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 lowcost
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

OPTOOL-DSX的特性
OPTOOL-DSX是透明無色、無味的液體。
用OPTOOL DSX處理過的表面擁有以下主要特性
1、超薄膜塗層，DSX防污層約10nm
2、不損傷底層的表面硬度及光學特性等。
3、防污性極佳優良的光滑性
各種污垢(例如指紋)難以附著,同時具有優良的擦拭性。即使用面紙等擦拭污垢,表面也不留痕跡。
