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 competing optical sensors to protect the delicate sensor components or to improve contact with the skin. Such coatings may be vulnerable to scratches, corrosion, and wear and tear 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 or lenses.
