Functional Description
The CYONS1001L is a two piece kit containing:
1. An IC package (with 2 kV ESD) that integrates:
a. Laser Detector analog and digital circuitry
b. VCSEL
c. Optical aperture
2. A molded plastic piece containing a lens for collimation of
the VCSEL beam and for imaging of the light scattered from
the tracking surface onto the sensor portion of the laser
detector. The molded optic has features for registration to
the package and attachment to the PC board.
