Fingerprint Scanner Lens
The fingerprint-scanner lens is dedicated to fingerprint acquisition, working with a CMOS sensor to capture fine texture. An optimized design provides high resolution, low distortion and moderate depth of field to resolve ridges, valleys and sweat pores. Specialized antireflection coatings reduce interference from plastic and glass reflections. A small structure and compact interface fit confined fingerprint modules. Good ambient-light rejection and consistent imaging meet matching-algorithm requirements in live-fingerprint capture equipment.
