Uses an advanced ISP image processor together with a CMOS sensor to receive the infrared reflection by the human eye for iris identification

Smart biometric is capable of identifying a user’s unique fingerprint, voice and iris patterns. Face recognition avoids the problem of recalling traditional long passwords. Infrared LEDs for non-contact optical identification have a compact size, strong security and quick recognition speed, which makes the technology increasingly sought after.

Offering exactly this is the NIR-C19M series. Having a wavelength of 810nm allows a clear contrast effect, making it possible to read the pattern of the iris. The recognition process is precise, quick and features excellent heat dissipation, which is perfectly suitable for iris recognition applications in security surveillance systems (access control) and portable handsets.

The NIR-C19M series for non-contact optical iris recognition adopts a moulding manufacturing process as it results in a smoother surface and increased reliability (as compared to the traditional glue dispense manufacturing process).

The NIR-C19M series uses an advanced ISP image processor together with a CMOS sensor to receive the infrared reflection by the human eye for authenticating iris identification. Its unique optical design achieves a clear high reflection rate, a small angle (FOV=25) and a radiant intensity of up to 2,700mW/Sr less than 1000mA.
The heat dissipation with a thermal resistance is of 4.38℃/W.

Additionally, the dimension of NIR-C19M series is 3.5 x 3.5 x 2.3 mm, which is optimal for space-constrained portable devices.

The device has also passed IEC62471, a safety regulation to prove that no harm arises to human eyes and skin.
