Solid-State Optical Mouse Lens
Data Sheet
Description
Ordering Information
The ADNS-3120-001 Solid-State Optical Mouse Lens is
designed for use with Avago Technologies Optical Mouse
Sensors ADNS-3040 and the illumination subsystem
provided by the ADNS-2220 LED Assembly Clip and the
HLMP-EG3E-xxxxx LED. Together with the LED, ADNS3120-001 provides 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.
