PSC’s optical filters guarantee that your device only picks up light at the wavelength it is supposed to, and that it picks up the maximum amount of light for that wavelength. That provides enhanced quality and a crystal clear signal.
Iris scanning is a biometric recognition and identification method. Via video images of the unique iris pattern, the application is able to recognize an individual. It is applied for access control, border crossings etc. The technology is often based on near infrared wavelengths. Hence, a NIR filter is used.
PSC manufactures NIR acrylic filters. We call these filter solutions Solaris™ IR S306. Our casted black or very dark red acrylic filters combined with anti-reflection (AR) or optimised AR surface treatments result in excellent filter solutions for iris recognition devices. With the optimised AR surface treatment it is possible to obtain extra high scanning performance, with improved precision and faster recognitions.
