Everlight has launched a new infrared LED for iris recognition. Called the NIR-C19M, the LED has a wavelength of 810nm which allows for the clearest contrast effect to read the pattern of the iris, according to the company.
Everlight says that the recognition process is precise, quick and features excellent heat dissipation, making it suitable for iris recognition applications in security surveillance systems (access control) and portable handsets.
The NIR-C19M series adopts a moulding manufacturing process which, compared to the traditional glue dispense manufacturing process, results in a smoother surface which not only enhances the look but also increases reliability.
The LED also features an advanced ISP image processor together with CMOS sensor to receive the infrared reflection by the human eye to authenticate iris identification. Its optical design achieves a clear high reflection rate, a small angle (FOV=25) and a radiant intensity of up to 2,700mW/Sr below/less than 1000mA.
The heat dissipation with a thermal resistance of 4.38deg/W is said to be superior to any other competing product in the market. The device has also passed IEC62471, a safety regulation to prove that no harm arises to human eyes and skin. The NIR-C19M measures 3.5 x 3.5 x 2.3mm.
