lens Data Sheet Description The ADNS-2120-001 Solid-State Optical Mouse Lens is designed for use with PixArt Optical Mouse Sensors and the illumination subsystem provided by the ADNS-2220-001 LED Assembly Clip and the HLMP-EG3E LED. Together with the LED, the ADNS-2120-001 provide the directed illumination and optical imaging necessary for proper operation of the Optical Mouse Sensor. The lens is a precision molded optical component and should be handled with care to avoid scratching of the optical surfaces.
