The SecuGen sensor is well-known for its ruggedness and
solid engineering, as well as its virtually indestructible
sensor prism, which is made of a very hard quartz-like material
that resists scratches, stress and corrosion.
From the sensor surface to the internal lens and electronic
components, all aspects of the SecuGen sensor were carefully
designed and redesigned to work reliably and consistently
for even the most demanding applications.
SecuGen sensors were tested under extreme conditions and
have been proven to perform in high-traffic, outdoor and
other rough environments. They resist exposure to:
- Subfreezing, arid, and tropical climates
- Electrostatic discharge (ESD)
- Impact, vibration, and shock
- Scratches to sensor prism even from sharp objects
- Contaminants and corrosives such as sweat, dirt, oil
and cleaning agents
SecuGen sensors do not use any coatings or membranes, which are required by many semiconductor-based sensors and competitive optical sensors in the market in order to protect the delicate sensor components or to improve contact with the skin. Such coatings may be vulnerable to scratches and corrosion that can degrade the performance of the sensor over time and cause unexpected replacement or repair costs in the long run.
Additionally, the optic parts are tightly assembled so
that if the sensors are ever dropped, there is no need for
re-calibration, which is often necessary for smaller form-factor
optical sensors that use an intricate arrangement of mirrors
