Optical Security for Cryptography & Authentication

Tamper protection and secure data transmission are essential in modern security systems. colorPol® polarizers are used in quantum cryptography (QKD), counterfeit-proof documents, and biometric systems.

  • Secure photon transmission for tap-proof networks
  • Identification and verification of security features on banknotes and identification documents
  • Enhanced efficiency in 3D facial recognition and optical fingerprint scanners

Facial Recognition

Polarizers optimize 3D facial recognition by reducing unwanted reflections and enhancing contrast. This enables more precise identification in biometric access controls, mobile devices, and security applications.

Detection of Hazardous Substances
(e.g., Explosives, Drugs)

In spectroanalytical systems, polarizers help filter specific light wavelengths and enhance the detection of signals from hazardous substances. This increases precision and reliability in security screenings at airports, law enforcement, and threat prevention.
