SFH 4181S

The OSLON P1616 Infrared series is designed to provide efficient high power infrared illumination for compact designs as it comes in an ultra-small package. The SFH 4181S have an integrated lens with a viewing angle of ±35° and are available as stack version, therefore being the perfect fit for applications requiring a high radiant power and a homogenous bright illumination area, such as 2D face Recognition for user authentication in laptops and smart door bells for example. This high power infrared emitter (940nm for reduced red glow) typically used in access control (IRIS/vein scan, face recognition), CCTV surveillance, eye tracking, gesture recognition, safety, CCTV computing, user authentication and security.
