Everlight Introduces Infrared LED For Iris Recognition
New 810nm LED offers precise recognition and excellent heat dissipation
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.
AngelTech Live III: Join us on 12 April 2021!
AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST)
and will feature online
versions of the market-leading physical events: CS International
and PIC International
PLUS a brand new Silicon Semiconductor International
Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.
2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.
We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.
We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.
Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.
Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.
So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
