LED and optoelectronics manufacturer Everlight Electronics, has launched the NIR-C19M 810nm LED series for non-contact optical iris recognition.
Recognition with the NIR-C19M is precise, quick and offers excellent heat dissipation with a thermal resistance of 4.38ᵒC/W, making it perfectly suitable for applications in security surveillance systems (access control) and portable handsets. The dimension of NIR-C19M series is also only 3.5mm x 3.5mm x 2.3mm, making it particularly desirable for space-constrained portable devices.
The NIR-C19M works with a wavelength of 810nm and uses an advanced ISP image processor together with a CMOS imaging sensor to receive the infrared reflection of the human eye and identify the iris. Its innovative optical design achieves a clear high reflection rate, a small angle (FOV=25) and a radiant intensity of up to 2,700mW/Sr below 1,000mA. The device has also passed IEC62471, a safety regulation to prove that no harm arises to human eyes and skin.
