MITSUMI
Solid Optical Fingerprint Sensor
SEF-A1F1
OUTLINE
An optical sweep-type compact fingerprint
sensor. Eliminates the shortcomings of
conventional optical fingerprint sensors, which
are large and heavy due to use of lenses and
prisms. The interdigital scattered light method
realizes stable, high-accuracy detection at low-
cost with a major reduction in size and weight.
Increased resistance to static and shock make
this technology ideal for inclusion with a variety
of devices.
FEATURES
1. Small size and light weight achieved by molding optical components as one piece.
2. The semiconductor is not exposed, giving excellent durability.
3. Waterproofing improved through use of a flange.
4. The finger scattered light method allows use on wet fingers.
5. The light filter allows use on dry fingers.
6. A signal processing LSI can be provided (supports SPI and parallel I/F).
USES
1. PC units, portable information devices, network terminals
2. IC card readers
3. Security devices
