ADBL-A321 Optical Finger Navigation Lens Data Sheet The ADBL-A321 Optical Finger Navigation Lens is designed for use with Avago Technologies ADBS-A320 Optical Finger Navigation sensor. The ADBL-A321 lens provides the direct illumination and optical imaging necessary for proper operation of the sensor. ADBL-A321 lens is a precision molded optical component and should be handled with care to avoid scratching of the optical surfaces. The lens material is polycarbonate. Cyanoacrylate based adhesives should not be used as they will cause lens material deformation. Lens should not be subjected to temperatures higher than 85°C for 30minutes during assembly. Lens can be operated in a temperature range from -20°C to 80°C.
