Abstract
An optical navigation apparatus and method for making the apparatus uses a light source and a sensor having an imaging array mounted on a leadframe and encapsulated in an optically transparent body structure. The optically transparent body structure is configured to include a prism-like feature to internally reflect light from the light source toward a target surface and an imaging lens feature to optically manipulate the light reflected from the target surface onto the imaging array of the sensor.
