Optical Finger Navigation Sensor and Lens

Avago Technologies' Optical Finger Navigation (OFN) Sensor is a compact, precise, fast speed, and highly reliable navigation solution to help enhance overall system performance in mobile phones and much more. The Avago OFN Sensor ADBS-A320 is capable of high-speed motion detection of up to 15 inches per second (ips) and features an on-chip oscillator and integrated LED to minimize external components. With no moving parts, designers can create a highly reliable device with little or no maintenance. Avago Technologies' Optical Finger Navigation (OFN) Sensor does not require precision optical alignment to help with high-volume assembly. The small form factor ( SFF ) 6mm x 6mm x 1.38mm enables space savings and profile reduction. The Avago OFN Sensor features intelligent power management to extend operating hours and battery life.

The ADBL-A321 Optical Finger Navigation Lens is the optical component necessary for the proper operation of the sensor, providing direct illumination and optical imaging.
