ADNS-7700 Datasheet, PDF (7/60 Pages) AVAGO TECHNOLOGIES LIMITED – One chip USB LaserStream Mouse Sensors Single 5.0 volts power supply

As shown in Figure 5, the components self align as they
are mounted onto defined features on the base plate.
The ADNS-7700 sensor is designed for mounting on a
through-hole PCB, looking down. The guide holes in the
sensor package mates and self-aligns with the guide posts
in the ADNS-6180-001 or ADNS-6180-002 lens.
The integrated VCSEL is used for the illumination, provides
a laser diode with a single longitudinal and a single trans-
verse mode. Together with the VCSEL contained in the
sensor package, the ADNS-6180-001 or ADNS-6180-002
lens provides directed illumination and optical imaging
necessary for the operation of the sensor. The lens is a pre-
cision molded optical component and should be handled
with care to avoid scratching and contamination on the
optical surfaces.
3D drawing files in STEP or IGES format for the sensor, lens
and base plate describing the components and base plate
molding features for the lens and PCB alignment is avail-
able.
