ADBL-A321 Optical Finger Navigation Lens Data Sheet Description The ADBL-A321 Optical Finger Navigation Lens is designed for use with PixArt Imaging 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. Figure 1.

ADBL-A321 Optical Finger Navigation Lens Mounting Instructions for the ADBL-A321 Lens to the Base Plate An IGES format drawing file with design specifications for mouse base plate features is available. These features are useful in maintaining proper positioning and alignment of the ADBL-A321 when used with the PixArt Imaging Optical Sensor. This file can be obtained by contacting your local PixArt Imaging sales representative. Handling Instructions for the ADBL-A321 Lens Several careful handling instructions must be observed when handling lens. They are listed below:1. Pick up the lens at the lens side using a pair of tweezers from the tray. See figure 2. 2. Do not touch the optical surfaces as highlighted in red of the lens. See figure 3a, 3b. 3. It is recommended to use clean dry air CDA air blow system to clean the lens before assembly to minimize particle contamination. Figure 3a. Lens bottom view Figure 2. Handling lens Figure 3b.
